Vehicle Specific Systems: BMW E90

This car is a firm favourite of ours especially in the M Sport however, the stock audio is nothing short of terrible. There is a distinct lack of any real bass and even with the optional stock tweeters there is no sparkle or liveliness in the sound. A lot of owners are unaware that there are bass speakers are located under the front seats as the low-frequency performance is so bad. There are of course many options to improve the audio but perhaps the simplest is to replace the speakers. The BMW speakers are a unique size and fitting a standard set can be difficult, fortunately, there are several companies now making BMW specific replacement speakers. Foremost amongst these are Rainbow, a German company specialising in some very high-end speakers.

The Il-c8.3 kit is suitable for all BMW E9x and F series and comes complete with all OE style connectors. All speakers will fit in the standard location with the minimum of modification. What’s more, all the original speakers can be re-installed when the car is sold or returned.

The difference between the Rainbow and the stock speakers is astonishing even without fitting an upgraded amplifier. The sound stage is better with vocals being presented cleanly, the mid range is much less confused and at last, there is a decent bass response. It is possible to just change the door speakers but I would highly recommend replacing the whole set.

Another popular vehicle with an underwhelming audio system is the VW Golf. Like the BMW the stock system has no sparkle and again a poor bass response. Once again Rainbow step in to provide a direct replacement speaker set, one for the VW Golf Mk5 and one for the Mk6. Available in three and two-way, this upgrade immediately lifts the whole audio soundstage to a new level. The kit comes with all fittings and collars required so it is possible to fit yourself if you wish.

Of course, you may be looking for a complete upgrade for your Golf Mk6 or 7 and here we can turn to the masters of car audio Audison. They have designed a specific system for this car that replaces the speakers as well as adding a custom tuned amplifier and a  super slim sub enclosure designed to seamlessly fit the car.

 

This system brings a whole new dimension to the audio system with a full digital signal processor that is built into the compact amplifier that sits discreetly under the seat. It has been developed from painstaking testing and tweaking to make sure that it both integrates perfectly with the stock car and provides the best possible sound. Again this kit comes complete with everything you will need to install it but unless you are comfortable removing the trim and panels from your car we would recommend letting us install it.

Of course, not all cars are covered with a ready made upgrade kit and this is where Car and Home Stereo can really help. Over the last thirty years, we have seen almost every type of vehicle and our comprehensive knowledge allows us to design and install audio systems that will delight. We strive to design systems that will blend perfectly with your car whatever your requirements may be. From the simplest speaker upgrade to a complete multimedia systems our aim is to put a big smile on your face every time you listen to it and that is what music should be about.

 

If you are ready to start your journey to better sound then please call Tim on 01625 432707 or better still call into our shop on Sunderland Street in Macclesfield for a chat and a demonstration of the best that car audio can be.

Perfect Timing

Let’s talk about sound and specifically how we perceive a sound’s location, (we’ll come back to the elephant in the room). To do this we need to understand what sound is and how it travels.

In its basic form sound is a compression wave propagating through a medium. Think of ripples in water travelling away from where the stone hit. The sound is exactly the same but travelling through air. Travelling very quickly by the way at over 700 miles an hour.

The defining characteristic of a wave is the fact that it has high and low points.

 

Points along this wave are known as the phase and describe whether the wave is positive or negative and by how much. Now for the clever bit. Consider a listener sat in a chair with their eyes shut, someone off to their left claps. Of course, he can tell it was to his left but how? We all have two ears so it might be true that we can detect the time difference between the sound reaching our left and right ears. But at 700 miles an hour this is a VERY short difference and if true it would mean that all frequencies could be located but as we know the lower the sound the harder it is for us to locate the source.

What we are predominantly detecting is the difference in the phase of the wave between our ears. By measuring the difference between the high and low points on the wave our brains can very accurately calculate sound location and create our spatial awareness. That is why we cannot locate very low (very long wave) sounds as the difference in the phase between our close set ears is minimal (think about thunder).

So now we know this how can we use it in the car audio environments?

One of the big problems in the car is that we are always sat closer to one speaker than the other, therefore the stereo effect is foreshortened to one side. A very crude way to combat this is to put the balance off to one side to compensate but that does not enhance the stereo performance. What we really need to do is place the speakers an equal distance from the listener. Difficult if you are not in a McLaren but we can fool our ears into thinking the sound is coming from somewhere else using phase.

By carefully manipulating the phase of the sound from the speakers we can create the effect that the close speaker is actually further away which leads to a much wider stereo field. This manipulation is very delicate as you can imagine but as a member of the FourMasters network, we are equipped with a sophisticated range of tools and software to achieve this.

The difference between a standard setup and a phase aligned one is astonishing. The whole soundstage comes alive with instruments and vocals spread across the car in a very lifelike and live performance. It is possible to compensate for difficult speaker positioning (BMW) or over separated speakers (VW).

Of course, you will need to have the products to permit this tuning and fortunately, there is a range of sophisticated processors from Audison and Hertz that offer these features. Products like the astonishing Bit family from Audison. These devices give me the capacity to completely shape the acoustic performance in your car which means you will have a completely bespoke sound that perfectly complements your car and your personal tastes.

We have a demonstration vehicle always available at our shop on Sunderland Street in Macclesfield. In this we can demonstrate the difference between a standard and phase aligned sound, we would love to show it off if you want to pop in for an audition.

Oh and the elephant? Elephants communicate their location by stamping on the hard ground. This creates a very low-frequency sound which can travel a great distance. You or I could not locate this low sound but elephants can, why? Because their ears are much further apart and can detect the phase differences!

What To Look Forward To In 2017

It’s good to be back after the festive break and there is a lot to look forward to in 2017.

World renowned audio manufacturer Audison have just announced their new Thesis speaker range. The Thesis amplifier represents the absolute pinnacle of performance without compromise and now there is a speaker set available to match. If you are looking for the absolute best possible sound then this is it.

adison speakers

Staying with Audison, the new slimline Prima subwoofers and enclosures offer stunning bass performance from a very compact form. These will appeal to anyone who does not want to sacrifice much boot space but still demands a Hi-Fi response.

There will also be a new Prima Pack custom installation kit for the BMW 1 series. This car has always had a very disappointing standard audio system and the Prima Pack is a tailored solution comprising the stunning AP amplifier, a custom Prima speaker pack and compact subwoofer. As with all the Prima Pack systems the factory head unit remains unchanged but the audio performance is greatly enhanced by the AP amplifier. The speakers fit perfectly into the factory locations and the sub is designed to blend seamlessly with the factory trim.

On the other side of the Atlantic, JL Audio have released their amazing new processors, the new Fix and TwK.

jl audio

The FiX range is simplicity itself to use and automatically deals with all the anomalies inherent in vehicle factory head units. Building on the success of the CleanSweep processor, the FiX can automatically de-equalise audio streams and can even remove spurious time alignment errors giving  a flatter, more open sound from which we can build a better audio system.

The new TwK processors take this a huge step further by allowing access to a vast range of processors via the JL Audio software. From input/output configuration to full spectrum equalisation, this product means that every installation can be tuned to perfection.

Over the break we have been busy building new demonstration stands to showcase some of our best car audio equipment as well as tweaking our Land Rover Discovery demonstrator. This simple car audio system still astonishes me with its clarity and power showing what can be achieved with just one pair of speakers, a subwoofer and amplifier. If you haven’t heard it and can come down to our shop on Sunderland Street in Macclesfield I would encourage you to do so, it is sure to impress.

Our focus, as ever is on installation of the highest quality whether it is a simple dash cam or a full blown custom audio system. We are proud to be a part of the national FourMasters group offering the highest installation standards and a three year warranty on installations.

Please feel free to pop in or give me a call on 01625 432707 to discuss ideas and start your journey towards better sound!

Wishing you a happy new year!

We hope your 2017 has got off to a good start!

Here, at Car and Home Stereo we already have some exciting, new products coming through the door. Come to our shop on Sunderland Street, Macclesfield, and see what we can do for you.

Keeping It Simple with Bose

For many years Car and Home Stereo has been synonymous with Bose Hi-Fi. Over the years we have installed hundreds of sophisticated and powerful home theatre, multi room systems. It’s true to say that most of them are still providing their owners with daily pleasure, such is the reliability of Bose audio.

While every system was designed to our clients needs they all had one thing in common, cables, and lots of them! We had to spend as much time installing cables as installing the system not to mention the in depth design process to determine where everything needed to be. All this hidden detail could amount to a sizable cost. Now the whole process has become an awful lot simpler thanks to WiFi!

Wireless streaming of your music is not a new idea of course but most solutions have been of average quality often with clunky user interfaces. What is really important, apart from high quality sound of course, is that it is easy to use. The Bose SoundTouch wireless music system is just such a perfect blend of quality and simplicity.

The SoundTouch system can communicate with any WiFi connected device in your home be it Apple or Android, PC or Mac. It will search for any music you have stored and allow you to play it anywhere in your house. If you use a streaming service such as Spotify or Deezer you can seamlessly call up your favourite music directly from the Bose control app. There is even a smart Bluetooth capability to allow direct streaming to multiple devices around your home and of course there is access to the whole world of radio via the Internet.

Now you can have a whole house, high quality solution without all the complex cabling. Whatever your needs there is a SoundTouch wireless system available. From a full 5 speaker surround sound home theatre system for the living room to a simple stand alone music player for the kitchen. There is even a wireless amplifier that can be used for outside or as bathroom speakers. The amazing SoundTouch 300 sound bar is extremely popular as is the Sound Touch 20 free standing unit.

The possibilities are endless and I would urge you to contact me at Car and Home Stereo on 01625 432707 to discuss the ideal system for you.

Christmas ’16: In Retrospect

As we come to the end of another trading year it seems fitting to look back at what has changed for us. Personally I think the development of affordable and powerful Digital Signal Processing by Audison has been a complete game changer. At Car and Home Stereo we have always embraced any new technology that will improve the in car audio experience. I can remember fitting Phoenix Gold analogue graphic equalisers in the 90s and spending ages carefully setting them up for the vehicle acoustics. Then the customer’s ‘expert’ mate would have a go, dial in the ‘smiley face’ EQ curve and ruin the sound.

When digital systems started to appear I was delighted as there were no more sliders to get fiddled with. I was one of the first to install the Phoenix Gold TiDEQ and it was brilliant if not tearfully expensive. Inevitably, cheaper systems appeared from other manufacturers but they were short on processing power and were distinctly underwhelming.

Fortunately Audison picked up the baton of digital signal processing and ran with it.

With powerful software and a host of automatic and manual signal conditioners on board, the Bit range of products now allow me to take any car and be confident of a stunning audio result, regardless of system installed and at a more than reasonable cost.

Another one of my favourite company is JL Audio. Their range of subwoofers and amplifiers are almost unmatched for performance and fidelity. Ten or more years ago we were installing plenty of subs but they were large and needed large enclosures for the best sound. This meant eating up lots of boot space, many customers just did not want that and so compromised on the bass performance. JL Audio, already masters of subwoofer design, set out to help everyone get the best bass performance regardless of available space. In the last couple of years they have produced some spectacular speakers that will operate in almost ridiculously small enclosures. Their TW range particularly so. At Car and Home Stereo sound quality is our first consideration and adding a subwoofer is to my mind essential, now we have the products to allow this regardless of space.

Another product that has really impressed me this year is the SoundTouch 300 soundbar from Bose.
bose sound bar
This very stylish soundbar not only looks fantastic with its black glass top and minimal design but it has a sound that will quite simply amaze. As one of the undisputed leaders in sound reproduction technology Bose have delivered a product that defies reality. Although it is only a single bar it manages to create sound from places far beyond its size. Close your eyes and you will be convinced that there are speakers all round you! If that is not enough then you can also add the optional powerful subwoofer and even wireless rear speakers for a true surround sound experience. Of course it also contains the Bose SoundTouch technology which is just about the best music streaming system available today as the icing on the cake!

And if you are stuck for a last minute Christmas gift, the Bose SoundLink Mini is perfect.

Don’t be fooled by the diminutive size of this little Bluetooth player, the sound is amazing. Full portability thanks to its long life rechargeable battery and a rich, full sound whether on its charging cradle or taken on an outing.

All that remains is for us to wish you a happy Christmas and New Year. Here’s looking forward to 2017 and all the exciting developments that are on their way for car and home audio.

Please note that we will be shut for the Christmas holiday from December 25th until January 3rd. Have a happy and musical Christmas!

Simon Says? Speakers Please!

For this instalment let’s look at speaker installation. The speaker is the last piece of hardware between your music and your ears and as such has an awful lot to do with the sound you hear.

The science behind the speaker is extremely simple; pass an electric current through a wire that sits inside a magnetic field and the wire experiences a force, vary that current and you vary the force. Of course this demonstration produces no sound but if we attach the wire (or coil) to a diaphragm (or cone) we have the nucleus of a working speaker. The electronics in the amplifier produce the varying electrical current and the speaker responds, creating the highly complex vibrations in the air that we hear as music.

The above description is of course highly simplified and in reality there are many more aspects to speaker design. We have to consider the weight of the moving parts, the resistance to movement within the materials themselves, the linearity of the magnetic field, the quality of the coil wire, the damping to prevent uncontrolled excursion, stability of the frame and so on and so on! Fortunately all of these considerations are engineering problems and this means that better engineering will lead to a better product.

When Mr. Ford or Mr. Audi or even Mr. Porsche are told that they have to put speakers in their cars their first consideration is not about quality even when they enlist the help of respected Hi-Fi companies. Their overriding concern is one of reliability. A blown speaker is a warrantee issue and that costs money. The trouble is that a speaker that can survive heavy metal hard core country rap at full volume has to be made super resilient. This speaker is not going to be able to respond to the subtle nuances of any quality musical performance.

pic-of-sam-bad-sound-face

At Car and Home Stereo we are always going to install a high quality speaker, carefully selected to match the vehicle and musical tastes of the customer. This is where our installation skills are needed. The average car door is a challenging place for a speaker. It is a steel box that is often wet inside, can be freezing one day and very hot the next. There are moving parts within it and it is subject to a large amount of vibration and noise. Let’s look at a typical installation addressing each point.

First of all we carefully remove the inner trim making sure that all clips and seals are retained. After this the next job is to treat the metal skin with sound deadening material which will absorb road noise and any vibrations within the door.

dsc_0002

Particular attention is paid to directly behind the speaker as this will absorb the sound generated by the back of the cone and prevent reflection back into the door panel.

Once the outer skin has been treated we apply a foam barrier to the inner skin. This forms a watertight seal and acts as a thermal and acoustic barrier. This keeps the car warmer in winter, cooler in summer and again reduces road noise. The difference these treatments make to a car is astonishing.

dsc_0003

Now we come to installing the speaker. The factory units are often built to fit so we must make panels and collars to allow a perfect fit to the door.

dsc_0004

It is very important that no moisture gaps are left as it may come as a surprise to know that doors are designed to let rain flow through them. Any gaps could lead to a wet floor so we make sure everything is sealed with high quality silicone, both the collar and the speaker, this also ensures no air gaps to compromise the speaker performance.

dsc_0006

Quite a lot of work but absolutely worth it. These Audison APK speakers sound great anyway but by treating the door they are at least 30% better.

If you would like to know more about how we can improve the sound in your car please call Tim on 01625 432707.

Cutting Edge! with JL Audio

Today let’s look at the range of fantastic high performance products from JL Audio.

Formed in 1975, JL Audio are based in Florida USA and from the very start, their passion has always been to produce the best possible products. Originally they concentrated on sub-woofers and they quickly earned an enviable reputation for amazing power and performance. More recently JL Audio have expanded their range to include speakers and amplifiers with the emphasis once again firmly on quality and performance.

_dsc0055

It’s true to say that the JL Audio range of subs has something for everyone. From small, discreet custom enclosures to high output monsters to true Hi-Fi quality audiophile drivers. The engineering expertise at JL Audio means that even their least expensive sub still sounds amazing and will work in a relatively small enclosure.

Every in car system will benefit from the installation of the dedicated bass speaker and at Car and Home Stereo we will make sure that it is fitted and set up correctly.

 

 

_dsc0047

Of course a sub-woofer always needs an amplifier and so the logical step for JL Audio was to produce their own range. Car and Home Stereo is proud to be a JL Audio Signature dealer which means we carry a wide range of products. The XD range of amplifiers is a particular favourite of mine. They only take up a small amount of space but deliver an amazing performance! From the compact XD 200.2 to the immensely powerful XD 1000.1 they offer a level of flexibility and performance unparalleled to anything else.

Never a company to stand still, JL Audio have just upped their game and released a new range of amplifiers designated the RD series.

 

_dsc0052

These units are extremely good value for money and sound amazing as they are based on JL Audio’s NexD D class technology. Multiple input configurations are available making for pretty much universal compatibility while the small footprint means installation is straight forward.

_dsc0048

JL Audio speakers are some of the best around. Even the entry level TR series have a detail and clarity many other more expensive speakers cannot compete with. Taking a step up to the C2 series and we are well on the way to a true Hi-Fi performance. Where space is tight the C2 400 (a 10cm speaker) punches far above its weight for low frequency. This has become my first choice for the Land Rover Defender and is more than capable of overcoming the road noise while still producing a full range performance.

One speaker range stands out though, the C5. This speaker range has a natural and transparent sound that is simply breathtaking. OK they are not cheap but that is not the point, where high fidelity is the goal you have to go a long way to beat this speaker. The tweeter alone is one of the smoothest speakers I have heard with vocal and piano pieces a joy to experience.

And of course there are many more products in the JL Audio line up. There are processors that allow seamless integration with factory standard audio systems. These units can repair the poor performance of the standard head units found in BMW, Audi,  VW and others that can not be changed meaning you do not have to put up with the stock audio.

There is also a range of very high performance marine speakers used on the like of Sunseeker power boats. However at Car and Home Stereo we are land locked and there has never been a big demand for these here!

The most important point is that, with JL Audio, we have a range of products that can suit any application and any performance requirement. We have the experience and resources to make sure we offer and install the best possible sound at any budget.

 

Give Tim a call to discuss your requirements or, better still, call in to the shop in Macclesfield for a coffee and a chat.
