I have some extra space in my amp rack since I switched from a Zapco studio 100 to a 50 for my highs. These are kinda cheap and the summit white model matches my Zapcos so I was thinking about picking one up just for fun to see what its got. I actually am really happy with how my sub-bass sounds but I just wanted to see if this thing had any special juju. Anybody ever play with one?

Actually, it’s nothing of the sort. What it does do is SYNTHESIZE low bass signal by producing half-tones based on the recording’s content in the 50-100Hz octave (IIRC).

Think of it as the exact opposite of those Sunfire “True Subwoofer” quote-unquote subwoofers, which take signals from the lowest octave and double them (i.e. produce a loud 50Hz tone based on a 25Hz input signal) to give the illusion of low bass from a small package.

Is it a good thing? Well, I have one* in my home system and while it’s often off, it does do a specacular job of restoring bass to older recordings mastered before it was relatively common for audio systems to be capable of low-distortion deep bass. It's useful enough that I don't expect it to leave my main rig in the foreseeable future. However, I've no interest in one for my car, where it would just create distortion most of the time.

*The actual component is not technically an Epicenter but an AudioControl Phase Coupled Activator Series 3, which is in car-fi terms an Epicenter and 24XS combined in one chassis with a 120V power supply.
