Every time I try to put a sub into my 2 channel systems it does not integrate well - the sound never ends up being balanced and the bass seems to be over pronounced- I just tried again yesterday with a 568 and klipschorns - I used some citation 7.4 subs that have le14-1 drivers in them - I tried a bunch of crossover points and the best was at 35 hz, where the klipschorns naturally roll off - the bass was still to much even when I brought the levels low.
