I put two 8 mm MDF boards in front of the drivers:

The boards are really meant as ceiling.

Marked the cut-outs:

J-Bolts might help too. You can use them to hook the basket and pull it towards the wooden frame. Your aproach does look more elegant than H-Frames.

Attached the baffle loosely:

Arranged the side baffles to the wall and baffles straight back at the inside.

Had to do some adjustment before finalizing the baffles. The end result looks more or less the same as above.

Used more of the vibration dampeners in order to decouple the baffles from the floor:

Almost done now. Put some heat pipe isolation cut in half to close the gap between the ribbon and the OB baffle:

Measured with XTZ Room Analyzer and HolmImpulse.
It was quite tricky, those large baffles really baffled me.

Adjusted Allocator accordingly.

Listening...

Big grin

Great idea!
I bear that in mind if the current solution proves to be inadequate.
Or perhaps I´ll apply them anyway, just to be on the safe side.
On the other hand, they will constitute more "air resistance" for the backward wave.

Currently I only have the centre baffle attached, not the side wings that is (see picture in #23), to get a greater openness for the backward airflows.
One rule of thumb states 10 x Vas of free space behind the baffle, so that would be 15 cubic meters per side. I have only got 10 cubic meters in total, so it got a little bit stuffy.

The grin got bigger with this change of set-up.
