Just bought AVR with 2EQ - can I run it, then manually calibrate my sub?

I'm looking forward to answers to this question too! I'm in the same boat. I do notice that Audyssey does set the distance to the sub, which turns out greater than the actual distance, and I've learned to keep the calculated distance, as the increase has something to do with the delay in the sub circuitry itself (don't quote me on that).

I generally am constantly tweaking the gain control knob on the sub depending what I'm listening to, for BR, or TV content, or regular DVD, it all seems to change the 'loudness' of the sub and I am always tweaking the gain to where I want it.

Again, I look foward to learning any more tweaks I can do in the Onkyo setup for the sub.

thanks,
Todd

The 515 will set the distance and level for the sub, it just won't "equalize" it. It will set the crossover for the other speakers and send anything below that to the sub, so in effect it's also setting the crossover. My 616 is my 4th or 5th receiver with auto setup and they've all had these capabilities. Before running auto setup make sure the sub is on, turn the crossover control to it's maximum, and the volume knob about halfway. When the auto setup is done check the subwoofer level selected by the receiver. If it's at or near it's lowest setting (-15db on my Onkyo) that means it couldn't turn the sub level down far enough. Turn the volume knob on the sub down and rerun the auto setup until the receiver comes up with something around 0db for the subwoofer level.

If your receiver auto setup decides your speakers are large and/or sets them to small but, in your opinion, doesn't set the crossover low enough you can manually change them to small or raise their crossover level as desired without affecting the calibration.

I just let the receiver do it's thing and rerun if the sub level is at it's lowest setting, then change all my speakers to small and set their crossover to 80hz. If your using small satellite speakers you might want to try 100-120 hz for the crossover. I also usually bump the auto-selected sub level a few db, just as a matter of personal preference.

Thanks Steve, I will do that tonight!

You guys would be well served by reviewing the Audyssey 101/FAQ guide linked in my sig which is an accumulation of the main questions asked in the main Audyssey thread.

The "AVR" will adjust the volume of the speaker to calibrate with a 75db test tone to include computing the distance and recommended crossover of the speaker. Audyssey will attempt to flatten out across the entire frequency spectrum (in the 515's case from about 65Hz and higher).

Hi, first of all in order to understand what 2EQ does not do to the sub channel you need to be familiar with the meaning of "flat frequency response". Read on please.

I'm afraid there is nothing in the Onkyo 515 that you could tweak manually to get a uniform frequency curve in the sub channel. Is it possible for you to swap your 515 for another AVR with at least MultEQ with your dealer?
