Help with AVR Speaker settings

[frodobalboa]

Hi Guys,

Newbie question below. I recently upgraded my old Yamaha HTS-5730 HTIB with an Onkyo SR605 and JBL Venue Series speakers ("Voice": Center, "Monitor": L-R and Surround L-R). I also got a Dayton 10" powered sub. I made use of the Audyssey mic to calibrate my speaker settings. This is what I see in terms of Speaker settings -

Center : 60Hz
Front L-R: 100 Hz
Surround: 80Hz
Subwoofer: 100Hz

I have been reading a lot of articles here as well as on AVS Forum and I am thoroughly confused! I am having an information overload! I set the Crossover freq settings on my Sub to max (180Hz) and my Gain is about 1/2 way up.
My question is - are my settings OK? I am having a nagging feeling that I am not getting the best sound. I have placed my sub at a left corner with respect to my listening area (this is about 2-3 ft from the other speakers). All my other speakers sit on my big Ikea Entertainment Unit, equidistant from each other. I havent yet placed the surround speakers behind the listening area, but will do so soon. The receiver shows most of the speaker distance levels as 9ft and the sub as 12 ft (using Audyssey). My living room (this is where I have the HT setup) dimensions are - 15'(L)x20'(W)x10'(H). My primary AV source is my new PS3 BD player or my HD cable box.

Any and all help will be greatly appreciated.

Thanks in advance.

Audyssey and other auto-setup routines attempt to measure the lowest frequency the speakers are capable of reproducing and use that to determine the xover frequency. They are mostly fairly accurate but often choose to set the speakers to Large instead of Small. The settings could be ok but one thing that is suspect in my mind is the xover frequency of 100 Hz for the front speakers. It is extremely rare that the front speakers are not as capable as the center or surrounds.

You could look at the published frequency response for each of the speakers and adjust the xover frequency based on what the specs say is the F3 (-3 dB point) of the speakers. In general, 80 Hz is appropriate for all channels unless you have some speakers that cannot reproduce frequencies below 100 - 120 Hz accurately (like surround speakers).

Thanks for the info MDS. I checked my speakers' FR and my center channel speaker has an FR of 70 Hz and the remaining speakers have an FR of 68 Hz. I have now set the xover freq to 80 Hz to all the speakers including my sub. I hope these settings are correct?

Those settings sound good. Make sure all speakers are set to "SMALL" and enjoy the new gear.

The independent crossover settings can be useful for configurations where the surround channels only play down to 100-120 Hz or if you have full range mains that play down to 30-40 Hz but neither is the case with your new speakers.
