imral3's system progression - aka - new house, new listening room

[tomlinmgt]

Today 1/17/23 (green) vs 12/16/22 (red):

Much flatter. Changes made included sub HP xover of 30BW12; repositioning of chair and speakers; panels put on 45° angle of front corners & raised 8" above floor.

I wonder if straddling the corners with the panels or changing the listening position cleaned up the 150-1500Hz region? What are the panels using for absorption media and what are their dimensions?

Yes, both angling panels into corners AND moving chair+speakers contributed but, REW measurements indicate panel placement had only minimal affect. It was mostly chair+speaker position.
Panel dimensions are approx 37½"H x 25½"W x 3"D stacked two deep. Not sure of the technical properties of the foam other than "cheap" and probably not ideal for audio use. It's what I have so, I gave it a try.

@tomlinmgt The panels are 100% polyester fiber padding.

New speaker position, new measurement:

Today 3/16/23 (green) vs 1/17/23 (red).
Trace doesn't look as good but, new speaker position has created a wider, deeper, and more holographic sound stage. Let me just say, "what speakers"? They've just vanished.

I isolated just the right speaker and moved it around, taking measurements with both tape measure and REW, to see where it presents its best in my room. Once determined (after oh so many REW sweeps) I simply mirrored those physical measurements with the left speaker. The above is the measured response, with the subs also.

The left speaker didn't measure as well, by itself, in the new position. After I listen to this current setup (because it does sound shockingly good) I will probably isolate the left speaker to see where it presents its best. Maybe then there will be a surprising compromise of measured performance with left and right speaker position.
My fingers will be crossed.
Thanks for following along.

Enjoy the musics!!

Hey folks! Kinda lost my way. Haven't had much desire to listen to music lately. When I "force" myself to listen I can enjoy one album, then I'm done. Today I decided to fiddle around with seat placement (drastic 4" move!) and sub settings in miniDSP control panel. Today 10/1 (blue) vs 7/10 (green):

 

[imral3]

More fiddling, more bass, more better?
Red=Right spkr
yeLLow=Left spkr
Blue=Both spots
Green=spkrs+subs

I'll give this a listen for a bit but will probably tame the bass just a bit. Maybe.

Enjoy the musics!!

Today 10/25 (green) vs 10/16 (orange?):


No change other than upgrading TV from 42" to 65". Silly me, I don't even want the TV in the music room... so what do I do? Put a bigger one in, of course. Small house (900+ sq.ft.) and it's my current option.

What's the RT60 (REW) look like?

 

[imral3]

Not really sure how to interpret the RT60 but I do understand the RT60 decay somewhat and know the bass is way muddy.
I welcome your input.

Swapped out the two (2) Aiyima A07's for two (2) Fosi Audio V3 Mono's. These new amps sound amazing!
Have a small fan (off camera to the left) blowing across the amps to help keep 'em cool... They get pretty warm when pushed!

The green trace is today. New recliner, new speaker positions, a couple more cheap panels, minor minidsp tweaking for the subs. I am diggin' on the sound big time!

Happy listening my long lost friends.
