They either need a crossover hanging on the end of the power amp or an active filter between the pre and power amps, aren both likely to ruin the sound from any carefully chosen system?
A2. Agreed, most do. However, REL sub-bass systems use the unique REL ABC, which circumvents this problem completely. The ABC is part of the electronics of the sub-bass system and as such does not interfere with the main signal route between pre amp, power amp and the speakers of the main system. For hi-fi use, the signal for the REL is taken at high level via the main speaker terminals on the main amplifier. The impedance of the REL’s high level input (100,000 ohms) has no adverse effect on the main system whatsoever.
