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.

Audio control epicenter

The Epicenter will beat your subs better than OJ beating a charge. If you love your audio, this is a must have. I was skeptic about shelling out the cash for it but everyone keeps saying how much the love the strong clean bass. Don't waste your money on cheap crap, get the epicenter and trust me u won't be disappointed.

Works great

Bought this product 3 years ago and haven't had any problems. Extremely durable but can be difficult to tune.

Low bass Magic

If u Lov Low Bass. Than this is it. I own this product, and I love it. I recommend it to serious low-end bass freaks, (especially if u listen to old school R&B & rock… 808’s wasn’t invented then!) Para-bass knobs will take some time figuring out. Cons will put some serious strain on subs, amp (can drive Class D amps into clipping fast @ hi levels) And Current Draw (can make lights flicker 2 much.)
para-bass is like a parametric e.q. so Turing them counter clock wise, will produce lower tones. Try playing test tones on your system 1st. & if u can’t hit the notes between 20 – 45 hz then your system isn’t going to have the best results with this product… this thing seems to be centered @ 20 – 35 hz notes. Purest may not like the sound this thing makes synthetic sounding unnaturally low bass… it will process between 50 – 95hz lowering them 30 hz i.e. 50zh natural will get dropped to 20 hz. With the epicenter… if u don’t have test tones get them hear free

Bass lovers best friend...... mostly.

I purchased this because I wanted to compare it to another Bass Restorer that I own thinking that it would not reduce bass in bass heavy songs like the other one did, but it still did. Although not quite as much as the other one. This is a better product than the less expensive ones, and is priced more because of that fact. If you listen to older music or rock, then this exponentially increases bass, and even does so with some rap/hip hop/dance music. Overall, it's better than other bass restorers, and if you listen to older music, it's a must have piece of equipment. I have it hooked up to 2 10" JL W3V3'S and it makes them DANCE BIG TIME. Got a 13W7 on the way, we will see how that works out with it.

Great bassssssss!

I bought it not thinking it would enhance my bass as much as it did. With a system as large as mine it may have slightly been an overkill. I would use it on a system where you think you squeeze out a little more bass without rebuilding your whole system.

If you want to go low, here you go

The epicenter was just the answer I needed to my troubles with not being able to reproduce low frequencies. I had my box for thrre IDQ 12DVC's built by the current Isaca World champion in the pro class at 600-1000. he spec tuned it for SQ, and it really sounds great but I did'nt get the low end that I wanted. So after about a year of that, I installed an epicenter for the subs and OMG!!! It is noticable to hear the one octave difference and being able to control SQ and SPL is a great feature. Overall I think this is the best subsonic filter on the market.
