This was a bi-amplified powered studio monitor speaker system that used a new 771B Bi-amplifier with 30 watts for the high frequency compression driver and a 60 watt woofer.

There are built-in electronic crossovers that split the signal frequency and also will route the lows and highs to the amplifiers. There are also two different transducers. A three-way or tri-amplified powered speaker system routes the low, mids and highs to the amplifiers and transducers.
