Ok...I have a little steam to blow off here and I'd like to blow it off here on HTF. From what I know Yamaha receivers have a built in (set/non adjustable) crossover between speakers and sub at 90hz. So as the crossover story goes, when all speakers are set to small, any frequency/information below 90 hz is sent to the sub. Not hard to understand, is it?. If that is the case then answer me this. I took out my AVIA ( for those who don't know what it is, do a search) and calibrated my system. I decided to do the 200-20 HZ sweep to see if my recent room adjustments had ridden me of some of the humps (it worked somewhat). Then I decided to do an experiment. I disconnected the RCA sub cable from my PW2200 and see what frequency my main speakers (Paradigm M7v2s) stopped at. You would think with them set to small( and they are I checked) that they would stop at around 90 hz...hence the crossover. But they don't at all. A decent audible sound was still coming out at 42.5 hz, and 38.5 hz. But wouldn't that be transferred to the subwoofer. Help me out here....am I missing something when it comes to the crossover in my receiver? Thanks in advance, Ryan P ------------------ Oops, I dropped my eardrums. Could you pick them up for me?
