Just got back.
I like the closed back sound.
Fuller.
Fatter.
Richer.
The cabinet looks much better with the filler panel in it too.
(Probably made a noticeable change to it's sound as well.)
Nice work Ray.
If you take your 4" hole saw to the backboard and go get one of these at the nearest
Lowe's you can have a quick change fully closed/ partially open back on the cabinet.
Just make sure you have enough space for the plug between the backboard and the speaker magnet.
Thats quite a mousetrap you've built yourself, enjoy.
I just finished my DIY A/B/Y and have only tried it to switch between channels on the 5e3 Deluxe and on the 18w TMB, but have not run 2 amps together yet.
It looks like crap but works great.
