I had actually planned to run subs down each side of the room. However this was before the new Trinnov announcement. They are due to release an update most likely early 2024. This will reduce decay times down to sub 1ms for bass which would be a game changer.

It would also level the bass within 1-2dB for every seat in the room. This Is a massive gain in performance.

For this to work you need subs on lower and upper levels and they must face each other. This system isn't designed to have side subs.
