Optimization is the game.

Hello All,
Im looking for an optimization question ... being the beginner I am it took me three days just to figure out how to get sound to come from my speakers. The first bleep from the sound test was as beautiful as an orchesteral symphony, I was looking for any confirmation of sound production. Now that I have heard sound I wish to optimize it.
My set up includes two RM7300's as the front speakers and a RM7302 as the center with two RM6901s for the surrounds. My receiver a Denon 2807 (The release date was seemingly delayed by a month up here north) stated after the sound tests with the nifty little mic that the cross over frequency is a terrible 150 hz for the RM7300 and 90 hz for the RM7302. This doesnt make sense as they are the same design except the logo is in the horizontal position on he center speaker (RM7302) and on the Polk specs on this website they are spec'd at 65 hx-26kz (overall frequency response) and Lower -3 db response 90 hz (not sure what lower -3db means though). The smaller rears have an overall frequency of 95 hz - 24khz and Lower -3db limit of 130 hz. The frequency range of the fronts according to the specs would lead me to believe that it would be ok to put the cross over to my sub, Velodyne DPS 12, at 80 hz but the sound analysis procedure from my Denon 2807 would lead to believe something else. Please help, I dont want my system to sound like a tin can! Thanks everyone.
Best regards, zx_toth

Playing with the settings is half the fun!! Don't be gun-shy about trying different crossover settings untill you find the one that works the best for your ears. Start with 80Hz and go from there.
While your at it...CALIBRATE!! Get yer azz over to Radio Shack and pick up an SPL Meter and set all of the speakers o the same output. Yes I know your receiver has a whiz-bang mic/set-up program, but gettting your meat hooks wrapped around a meter and doing it yourself will yield better results.
Now off your tired ol' beer drinkin' **** and get with the program!
BTW, Welcome to the Forum!:D -
Wow, Frank has a "real" way with words. I agree the auto setup is probably not perfect, however it is idiot proof usually. If you have any questions no mater how big, small, or stupid don't be shy to ask. This is THE best site on the internet to learn about optimizing your music. I do not have much experience with the equipment you have posted but i'll bet someone else here does. BTW welcom to the Club!Harman Kardon AVR635
