Dual opposed TC sounds subwoofer/TV stand

Recommended Posts

I have a pair of TC Sounds LMS-R 15" which I purchased new back in 2013 but unfortunately never got around to incorporating into a system.

My needs have changed- I recently moved house and need a TV cabinet- and I thought I might be able to kill 2 birds with one stone-

a dual opposed subwoofer that serves as a TV cabinet.

These fancy fandangled flat screens are getting quite big. Mine is "only" 55".

I'm thinking 12cu ft tuned at 21Hz for an F3 of 19Hz gives a maximally flat response, using circular or rectangular ports.

This would be an interesting design. If you can try to use at least a 6" port for each driver. (180cm2 area). Dual opposing the driver will keep cabinet vibration down from the reciprocating driver mass.

Thanks for your reply.

 Here's my design- each LMS-R 15" gets 7.5 cu feet dual 4" ports (150cm2 area) , each about 18" long for Fb of 20Hz.

F3 is about 18Hz and F10 15Hz.

I should probably make the baffles double or triple thickness.

I wouldn't bother with triple thick baffles. Most of the vibration reduction would be from coupling the drivers through the cabinet walls in the opposed arrangement. Double thick baffle is good for counter sinking, but not really needed for strength in most cases.
