TC LMS-4000 15" box help

450 seems kinda cheap for a tc sounds lms woofer. yeah it doesn't even have the original coil, which probably took away a lot of the price.

Yeah, the LMS coil is the whole point of getting an LMS sub. Honestly, it's not even a LMS anymore, just a normal sub with a normal coil. The LMS tech in the coil is what keeps the BL so linear and allows ~3" of clean excursion.

alright awesome, ill make a simple box for now until i can get some actual specs on it. i feel like 4 cu ft net tuned to 31hz will be okay. unless someone recommends otherwise?

Don't know why you're shooting for such a huge box, this isn't an HDC3. I'd go for 3.5ft^2, whatever frequency you want, and lots of port area since I'm guessing you want high output.

3.5 cubes is about the best for a tc 15 I've owned about every tc 15 made and 3.5 tuned at 30hz is where they like ...

You could honestly get away with 3 cubes, that motor has a lot of force. TC sounds subs have always been small boxed monsters.

Even without an LMS coil, the sub should perform quite well, if it's build properly.

I'd personally run 3.5cubes tuned to 32 with 60^2 of port.

Gross volume is meaningless figure for spec use, a brand new LMS-R 15" sub is $433.
