Looking for all the audio techies and room correction gurus out there!

What I'm mostly looking for is to be enlightened, in simple terms, what is going on in my room and with my setup. And for possible tweaks and tips to try! smile I'm not very knowledgable with frequency graphs and eq and how this room correction stuff works.

Equipment: 5.2 setup

Pioneer Elite SC-57
Rotel RMB-1095

Axiom M80 v3
Axiom VP 160 v3
Axiom QS10
Cerwin Vega CMX-12 (x2)

I've taken some pictures of the basics within the MCACC software. I'm focused mainly on the symmetry setting with all these pics.

Everytime I run it, it EQ's it the same way. The system EQ's the front left and right the same, the surround left and and right the same and the center similar to the fronts but a little different.

Some questions...what's going on in the 63hz range? Why does it drop the 63hz range -6db on my front, left and center?

Anything you particularly notice?

Any observations, advice, tips or tricks to try...certain changes to eq manually, or anything?

All your input and observations or advice is much appreciated.

Just trying to educate myself without doing all the leg work of scouring the monster MCACC thread on avsforums wink

It's dropping the fronts by 6dB at 63Hz likely because your listening position is close to a back wall about 9 or 10 feet from the speakers. This is creating a standing wave. A 6dB drop means the fronts are being fed 1/4 power at 63Hz. I'll bet if you disengage that filter, it will go boom boom in your room.

I can give you tips but you won't like them:

- speakers need to come at least a quarter to a third of the way into the room
- sitting location needs to be at least 5 feet from the back wall
- speakers need to be 12 feet apart and 4 feet away from side walls
- sitting location needs to be 12 feet from the speakers

Basically you need a bigger room. Please don't hate me. smile

You could use some diffusion on your back wall, get a thick Persian rug for your floor...and ceiling. smile

Lol k thanks for the observations. The room is definitely not ideal

I actually have been turning off the eq with music and prefer it and with movies, prefer it on

Just wasnt sure if their was any MCACC adjustments that would make me go "wow"

You may want to try leaving all settings where MCACC found them for 500Hz and below. Above 500Hz, set all filters to flat (0).

You might want to listen to that for a while and see what you think.
