Curious as to how best set up my sub. I have the Vel cht-10, and have the ability to go from 40-120Hz for crossover, manually adjust the volume, and can also turn off the sub's cross completely. Also have the phase switch, 0 or 180. I have no ability to adjust the cross in my receiver, older model denon avr-1700, but am guessing it's probably 80Hz. After reading many posts, it seems that the best thing to do is crank the sub cross up to 140Hz, and let everything be controlled by the receiver. So if the receiver is set to 80, anything that falls below will roll into the sub automatically? I'm wondering that if the best method is attempting to avoid the sub's cross getting in the way, would I be better off just switching to subwoofer direct, bypassing the sub's cross entirely? Also, should I have my front and surrounds set to large or small? Small in the front, large for surrounds? Have PSB Stratus Silveri's, very nice near full range speakers up front, but don't want to have competing signals canceling or muddying each other out. I guess lastly, if I'm calibrating speaker levels to 75db, I read that you need to alter this level for the sub, as the signal doesn't come through very well at low frequencies on the SPL. What would be the recommended db level for the sub? One last thing, for some reason with my fronts now set to large, it seems my sub performs much better with the phase set to 180. Is this normal to have a sub want to be out of phase? Might it be because I have the fronts to large, and in phase I'm getting competing signals, thus out of phase seems to work better? Or maybe just a crap shoot as to which stereo rca input I'm using with my mono signal and cable? Sorry for all the questions. Any advise would be most welcome. Thanks very much. Hmm, I wouldn't mind if someone were able to link me to some sites that might go into good detail about all of the above. Not unwilling to learn without being spoonfed, just haven't been able to find good resources. Thanks again!
