Duplicate room correction

No, this isn’t in relation to my "critical" stereo system. I’m talking here about my home theater, which is built around a higher-end Marantz AVR that uses the Audessey room-correction technology. Not exactly Dirac or Anthem, but I’m still giving it a chance.

What I’d really like to find out is an authoritative listing of just which parameters any of these RC DSPs actually adjust. That would answer a lot of questions about how and when to use them to the greatest effect..

OP:  What amp do you have? An Anthem??

Thanks, Erik.  What you say makes sense.  In fact, I've been trying for some time to determine just which parameters the amp's embedded room-correction SW actually adjusts.

Hey, good questions!

Room correction software all have an "opinion" about what the final outcome should be. The software in the sub and the software in your amp could very well come to different conclusions about what everything should sound like.

I’d keep it simple and let your amp lead, and the reason is that it will want to do more. Not only will it do EQ but also delay, levels, crossover settings and speaker matching.  Leave your sub with the highest possible crossover frequency so the amp has the most flexibility.

Subwoofer’s usually only adjust EQ for themselves.

Having said this, placement is important. Check the AM Acoustics Room mode simulator for the best placement locations for your speakers and listening location before doing any sort of calibration.
