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
