I just remember a few threads about this driver is all. One guy even wanted 4 of them. As Frank pointed out when you consider the price difference for every one extremis you would have two of these. Like the thread title says its just a FYI.
i bet it would beat anything that that you could pick up at best buy for those small 2.1 systems, add on some of their full ranges and you got one hell of a PC gaming system.
Parts Express has a 15w/channel Sonic Impact Class T (Tripath) amplifier that can power some satellites. Run the RCAs into the sub amp first, and then into the T-amp. You may have to do a search for it. You could have one spicy meatball of a setup with the Tang Band sub and a pair of Super Elf kits from CSS.
