hi, i recently bought a great set of speakers off of craigslist. they are ads L1230 which i got for $110. these are the best speakers i've ever owned. i just upgraded my receiver from a ten year old sony str-de525 to a denon avr-1312. i also have an old mirage ps-10 sub. my question is, can i use these ads speakers as fronts in a surround setup? i have an older (best buy $100) jbl center channel speaker which i previously used with some older smaller front speakers. from what i've read the front three speakers are supposed to be matched. would a better center channel speaker help with this setup or should i just use the ads speakers for two channel music listening? thanks!
