Bass Restoration Device • Low Output Impedance • High Input Impedance • Flat Frequency Response • High Output Voltages • Excellent Signal-to-Noise Ratio • Panel mount RCAs
Have you ever listened to a song and thought "I know when I saw them live there was more bass than there is in my car"? The cause of this is due to a loss in the transfer from the live performance to recording. To restore that original live experience the cbr uses a special technology that rebuilds and conditions that lost bass information.
Unlike competitive products that must have a full range (20Hz to 20kHz) input signal the cbr can achieve restoration with a signal filtered as low as 120Hz. This means that you use a low pass signal from a head unit or other processor device so long as the filter point is 120Hz or higher.
The remote control unit on the cbr provides complete adjustment over the output level of the bass as well as a separate knob that controls the subsonic filter frequency. This is helpful in tuning the cbr to your specific subwoofer system, vehicle and listening preference.

the perfect bass enhancer
the CBR is light weight, sleek in design and does what its supposed to. the controls and labels make it very simple to install. i like the clipping indicator LED's and the wired remote adds more option in tuning

Cache CBR Bass Restoration Processor
When we bought this I compared it to the Epicenter. The numbers were all within a few specs of the other, and though I hadn't heard too much about Cache, I thought I would give it a try. A year and a half later, I have no regrets! The CBR does what it was designed to....restore bass that may be lackluster or even missing from the recording process. Love the looks of the all business design that Cache employs. Though the Epicenter is a great item, don't get caught up with the flash of it or similar products. Cache makes very well designed audio gear for the automotive environment.
