What are the sonic benefits to improving phase?

[tjcinnamon]

What is the sonic benefit of improving phase response? I’ve got a lot of experiencing EQ’ing with a miniDSP for improving/flattening frequency response but I have no clue what improving phase response does.

Also, is it only good to do below a certain frequency?

Do I measure from my seated position?

Is it only able to be “manually” manipulated with a convolution file?

Improving the relative phase response between the Left and Right front main speakers can be a huge contributor toward sharpening your Soundstage and Imaging.

There are those who will advise doing that only below your room's transition frequency, or below 500 Hz or so. That applies if your room is fairly live. If the front of your room very dead, like mine, and you have highly directive speakers (open baffle, panel, horn), you can EQ your room full range.

For room correction, always measure from the Listening Position.

Dirac Live performs phase correction, impulse response correction, and amplitude correction, and is an amazing product.

I had Dirac and it was nice but not flexiblle enough in the AVR I had. My room is very dead up front. So I can/do correct full range.

I’m a fan of Audysseys dynamic EQ. However, I just sold my AVR with Dirac to a friend. We set it up and it was very good in his room.

I want to upgrade to a Denon/Marantz higher model so I have to option for both.

Cool. The only thing I don't care for about Dynamic EQ is that it sometimes seemed to shift images back & forth with volume changes.. Glad you like it, though.

Good luck with your journey!

Thanks much for the very kind words.

I’m now running LR Bypass and it’s giving me a super flat response. So I guess I was eq’ing unnecessarily. I am still running DEQ but I is not EQ’ing, just doing it’s boost.

On top of the improved left & right speaker cohesion as AudiocRaver mentions above, almost every speaker with passive crossovers will benefit from phase linearization at the crossover frequency. Most speaker box types (excl. open baffles) will also benefit from a box/port phase correction in the lower bass region.
It's possible to apply a phase correction convolution with the limited taps of MiniDSP as long as you keep the correction to just the XOs. Lower bass area phase corrections are not going to be possible.
Dynamic EQ applies different LF and HF boosts to different channels (ie higher surround volume and even higher height channel volume) which in my opinion is based on an old and incomplete research. It helps lift up Audyssey's excessively rolled of HF house curve. If LF is managed independently (ie MiniDSP), its effect on the bass is inaudible so some people tend to like it. But it measures unacceptably out of order at normal listening levels if the speaker is calibrated correctly otherwise.

I feel that Room Correction EQ should be a static baseline and any additional "Dynamic EQ" or "Tone Shaping" would come later in the signal chain... Then perhaps a compressor and/or limiter...
