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...

How does it measure? Doesn't sound like 16Hz... sounds like distortion

Do you have any measurements ?

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.

Add first and then subtract later. Or subtract first then add later. It’s all the same in terms of maths. for a commercial product that you were trying to sell you probably do want to show that it has good bass response and works well in many rooms so you’ll probably need to boost 1st to target your Anechoic response (-3dB/-6dB/-10dB) etc. and allow user to EQ for good in-room smooth bass response. For your own use no need to worry about that. Just plonk it in for desired room; take measurements at the listening position and EQ it to your taste. if you are using it in theatre with multiple listeners, use of multiple sub place throughout the room may help smooth out the bass response.

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 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.

Are they NLA?

There was a sale on this unit last week. US$370!

Canada. i currently in Australia. closer, but no cigar...

This unit is currently on sale at Madisound.

Whereabouts r u Ricci? anywhere driving distance to Vancouver? Even if we meet halfway...

Well your SAN 214.50 measures great, and looks like unbeatable value. Makes me look into their catalogue to see what their other drivers are like. There is a SAN215.30 with a bigger voice coil, and this tweeter is probably also amazing value: http://www.lavocespeakers.com/single-product/?id=169 Is this a Chinese company with an Italian name? Or an Italian design house with manufacturing in China? what is “100% Made In Italy Electroacoustic Excellence”?
