slofuse1 Posted March 16, 2005 Share Posted March 16, 2005 I finally got the sub I wanted and need a little help. My receiver has 3 crossover frequencies to select from: 80, 100, 120 Hz. I believe the cornwalls work pretty well down to at least 50Hz. Does this mean I have the wrong receiver for the job?

To propertly set your sub and speakers you need to have a good test DVD and a sound pressure meter. Quote Link to comment Share on other sites More sharing options...
JJkizak Posted March 16, 2005 Share Posted March 16, 2005 The RSW-12 has it's own settings so it doesn't matter what you run into it. I just set mine to 80 and it's a done deal as long as you feed it a center channel or LFE channel. It also has outputs to feed the center channel or LFE channel somewhere else simultaneously if you are running two subs. JJK Quote Link to comment Share on other sites More sharing options...

jacksonbart Posted March 16, 2005 Share Posted March 16, 2005 "Does this mean I have the wrong receiver for the job?" Not at all, I agree with gcoker, set the cross over at 80, disable the low bypass on your sub. If you still want to send lower bass to the Cornwalls, set the 'LFE or LFE + Mains' to LFE+Mains. It you allow the RSW12 to handle everything below 80hz, you will be making your 1803 basically into a more powerful receiver, amp wise, because all of its power is being used for signals 80hz and above. That said after you spend some time on the forum you will come across many people have upgraded to a separate amp drive to their speakers and just use the receiver as a pre-amp, but enjoy what you have for now.

slofuse1 Posted March 17, 2005 Author Share Posted March 17, 2005 I really appreciate the advice. The really great thing about this forum is that you get to hear from numerous sources, all speaking from hard-won experience. Then you consolidate the info and come up with a solution that works for you. I ended up setting the crossover for 80Hz and tried it with and without the LFE enabled and at both polarity positions and it clearly worked best with the LFE disabled and the polarity at 0°. I'm a happy camper. Thanks again. 1972 Cornwall Mains, 1992 Forte II Surrounds; RC 3II Center; RSW-12 Sub; Denon 1803 Receiver Quote Link to comment Share on other sites More sharing options...
