Can you provide any details Rick?

The arrays consist of eight ribbon tweeters and eight Scan-Speak 7" Revelator woofers. The subwoofers are powered with 1000-watt amps and move quite a bit of air (four 10" Scan-Speak Revelator woofers per sub). This was the most satisfying system of anything I've ever built and I hated to leave it in Boston

This particular system has a deluxe passive crossover with the option of being driven active / bi-amped with the owner's TacT gear. The arrays are configured for a 4-ohm load but also can be changed to 16-ohm if desired. The arrays are -3db@60hz and being a sealed box integrate very well with the subwoofers (also sealed).
