Authorized dealer

For over two decades, AudioControl has been designing and manufacturing award-winning autosound products at our factory located in the rainforests of the Pacific Northwest. During this period, countless sound-off winning contestants have chosen AudioControl products to give them the competitive edge. "Can you really win without AudioControl", was part of an article written commenting on competition winning systems. Nothing sounds better than an awesome recording played back on a kickbutt system. Unfortunately, the acoustics of your vehicle can take away from your systems performance. While AudioControl products do not change the laws of physics (although they act like they do), autosound enthusiasts have long known that AudioControl products "make good stereo sound better".

The Epicenter - Bass Restoration Processor

AudioControl's legendary bass restoration circuitry, The Epicenter, brings out the best bass in any system. Whether you like rock, jazz, hip hop, country, banda, classical, CD's, MP3's, or cassettes, you will love how The Epicenter makes your system sound. More Bass... Louder!!

The unique bass restoration circuit of The Epicenter, originally patented by AudioControl, looks at the low frequency harmonics that are in the upper frequencies and uses them to recreate the lower bass fundamentals that have been compressed, rolled off, or simply removed. The chart Linked Here shows what it does for the signal. What it does for you, is provide deep earth-shaking bass that you've never heard before.

Key Features:

Patented Bass Maximizer™

The Epicenter contains a bass maximization circuit that accurately recreates and injects low frequency information back into the signal path. What that means in everyday terms is that The Epicenter will give more bass impact to your best compact discs or even your old tapes. US Patent #4,698,842


What’s the use of having good bass if you can’t control it? The Epicenter has a unique equalization circuit that contours the restored bass to your speaker system.

Dash Mount Control

The Epicenter is designed to be mounted anywhere in the vehicle, with the exception of the front bumper or radiator. It comes with a dash mountable control that allows you to enjoy the effects of The Epicenter without having to leave the drivers seat. The dash mount control also has a dual color LED indicator that can be rainforest green or sunshine amber. This LED will grow brighter as you add more bass or dimmer when you decrease it.

Bass Maximizer Indicator

Not only does The Epicenter Concert Series provide magic to your ears, but it also gives you some visual enjoyment as well. On the chassis of The Epicenter is a backlighted logo that flashes when the bass maximization circuit is activated. Special effects in your trunk!

PFM Subsonic Filter

This unique feature is legendary with many AudioControl fanatics for its ability to fine tune the bass response of any system. Why waste power on nasty subsonic information when your Programmable Frequency Match (PFM) filter can help you clean things up?

Bass Output Control

The Epicenter circuitry has the ability to produce large amounts of deep, mind shattering bass without damaging your speakers. The Bass Output Control circuit allows The Epicenter to maximize the bass output of any autosound audio system while restraining destructive bursts.

The Bass Master

This product is by far the best bass processor on the market. It produces bass by observing the true or fundamental note and drop it a few octaves down and wham you are hit with mind shattering lows. It also contains a Chip that you can build to suite your systems settings. Don't think twice if it's low bass you want, this is the product for you.

I ordered this epicenter a few months back, and its been pretty good so far. Its really easy to put in, and its small enough to put anywhere. I like to listen to the hard hitting bass songs and I though this would make them better but its actually better off with out it. On the other hand those songs that dont' have much bass it works great, so I would recommend this to anyone who likes to listen to rock, or spanish music that doesn't have much bass in there songs this would make it sound 10x better !

make every song have bass!

This is a great add on to anyone who wants every song they play to have bass. The bass knob makes it easy to control, and the LED gets brighter as you turn it up. The knob can be custom mounted in several locations. Audio Control is top of the line equipment. This unit is more expensive than other units that work similar, but this unit is the best, Audio Control pioneered bass restoration.

Epicenter cool technology

I bought this as I use an Ipod connected to my car stereo. The Ipods are notorious for not providing much bass. The little gadget lets me create bass on songs that really have none to start with. I noticed a few times that it creates bass that doesn't make sense, but I would say that 95% of the time it is accurate and quite good. A good purchase in my opinion.
