Hello I have a question for Teil owners that may be monitoring this old thread. I recently came into possession of a set of Teil CS3a's along with Conrad Johnson amplifiers. So far I'm pleased with the sound, but in the mix of equipment I brought home was a small black box marked 'Teil Bass Equalizer' Does anyone have any experience with this gizmo or know exactly what it's supposed to do? I hook it up and I can't tell if it does anything.
