tktran303 Posted July 16, 2020 Share Posted July 16, 2020 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. Quote Link to comment Share on other sites More sharing options...
Ricci Posted July 20, 2020 Share Posted July 20, 2020 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. Quote Link to comment Share on other sites More sharing options...
tktran303 Posted August 7, 2020 Author Share Posted August 7, 2020 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. Quote Link to comment Share on other sites More sharing options...
Ricci Posted August 19, 2020 Share Posted August 19, 2020 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. Quote Link to comment Share on other sites More sharing options...
tktran303 Posted November 25, 2022 Author Share Posted November 25, 2022 A much belated "Thank you for your response" I ended up building a different dual opposed this year and can verify that the there is no need for thick baffles; as the vibration is VASTLY reduced this way. Hope things are going ok for you. Quote Link to comment Share on other sites More sharing options...

JSS One of those wild ideas during COVID19 when we were all locked up inside. In all seriousness, I ended up buying an off-the-rack TV cabinet. The TC Sounds LMS-R 15" each sit in a sealed 2cu foot cabinet. Dual opposed bigger vented subwoofers, a dream project for another decade, I think...
