Looks similar to what I got with Genesis.

You can tailor it to any thing you prefer Mo. It has become very similar to REW.

A good guide is to follow REW guidelines. With A.R.C. for ultimate setup.

Not sure if it detects the downward slope, or if the smart guys at Anthem just recognize that response should naturally slope off. I haven't played with it a ton, but I'm pretty sure you can create your own house curve for ARC to correct to.

Hmmm...I don't think ARC forces a downward-tilting target curve. I think the software is deducing the designed response and attempting to maintain it. This is very smart!

Looking at it again, the target response curve doesn't match the profile of the M5 sound power. Why does ARC roll off the highs so much after 5KHz? Maybe it would sound even better if the roll off was more gradual. If you look at the M5 sound power curve, it starts rolling off at 200Hz by about 5dB per decade.

Then again, your room is not an anechoic chamber so getting the target curve to match the M5 sound power curve isn't right either. Ian has said the in-room curve shouldn't be flat. So what should the target curve look like?

Just remembered, 5KHz is the default filter cutoff for ARC. So everything you see beyond that is just natural in room response.

I see. It might be interesting to try and boost the response above 5KHz and see if your soundstage gets broader. Or not...just enjoy what you have. smile

According to what I have found in their studies {Anthem + N.R.C.} they came to the conclusion there isn't much use in EQing past that point 5KHz. {Can you tell I google too much info}

Lot's of people like to adjust to their preferences. Though It's about equal due to Mic. and human hearing.

One article I read from Anthem briefly discusses this topic, where I think they said you can go higher if you like, but their studies found the 5KHz to be most appropriate cutoff point.

Interesting about the 5KHz. I'm thinking if 5KHz is the supported max, then the mic is inaccurate above that point. So the rolloff you are seeing above 5KHz may not be accurate.

It'll go to 20khz if you override the default.

But is the mic accurate beyond 5? It may end up being very directional and hence the reason for the limp response.
