I am getting ready to start building two THT subs and need to decide what size to go with. I have looked at the comparison charts that come with the plans but don't really know what those lines mean in real life performance. I could find the room for the full 36" wide version but my placement options would be a little more limited not to mention it wouldn't even go through a doorway if I ever needed it to.

So, is the extra size worth the trouble or is the difference negligible? Can I build it to any width or is it best to stick with either 24" or 36"?

Bill can anwer best, but you can build any size in between 24 and 36".


I believe you get slightly more output and better extension as the size increases.

Rob beat me to it.

A little deeper extension and maybe a little extra sensitivity.

I was just kidding about the innuendos that could easily be derived from the replies

I believe the general wisdom here is to build them as wide as you can manage. With a wider THT comes a slightly flatter response down low, as well as slightly higher sensitivity for said low frequencies.


If you want to build it wide, but just narrow enough as to allow removal of the THT's via your room's doorways in the future, I'd say that would be a wise decision. There have been a number of builds with that consideration in mind followed through with great success.


My official advice, build it as wide as you possibly can/feel comfortable with. The wider the THT, the better the frequency response.

Getting it in and out of the room its going in is no problem I was more concerned about getting it into a different house if I were to move some day. Just wondering if the return on the extra 12" width is worth the potential trouble.

Theyre all correct. As long as your building your THT's using the dayton 15" driver it can be anywidth from the minimum which i believe is 18" up to the max which is 36". So whatever the max width is you feel confortable with cut all your panels 1" smaller to account for the 2 1/2" thick sides that will cap those panels. Build as wide as possible is always the advice. But the 24.5" versions seem to be the most common since its about the smallest you can go without sacrificing too much performnace.

hi guys,


would there be big significance in performance between the 2?


a 12" sub driver in an 18" wide THT vs 15" sub driver in an 18" wide THT?


i already have a 12" JLw3v2 sub which BFM says is good for a THT while i will start from scratch if i go with the 15
