System/brand/model (ohm) loads vary greatly (2Ω - 16Ω) making it that much more of a useless statistic (but good for marketing). In quality systems, the drivers are usually better damped, both physically (surrounds/spiders) and mechanically (VC's/motors). The filter networks are typically more elaborate than a single cap/coil as well. The end result is usually a more balanced, neutral sound, at the expense of efficiency (quality vs. quantity). That said, not all "inefficient" loudspeakers are quality by default! YMMV.
i agree. i did not mean best efficiencey meant best sleaker. i heard the infinity a loooong time ago and was extremly impressed. but i was just stating that you need a lot more power to drive the infinities. i think the guy at work thought it was impressive that he was clipping a 200+ watt amp, but in reallity, the sound volume was less than what my klipsch were putting out with a 100 watt amp. i just could not believe his ears were not bleeding so i looked up the specs on his speakers.


i dont know about the high end speakers, but most lower end are not set up for bi-amp. mine are, although i dont consider mine low end. i bi-wire mine. i bought the 4 conductor 12ga wire from lowes, same stuff we use for pro sound. on each side, i connect 2 wires to + and -. then at the speaker i have 4 terminals, 2 foe the highs and 2 for the lows. i did not think this would make a difference but i could tell the highs were much clearer. the idea is that the high frequencies and lows use seperate cables.

2 amps bridged, use one amp for each side. or you could bi amp with 2 amps. left side of one for the highs, left side of the other for the lows.you would need a smaller amp for the highs as they dont handle as much power, unless you had a crossover that could reduce the level. i have not seen anyone bi-amp a home system. i thought about it at one time, but thought trying to balance the highs to the lows as far as power/volume would be a pain, plus the cost.
i bi-amp my PA, 2000 watts for the subs and 1200 for the top box. i could tri-amp if i had another crossover and we got another powered speaker for monitors.
