see, the best part about SQ, is that it is not as subjective as you think.
SQ does not mean SQ IMO. your oppinion of a good sounding stereo is not sound quality. its your oppinion. and just because you think that a larger diamater speaker can play more of the frequency spectrum and get louder means nothing because that is a stereotype and simply false. it has been proven false hundreds of times.
loud is also something that has absolutly nothing to do with sound quality. just because a stereo gets loud while doing all this jazz "sub-bass, mid-bass, vocals, mid-range, clear, crisp, thump" means nothong.
because i dont see stereo image, or sound stage - the two most important things in sq. go read a iasca sq rule book then get back to me. there are a lot more things in real sq that you are completly missing.
and fyi, the loudest a sq car needs to be on the TL is a 140 for a burp. otherwise i doubt they are any louder than a 130 durring auditions.
