Kick up the bass

You like all the bumpin' bass you hear in hip hop, rap, and EDM? Well you can put that deep, biting bass into any kind of music — from classical, jazz, and rock to folk and Tejano — with an AudioControl Epicenter bass restoration processor. Most factory radios dial down bass response to protect flimsy speakers, so when you do add a subwoofer, there's no bass to play. The Epicenter will bring it back.

Kick up the bass

You like all the bumpin' bass you hear in hip hop, rap, and EDM? Well you can put that deep, biting bass into any kind of music — from classical, jazz, and rock to folk and Tejano — with an AudioControl Epicenter bass restoration processor. Most factory radios dial down bass response to protect flimsy speakers, so when you do add a subwoofer, there's no bass to play. The Epicenter will bring it back.

AudioControl's legendary Epicenter bass processor maximizes the low-frequency power and punch of your bass system, whether it's a simple powered bass tube or a full-blown competition setup. Simply install this processor between your receiver and your amplifiers or crossovers, and you'll finally be able to hear all the good bass you've been missing. An included wired remote lets you control the amount of thump from the front seat.

How does it do it?

Sophisticated processing analyzes the incoming signal and synthesizes low-bass fundamental tones, increasing bass response tremendously. The Epicenter connects to any receiver with preamp outputs — its balanced inputs will reject noise from your car's electrical system. A subsonic filter removes extreme low frequencies from your signal so your amps and subs will play more efficiently, while a single band ParaBass equalizer lets you fine-tune the bass tone.

Product Research

Features

Bass Restoration: Rather than simply turning up the bass, the patented bass restoration circuit takes a full range input signal and measures the upper harmonics of the bass frequency range to determine what frequencies have been lost during the recording process, then correctly restores the missing bass information. The remote rotary knob allows you to control how much bass is restored to the system. A full range signal is output from the Epicenter that can feed a full range amp, a subwoofer amp (with built-in crossover), or an outboard crossover.

Para-Bass: Para-Bass is a single band, parametric equalizer for the bass output. The center frequency is continuously variable from 27 Hz to 63 Hz. The width of the band is also adjustable.

Bass Maximization: The Bass Maximization circuit allows The Epicenter to maximize the bass output of any system while restraining destructive bursts, which can damage speakers. the 5.0 volt factory setting can be changed to 2.5, 7.5, or 10 volts if the amplifier and speakers can handle it.

Remote: The bass restoration level is adjusted using the included wired remote. The remote is designed to be dash mounted, within reach of the driver; it can be mounted under the dash with the supplied bracket, or the bracket can be removed and the knob and LED can be custom mounted through the dash. Dimensions:

  • Width: 2.557"
  • Height: 1.489"
  • Depth: 1.824" (2.448" including knob)

Subsonic Filter: The subsonic filter crossover point is 33 Hz; it's governed by a replaceable chip, so it can be changed to 20, 25, 30, 35, 40, or 45 Hz.

Balanced Inputs: Using the balanced differential input circuit cancels noise picked up in the transmission line between the Epicenter and the the source unit. The inputs can be set to balanced or unbalanced if needed.

Ground Isolation: The power supply ground is switchable, in case of ground loop noise. The factory position is fully isolated (typically the best choice), but can be changed to Ground or 200Ω.

Terminal Block: The power/ground/remote terminal is removable; the wiring is attached to the block, then the block is plugged into the Epicenter.

Specifications:

  • Maximum Input Level: 15 volts RMS
  • Maximum Output Level: 9.5 volts RMS/13 volts peak
  • Frequency response: 10 Hz-100 kHz;±1dB
  • THD: 0.003%
  • S/N Ratio: 130dB
  • Balanced Input Noise Rejection: >60 dB
  • Input Impedance: 10 kΩ
  • Output Impedance: 150 ohms

Q
Is the subsonic filter only active when the Epicenter is actually turned on?
[ T-Bone  Jan 24, 2018 ]

A
Yes that's correct.
[ Sixtus Jn  Jan 24, 2018 ]

The subsonic filter is on all the time even if the Epicenter's processing is not being used. The PFM subsonic filter shipped with the Epicenter is set at 33 Hz. Sounds below 33 Hz will still play but at a decreasing volume as lower the sound . You can buy PFM filter chips from Audiocontrol directly by going to the AC website, clicking on "CAR" at the top, scroll down to "ACCESSORIES", and then click on "MODULES", and finally clicking on the "Buy Now" link on the blue line at the top. You have to pick the 18 dB/Octave choice for the Epicenter. The 24 dB/octave choice is for AC crossovers. Frequencies from 15 Hz and up are available and cost $10 each plus S+H.

Q
Does this product help to add the missing bass to the car door speakers? Only reason im looking at this is to improve my speakers. I have two 12 subs. I dont need sub bass. I want speaker bass.

You want more bass out of your door speakers? What crossover is used for them? Are they big enough to produce what you're looking for? The Epicenter adds bass back into music that may have been removed when converted to MP3 or during studio recording, etc. Most of what it adds to the music is in the sub bass range. This product doesn't necessarily add more volume throughout the sub bass range, only at the frequencies where it's been taken out. Audiocontrol's website has a great explanation of what it does and at what frequencies.
[ Charlie  Aug 23, 2017 ]
A
Not unless your door speakers are hooked up to your power amp, in which case I would recommend an LQ7 or LQ9 it lets you control the sound all around to your preference.
[ Antonio  Aug 22, 2017 ]
A
No, this will not get more bass into your door speakers. You are looking for more midbass, which is typically between 50-250 Hz. The Epicenter works its magic mostly under 50Hz. What you need is dedicated midbass speakers that are at least 6-1/2 inches in diameter or larger and have plenty of amplifier wattage powering them to get good midbass out of the door locations. There are other tricks to improve your midbass like adding sound damping materials to the doors and sealing all holes in the door. Search Youtube for videos on how to improve your midbass. Here are a couple of videos to get you started: 1. https://youtu.be/S7WKCFHGwRY 2. https://youtu.be/h3EXuHlBy4M Hope this helps.

Q
Does the Epicenter also act as the 9.5V RMS line driver or is it necessary to play an Overdrive in front of the Epicenter?
[ Mbrogz3000  Mar 31, 2017 ]
1 answer
A
The Epicenter can provide up to a 9.5volt signal output so, an external line drivers is not required. I hope that helps. My Bio: https://www.crutchfield.com/Support/Bio.aspx?bio=5

Q
Where do I connect the epicenter's rca's to the Headunit.. Sub out or rear out "full range".?? Or do I connect them on sub out and adjust the Headunit's settings to full range. Or is it the other way around. Please help.
[ Edgar  Jan 08, 2016 ]
1 answer
A
Edgar, I haven't hooked it up as of yet. The instructions note that you should hook it to the full range output before any crossovers. If your sub amp has an internal crossover, then I would set the head unit output to full range and make the frequency cut at the amp. I hope this helps. Thanks,
[ John  Jan 08, 2016 ]
