People with rm7200 setups come chat

I've had my rm7200's and H/K avr230 setup now for a month or two. Couple questions to others with the rm7200's. Where do you have the volume on the back of the sub set to. Say if 50% was 12 o'clock, about what is yours set at. Also when I adjust the other knob (crossover frequency I think), I don't notice a difference in sound(I have my speakers setup the "Polk way", with the fronts connected to the sub..). I'm trying to synchronize the sub with the rest of the speakers for mostly H/T use, so the bass sounds appropriate with the sound and volume of the other speakers. I know the receiver and other system components will have somewhat of an effect on these topics but i'm just curious how other people are running they're systems. Also I've read on here of other 7200 people looking to get a rear center for 6.1 by upgrading they're center, then switching the old one to the back. If I find a good deal on a step up center I may consider this if it will still be properly timbre matched for the most part. Last question, what volume do you guys usually watch dvd's at? (I know receiver's etc have an effect but just curious). I usually watch mine at about -25. Thanks for any comments or suggestions, greatly appreciated.

Anything?

Set the sub-woofer level by playing a CD that you feel has well recorded bass information, something where the sound engineers tried to get a realistic quality to the way bass sounds, not exaggerated, but well balanced and defined. Adjust the sub-woofer level until you can just detect the sub-woofer as a separate sound source. Then reduce the sub-woofer level a small amount, you want to find the point where a slight increase means you can detect the sub-woofer as an isolated sound source and a slight reduction causes the sub-woofer to "disappear". Someone who is not familiar with your system should never suspect that you have a sub-woofer, all of the sounds should seem to be coming from the satellites. Setting your sub-woofer level this way will improve bass clarity and definition, whenever any frequency range is elevated that soon becomes the "0" point, to our hearing, and all of the other frequencies are reduced by the boosted amount. When your system treats all frequencies equally you can begin hearing all of the subtle details that makes a "high fidelity" system ultimately satisfying.
I hope this is helpful information.

I prefer to use a disc of test tones. If you set the sub so the tones are the same level below and above the crossover point you will get the same result and I find it a little easier than using a music disc. Of course you need to get the disc and a spl meter helps too.

As far as slow replies to this question: I have posted questions on the S series and the RT series. The responses to the S series were much slower and not quite as helpful, while the RT questions have had quick and very helpful replies. I think the reason is that people who are serious enough to be spending time on this board tend to have RT or LSI, people with rm or S series usually are not hanging around this board. Don't let the slow responce put you off, the people here are very helpful.

Awesome help guys. Sorry I just have the RM7200's, it's my first real surround setup. Maybe sometime I'll start upgrading by getting a better center and using the old one as a rear center for 6.1. As far as the bass tuning, it sounds like very good advice and makes sense. I've mainly been watching movies on my setup and I'm just trying to figure out where the sub volume should be at so it sounds good with the rest of the speakers, not too loud and boomy but up enough to give appropriate bass at the right times. I'll have to try a couple music cd's and see if I can get a test tone disc, as well as an SPL meter to adjust it right. Kinda an off topic question but right now I'm using my xbox as a cd/dvd player, with the monster cable setup that uses the lightwave 100x fiber optic cable etc. so you can get dolby digital sound from the xbox. Question is as far as sound goes, would I get significantly better sound through a normal dvd player(as opposed to the xbox) with a straight fiber optic cable? Thanks for the help, really nice site here.
