Our bestseller cables!!..

Why van den hul?

Go Dutch! Okay, nothing of that sort. Van den Hul (VDH) is a dutch company that has been around for over 20years. The company began operations with a main objective, which still stands today to improve the quality of both phono-transfer and the quality of signal transmission in a broad sense.

Over the years, the company continues to apply new unique techniques, solutions and state-of-the-art technology based on their inventions, findings and listening experiences.  This experience is gained taking into account the consumers expectations, which include audio industry and professionals in the recording industry.

Selecting cables may seem like a basic task, but it is by no means simple. Cable companies are widespread and plenty. Many having to prove themselves as not being labelled ”snake-oil”. Snake oil meaning worthless (just like various liquid that are sold as medicine but medically worthless).

Cables themselves look like snakes and some makers make it so enticing by sleeving them into plastic snake skin jackets and thick rubber hoses. Therefore, when selecting cables it is best to focus on performance gains, towards a specific goal and take the looks with a pinch of salt.

Fortunately, VDH cables choose not to do dress up marketing. As important as marketing is to any company, VDH sticks to simple packaging, professional and non fancy approach. They focus on making the cable longstandingly durable,  clean/green from environmental influences and best of all, damn good sounding.

So, why does Audio Creations use van den hul for car audio? Car audio suffers the same fate as home audio and audio/video, but (even more) to a  harsher degree (because of reflecting surfaces in the car) in it’s battle against digital sources, digital reproductions and boringly clean and lifeless music. We find that VDH cables allows us to combat digital boringness more effectively by injecting more analogness in the music.

History of VDH itself proves that the company spends its time and resources making high-end cartridges, and you can’t expect any more analog than that. Analogness preserves musical quality and VDH does just that in a more outstanding manner. Outstanding in the sense that it balances out the need for lowest distortion possible, best detail and resolution possible, realistically solid imaging and control while preserving the realism and essence of physical fullness in the music. 

Make way for van den hul cables in your audio system, and discover how tuning can be less painful and snergy between your high quality or high-end equipment start to take form and perform optimally. You owe it to your equipment to try it out…

NEW Map, Same Location

Saturday, October 9th, 2010

Since the tunnel leading to NZX Commercial Centre had been made one-way (out), we cannot rely on the GPS coordinates to lead you here from the LDP highway. Take note that GPS will try to direct you through a one-way tunnel. The tunnel can still be used to make your way out to LDP, but since it is no longer two-way like it used to be, you have to follow this map and take the first tunnel, a mild detour. An easier way is to use the highway leading to the Subang airport which is easier to comprehend.

Kindly follow this new map (courtesy of canaanland website). Observe the instructions on the map.

If you’re taking public transport, please adhere to the following bus route: From Kelana Jaya LRT Station, take RapidKL Bus T607 to NiuZeXui Ara Damansara (www.rapidkl.com.my scheduling details)

The good and the bad about car audio equalizers

Wednesday, February 17th, 2010

Equalizers (EQ) are great tools for fine tuning those little frequencies that is missing in your system.

EQs cannot be applied to solve foundation problems. In fact the more EQ is being used the worst off the system can be tonally.

Our goal is to naturally EQ the system using as much as possible, cable, power management and associated equipment etc., while maintaining an external EQ to fill in the minor missing gaps.

EQs must be flexible, less digital inclined and should not alter the tonal palette drastically.

It should be analog sounding where possible and have a good solid power supply section. EQs can help restore some voltage drop by enhancing back the signal before it is fed to the amplifiers or next chain of equipment.

That is all EQs should do. It is not a magical wand to cure system problem. It is an aid and not a cure.

Without EQs, a system can sound lonely, a tad dry and subdued (depending on systems). EQs enhances the presence, brings back hat little that is missing without overdose.

At Audio Creations (AC), we use Audio Control (AC) not because it is synonymous with AC but due to it’s long standing solidity and quality. We are experts with AC units and we know how to identify which units are better than others and what joys it can bring you, and what it cannot do.

We highly recommend modifications for EQs and crossovers (primarily AC units) by means capacitor upgrades and high-end modules. They make significant tonal benefits and improve the grip and control in the music material. We offer these mods, for both new and used alike.

Know the boundaries of what an EQ can do, and it can be a useful tool to bring you a step up in your car audio system.

Enjoy tuning….

Do I need an expensive, double-stacked, triple-stacked, high-powered subwoofer?

Tuesday, February 16th, 2010

Subwoofers!! Can’t live without one, yet some people are trying ways to do without them. Can we come up with a good car audio system without one? We cannot lie to you, the answer is NO.

I have seen many “champions” spend thousands on a good imported subwoofer but expect to get it all up and running for lows couple of hundred ringgit (RM). You see that commonly in Malaysia because imported car audio equipment is expensive here due to the weak currency, hefty shipping and high-taxes. Therefore people tend to stinge on the application and installs. Furthermore, if you spend on expensive, power hungry (demanding) and low sensitivity subwoofer, be prepared to splurge equally on amplification.

Subwoofers like any speaker driver sounds as good as how you build them. Enclosure, crossover and placement all plays an important part. In other countries, one may spend as much on making the enclosure right as they have invested on the subwoofer driver itself. Some people even build a couple of enclosure to see which ones works best and sounds best in their system.

Sometimes it takes a long time for a person to decide on what subwoofer to buy, but the minute they get it, they rushed for the installers to slap it into a box. Guess what, the choice is usually the smallest sealed enclosure. What if the bass is too hard and does not go low? Stuff it with polyfill?

Building a right enclosure is not rocket science nor it’s a simple task especially in a  car audio environment. It is still a tough nut to crack but with the right expertise, equipment and know-how, you’ll fall in-love with your subwoofer again. It can be a budget JL audio WO, to expensive JL audio W7, to exotics like Scanspeak 23w and Phase Aliante, all the same rules apply.

You don’t need an expensive subwoofer per se. Look at home audio subwoofers, many of them use reasonably affordable drivers, no where high-end! Yet, some home audio ones are very expensive (an indication would be rm5,000-rm15,000). Why? Because it has a built in plate amplifier? Could seem like a good reason but it is not. We know the prices of those plate amplifiers. 

Remember to spend wisely. Equal amounts to material, application and install. Efficiency, displacement and tuning goes a long way.

Mounting amplifiers upside down!

Wednesday, October 28th, 2009

Sounds dumb isn’t it? Yea, but some people still do it, mostly not due to stupidity but because of space constraints.

Amplifiers come in different designs, but all designs use a heat sink to dissipate heat, some coupled with either a fan or two for additional cooling. Some amplifiers have no fan at all but depend solely on sufficient heat sinks to handle the heat.

Having said that, common sense tells us that to let the heat sink do it’s job, it must be ventilated and heat should not be trapped on it, around it or channeled to it from hot surfaces, devices or heat from the sun. If you feel there is insufficient ventilation, by all means add a fan or relocate it to a cooler spot, an area which does not absorb or trap heat.

The reason why I bring this up, is that lately we have seen a few cases of overheated amplfiers, and in extreme cases damaged pcb boards, severely premature amplifier life and “pregnant” or buldging capacitors as part of the consequences. Particularly in scorching summers or hot climate countries all year round, where additional care must be taken to keep your gears cool and within operating range.

Last week, I solved yet another “ignorant” install, failing to understand the very basics of car audio safety and maintenance. The amplifer in question was a Zapco Reference 1000.4, a high powered 150watter x 4 running only the fronts (there is another amplifier for the subwoofer).Firstly, this is a very slim unit and secondly, it has no fan in-built. The amplifier was mounted upside down just below the rear parcel shelf in the trunk.

In a hot country like Malaysia, heat builds up considerably fast in the cabin space and equally fast in the enclosed trunk space. Your dashboard, just beneath the windscreen and the rear parcel shelf, just below the rear screen soaks up the direct sun when you park outside in the open. 

Since the amplifier is mounted right below the rear parcel shelf, heat is transferred to it direct from the mounting screws and gets trapped with little air movement. This results in the amplifier getting extremely hot (untouchable) even after 5 minutes of normal use.  Naturally, the amplifier shuts down thanks to the build in thermal proctection.

During the mornings and nights, the amplifier could play a little long before turning off by itself. The installer failed to address the problem and blamed the amplifier for being faulty. 

Another bad but not as seriously faulted install that I have seen many times is one amplifier mounted vertically on the rear seat and just below it, mounted  flat/horizontal on the floor trunk another amplifier for subwoofer duties. Naturally, amplifiers run hot and heat goes up, especially when you are running your subwoofers hard or for long-hours! The heat passes through the amplifier above it. Not a big problem but could be avoided if you care for your gears.

Love your amplifier, maintain it well and it will serve you for years. Use a fan if you have to (note: fans can induce external noise and also noise into your system) but better still use our common sense.
