can anyone explain me what is the whole philosphy of 6.5's speakers and their separate tweeters and woofers? and then the set has something with it i think a crossover? does these speakers work the same way as 6x9's would do? what would be better to go for if i want the hammond's bass string notes to come out clear and effective, a sub or pair of front component speakers? i got pioneer 80rms 6x9s in the back. what can be good speakers which can come around $200? as far as i know, midbass is not actually the thump but its the bass guitar notes in the song. please correct me on anything if i am wrong. thanks in advance.
