Description
"The Wisdom Audio amplifier/speaker system is designed to take advantage of a fact that has hitherto been understood only by a relatively small number of audiophiles: speakers sound better when they are driven directly by dedicated, high quality amplifiers. You might think that you have done so in the past. After all, you connected your receiver or amplifier directly to the loudspeaker cabinet, using high quality wire. But in almost all cases, that connection led to a passive crossover network within the speaker cabinet, made up of resistors, capacitors and coils of wire called inductors. The passive crossover had the job of splitting up the signal to the woofer, midrange, and tweeter inside the cabinet. By design, it created a complex, reactive circuit between the amplifier and the drivers that actually make the music. The Wisdom Audio approach does not suffer from this compromise. The SC-1 is an active (not passive) crossover that divides the music signal while still at a preamplifier level. It can do so with far greater accuracy and consistency than can passive components in a speaker box, with their inevitable production tolerances. These separate signals are then routed to dedicated amplifiers which need work with only a portion of the audible range. In the case of the SA-3 amplifier channels, they need handle only the bass; the midrange and treble are routed to a separate amplifier of your choosing that drives the planar magnetic panels. "
