I found that I needed at least 2 full inches of space underneath my single fan for much greater efficiency of air volume movement. Also, the extra height stops turbulence noise generated from a sudden 90 degree change of air-flow direction. I'm trying to come up with my own solution involving a special amplifier table top with a filter box underneath the entry to the fan to stop recirculation of household dust and also to bring the noise level down even further.

the fans are about 20mm thick, 100mm types...
made of clear plexiglas, top portion is 6mm thick,
front, back and sides are 9mm thick,12 x 17 x 1,75 inchea height...
the fans are 12v 015A types connected in series paralllel
powered by an ibm laptop psu, rated 24 volts at 3 amps...
oh, i made 4 blocks of plexiglass 3/8 x 1 1/2 squared for the 4 corners of the cooler, that is where air enters
Some progress
2 pcs .250" thick 6061 T6 material for 2 monoblocks

Very solid. By the way, how did you manage to get the photos up in super large size?
I put them in an album on an Ipad pro taken with the same camera. And hit "invite all"
I never could figure out the attached thumbnails as I could not manage the pics for whatever reason
I could only post 1 pic at a time
Just straight resolution and no downsizing on the Ipad

yes, first i quoted your posts and replied to each, so then having three posts in succession, i decided to merge all to make just one post....begging for your forgiveness...
Finally my version of the Tim Mellow amp is running on a dummyload.
After some assembly errors 🙁 the amp works fine.
The transformer cover needs some paint but it is too cold outside. I am still searching for an output protection, because I am using the delicate AER-driver (full range).
