[QUOTE="kiwijunglist, post: 1134935, member: 76888"] It depends on the speaker and the subs capability. I think crossover at 80 should be fine. Audessy will analyse your speakers and suggest a cross over freq. You could probably do anything between 60 and 100. Ideally the cross over should be atleast 10hz adove the -3db point and you should set the cross over the same for your front and Centre. Setting it even higher will ease the load on the speakers and allow them to perform better at other freq (when they are pushed hard). Setting the cross over above 120 is bad because you start to localize sound above this frequency. So instead of the sound coming from the Centre you will hear part of it coming from wherever the subwoofer is placed. My current subwoofer isn't great and since all my speakers are pretty huge and my rear speakers are towers I'm currently running them all full range but when i get a better sub I'll cross them at 50 or 80 (ideally I'd choose 60 but it's not an available on my pioneer). Rythmik is another sub brand similar to svs. There is also hsu and sunfire (they make small sized subs). These brands typically have good performance per dollar. If you can't get these brands then maybe velodyne. You could also get 2x second hand subs. [/QUOTE]
