[QUOTE="gbyleveldt, post: 45891, member: 122"] They should be decent enough, I've not personally used them though. Looking at the specs and considering the application, they should be great. I see a reference is made above to getting 25WRMS bridge into 4R. I cannot stress enough that this is a bad idea. When you have a 4R load bridged, each amp sees 2R. Very few amps can drive these low loads properly, not considering the fact that distortion goes though the roof. Ludo's idea of going active is not a bad one, as passive XO design can bring the impedance of a speaker system to very low levels. This will destroy your new project in a flash. Have you considered the battery system for the project? Split rail supplies are not too out of this world, if you consider that two 12V batteries in series could give a lot of juice. I understand you don't want it to be heavy, but how heavy is not heavy? Is this thing portable enough to have on your shoulder while doing MC Hammer moves or is it ok to wheigh as much as a 20l coolerbox filled with beers? [/QUOTE]
