Interesting set up.

What's your opinion on the tube traps, I've always wanted to try them out but they're so expensive.

The windmere fan and magneplanar bass panels are something I've never heard either. Pretty cool in theory.

I am surprised you didn't orient your room longwise to get better room acoustics, but I'm sure it sounds great.

I have been an audiophile for 50 years and ASC tube traps are the most versatile
acoustical devices available. Half the surface area of the traps have a reflective
membrane that can be rotated and directed to provide awesome imaging. Without
this reflective surface the traps would make the room way too dead and ambience
would be lost. One needs a lot of bass trapping for a real improvement in bass
quality. I use 21 large bass traps and 15 smaller mid range traps and this gives a
real improvement. No early reflections, bass that is powerful and has great impact.
The mid range traps are 3' apart around the entire perimeter of the room and this makes
voice reproduction very articulate and one feels like there in the same hall (space) that
the recording was made in. They are expensive but are worth the cost. I know I
go against what most say about using the long wall for the front speakers, but I found
that this gives a much larger sound-stage and the ability to position the speakers
further away from all surfaces. The Martin Logan Summits are 6' out from the front
wall and the Magneplanar bass panels are almost 10' from the front wall. This greater
distance reduces comb effects greatly and the depth one gets is awesome. Side wall
reflections are negligible because of the even larger distance from the walls.

I have also, in the past, built diy acoustical devices that worked well, but were difficult
to build and the desired results were no where near as good as the ASC tube traps.
This is the room I had many years ago with the acoustical devices I built. They are
poly cylindrical diffusers, slat resonator, and mid range box resonators.

The Magneplanar bass panels provide some of the best mid to low bass that I have
heard. With 1254 sq. in of surface area and very low mass, they provide well
controlled and realistic bass reproduction. The panels are bolted together and to
the floor, and the bass is both powerful and has superb impact. Also the low frequency ambience one gets is awesome!!! Together with the rotary subwoofer the bass extends
down to below 1 hz!!!
