Say Hello To The Future!

JL Audio are a renowned American manufacturer of the highest quality subwoofers, amplifiers and speakers. Some of our best sounding installs have been based around JL Audio products and it is true to say that there is something for everyone within the range.

I was lucky enough to attend a training day with JL Audio’s head of training, Steve Turrisi in March 2017 where, without exaggeration, I was shown the future of car audio. This year JL are launching a fabulous new range of products so let me describe what I was shown.

In June we will see a new entry level speaker range designated C1. These look set to clean up on the simple speaker upgrade market. They are robust, great sounding and very easy to fit as they come with installation collars to cater for different vehicle apertures.

 

 

I am sure I will be fitting a lot of these in the near future.

As mentioned there will also be a new ultra high-end speaker set, the C7. This speaker has been designed from the ground up to be the absolute best. Drawing from JL Audio’s many years of experience this will be a milestone in audio performance. It will not be cheap but the best never is.

Expect a price tag in excess of £2000 for these magnificent drivers but I am sure we will not be short of takers when these launch in summer 2017.

Already available are the new RD series of amplifiers which fill the gap between JX and XD. Boasting huge power output from a small chassis I have installed quite a few now and they are extremely impressive.

The RD amps are extremely well priced for the level of performance they deliver, the build quality is amazing and of course, they have the legendary JL sound. Available in mono, 2 channel, 4 channel and the incredible 5 channel every application is catered for.

As if this wasn’t enough I’ve saved the best till last. Available now are the stars of the show. JL Audio’s new line of digital processors the FiX and TwK.

With these products, we will no longer have to endure the sound supplied by factory head units that cannot be swapped out. The BMW, Ford, Audi and VW factory radios can be made to sound amazing. Couple this output to a great amp and speakers and there are no limits to how good your car could sound. This is thanks to the amazing TuN software developed by JL and an installers dream come true.

As can be seen, the software gives me complete control over every aspect of the audio system. There is nowhere near enough room here to describe all the features but trust me, this is a game changer. Car audio will now take the next great performance leap.

For details of all these great new products call me on 01625 432707 or better still call into our shop on Sunderland Street in Macclesfield.

Practicing Safe Sound

There are many ways to upgrade your car audio system and let’s face it, most cars need it. I’m looking at you BMW, VW and Porsche in particular! It is not always possible to upgrade the head unit but it is always possible to improve the speakers. At Car and Home Stereo, we carry speakers by JL Audio, Audison, Hertz, Rainbow and others. This means we can choose the right speaker to suit the car and the customer. We will carefully install your speakers with custom built collars and fittings as well as add sound deadening in the door to improve its acoustic properties. The end result will be a vastly better sound without any cosmetic changes to your car.

And that is where we are finished but before you leave, a word of warning. Please take the time to run your new speakers in. The running in period varies for different speakers but generally, we recommend around 10 hours play time. Running in means keeping the volume at a sensible level without any large bass settings and we will always advise what should be the maximum volume for this period.

If this procedure is not followed your speakers may not fail but they will not reach their full potential, let me explain why.

A speaker is a transducer that converts electrical energy into sound and at the heart of the speaker is a coil of wire sitting inside a magnet. It is bright, shiny copper.

coil speakers good copper

It’s not necessary to know how it works but the important point is that when you pass electricity through a wire heat is generated and the higher the electrical current the more heat is generated. Now, this coil of wire is crucial to the accuracy of the speaker and it is protected by a thin coating of lacquer. This lacquer is quite soft when new and easily damaged by heat but if it is gently warmed over a number of hours the lacquer will harden.

I bet you can see where this is going! If a new speaker is subjected to a lot of power and played loud the voice coil lacquer will boil causing short circuits. Now while this will not necessarily cause the speaker to fail it will mean that the voice coil is not a single continuous wire which leads to a ‘lumpy’ effect within the magnetic gap. This, of course, means that the reproduction of sound is not linear and your investment will not reach its true performance capability. In extreme circumstances, the lacquer is burnt and expands into the magnetic gap which will cause a scratchy sound. These failures are non-reversible, cannot be repaired and are not covered under any warrantee.

So that is why we advise the running in period, to gently warm the voice coil lacquer causing it to cure. This hardened lacquer can now stand the heat of high power and your speakers will really perform as the designers intended.

I cannot overstate the importance of running in, a speaker is more likely to be damaged in the first few hours of use rather than over the rest of its life. At Car and Home Stereo, we want you to get the best possible sound from our expert installation so just hold back on the volume for a few hours, you’ll be glad you did.

 

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.

Demonstration of Distortion

An interesting situation occurred at Car and Home Stereo recently that I would like to share. It highlighted a phenomenon that is quite counter intuitive and led to some interesting discussions.

We have a demonstration Land Rover Discovery that has a simple, high quality audio system installed that is tuned to perfectly suit the interior acoustics. We always encourage our customers to sit in and experience it as it shows what can really be done with car audio. The amplifier that powers the system is the magnificent Audison 5.1K which develops a true 1650 Watts.

There is one pair of component Hertz Mille Legend speakers in the front doors and a Hertz Mille subwoofer in the rear.

A customer recently auditioned the system and we spent a good hour playing different types of music with a view to producing something similar in his car. He was completely blown away with the sound, couldn’t believe the clarity and how the sub blended perfectly with the whole system. And then he said ‘I love it, but it’s not very loud is it?’. In fact he reckoned his standard Ford system was louder!

Now I know just how loud our system is and the odd thing is that the cleaner the sound the less we perceive volume. Since we had some time I decided to run a little proof experiment with my customer’s car.

As part of our equipment set we have an industry standard spectrum analyser which is also equipped with an SPL meter. It was a simple task to set this up in the Discovery first and then the Ford to compare. As expected our Discovery hit 126dB easily, the Ford however struggled to hit 110dB. In real world terms this equates to a perceived doubling of power (a true doubling is 3dB but we don’t really hear it that way). The next test was the distortion level. By plugging an oscilloscope into the amplifier output we can measure the clipping levels. Unsurprisingly the Discovery registered less than 5 percent distortion at full volume as this was how it was set up. However the Ford reached 5 percent at a little over half volume and climbed to over 25 percent.

There is no arguing with the figures so what is going on? Simply that the higher  distortion levels were being registered as unpleasantly loud and our brains are trying to get us to turn it down! Distortion is the quickest way to destroy a speaker or indeed your hearing.

At Car an Home Stereo we value our customers and hope to be providing high quality audio systems for many years. A distorted sound system will very quickly do serious harm to our hearing and that is why we only choose the best equipment and like to carefully set these up to give the best possible sound. Brands such as JL Audio, Audison, Hertz and Dynamat may not be the cheapest but certainly are amongst the best. The fact that when installed correctly they can deliver an amazing sound makes them excellent value for money.

As to my customer with the Ford, he now has a fabulous system based around a JL Audio amp and speakers with a Rainbow active sub. He loves to play it loud and I know it will give him years of pleasure without doing any harm.

If you want to experience the Discovery sound system or would like to discuss how we can improve your car please all us 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.

If you enjoy the power and performance of modern films you should add the incredible Acoustimass 300 sub. This relatively small unit can be mounted anywhere in the room as it utilises a wireless connection to the sound bar. All it requires is a mains connection. The AdaptIQ software can perfectly integrate the sub into the acoustic environment.

The second optional upgrade is the Acoustimass 300 rear speakers.

Selecting a Subwoofer : The Nitty Gritty

Most music consists of a full range of audible frequencies, from low bass (bass guitar, cello etc) to high treble (cymbals, piccolo) although a notable exception is John Cage’ Four minutes and Thirty Three seconds. In simple terms – the lower the sound, the longer the sound wave and the more energy required to generate it. In practical terms – bigger speakers and a more powerful amplifier.

IMG_0584

“Bass is an essential part of music and is the part that adds the drive and excitement, try to imagine Michael Jackson’s Billie Jean or Prodigy’s Fire Starter without any bass, for example.”

“Can’t we just use a more ‘bassy’ speaker?”

To explain why this is not really the answer we need think about what a speaker is doing. In its simplest form a speaker is a vibrating membrane that is generating sound (pressure) waves and to produce lower sounds, the speaker cone has to move more slowly and further. This is no problem on its own but at the same time we need it to produce the mid and treble frequencies. These sounds require a very quick response and result in a very complex vibration pattern. Expecting a speaker to do both low and high frequencies inevitably ends in a compromise of both. The practical result of this compromise is at best a muddled, less defined sound and at worst a distortion that will lead to the destruction of the speaker. The only solution is a dedicated bass speaker, a subwoofer.

_DSC0173

Fortunately there are a wide range of compact, high performance woofers on the market now. Speakers that will operate in very small enclosures and take up minimal space. In a lot of cases, where I’m upgrading a factory Bose or Meridian system, I can use the existing bass speaker location for a completely stealth installation. In many cases I can use wheel wells, under seat locations or custom build enclosures in boot recesses. Even when none of this is possible there are woofers from Jl Audio and Hertz that offer spectacular performance from a unit little bigger than a couple of shoe-boxes.

_DSC0182

At Car and Home Stereo my system designs are always sympathetic to the vehicle but most of all it is my passion for music and great sound that drives my recommendations.
