What electronics are you going to use to drive the speakers?I have lived with a sub/sat system(the Baby Grand system) from a company called Aura Sound,for the past 2 years.They are the original patent holders for the Line Source Tweeter(Lineaum)which was used by several companies with excellent results.The speaker uses a proprietary 3"woofer with extra long throw surround & the line source tweeter.I drive them with a 100 wpc Pioneer Elite & they absolutely ROCK!Great sub/sat systems can be had from:Quad(the "Lite"system)or KEF but I think the most effecient system is probably from Paradigm.Hope this helps.
