Room Correction... I like it!

[slartibartfast]

We're definitely monitoring threads and jump in when we can! We've got engineers, product managers, and executives all watching the forum, though they can't always get involved in threads, they love reading what you have to say.

I responded to your question about the Amp last week the team is working on updating it with that firmware version. It should be out really soon, but I'll check in with the team working on that to confirm.

The announcement today didn't mention Auto Timing Alignment though. This was in the Amp Pro and the Ultra firmware a couple of weeks ago.

It's starting to roll out this week and will continue to roll out for all products over the next couple weeks.

kinda insane though - +9.5dB in the 40Hz region? do you have a subwoofer in your setup?

Interesting... I got more or less the same boost in the 40Hz region, almost as RC is trying to coompensate for a deep. I have used DSPeaker in its various incarnations for years, and it neever touched the 40Hz region... But, I must say that Wiim RC final result seems pretty good despite what I think of the way it handles bass

Thanks, I’m looking forward to the release of independent peq rc.

To the room correction experts:
Is it sufficient to correct left and right together or does correcting both channels independently produce significantly better results?

Best to have indepedant PEQ for each speaker, my L/R are different in response so a unified PEQ for a pair wouldn't really work. Used REW to plot each speakers response.

It all depends. As rccarguy pointed out, the less symmetric your speaker setup is in your room, the more benefits could potentially be gained from independent channel EQ.

Independent peq rc not even available on wiim.

No, but you can use REW to generate the filters then manually input them. I still want to know the correct way to get correct response from a subwoofer with independent PEQ.

Rew is complicated thing to use. I just want point click and let the software does its magic. You also need umik 1 or Dayton mic.

You mean phase? I run sweeps adjusting phase on sub, then compare each response seeing what's the best response. Once you get that as a starting point then apply PEQ corrections. Ideally you want seperate left, right, and subwoofer PEQ filters. If the wiim only does combines Left, Right and subwoofer that's more tricky, probably wouldn't want to apply corrections on one where it could also effect the other, ie if you set 80hz high pass, I'd try and not correct around the 80hz area as it'll effect both speakers and sub.

Wonder how this story will be continued? Independent EQ for every chassis? For two, three, four way or coaxial speakers? ;-)

I was thinking more about the amplitude. When I measure L+sub and R+sub and correct them independently I get too much bass when L+R+sub are played together. I think it is because the left and right channels are perfectly correlated in the sub woofer resulting in an extra 3dB.

 

[rccarguy]

One option is to use off board subwoofer correction. If you have the option of correcting L/R but leaving the subwoofer output unaltered? Then you can buy antimode/minidsp or a subwoofer with built in subwoofer correction.

Or does L/R always effect subwoofer pre out?

This is not the future, but simply reality with fully digitally controlled active speakers like e.g. KEF LS60, KEF LS50 Wireless II and others.

Obviously, you cannot apply per-driver EQ to a passive speaker. You can just EQ the total output.

 

[LucAce]

Rew is complicated thing to use.

No, it isn't. A simple measurement isn't rocket science. You just have to take a little time.

And the great thing is: it could even be worth it.

A measurement microphone is cheaper than constantly changing the hi-fi hardware, which is often not the real problem.

It was not about the technic. It was about expectations ;-)

In that case you forgot to mention fresh coffee being brewed by RC, but are totally right otherwise.
