Hey guys. I'm looking to replace my Def Tech supercube 4000 with a new DIY project.
This will be my second DIY sub, I have a sealed 15" in the opposite corner.

I have somewhat of a size restriction on the enclosure but its not too bad.
The biggest footprint the enclosure could have is 23" X 21". With NO height restriction.

I'm looking for a build that will dig down deep like my current 15".
I'm considering another 15" if you guys think I can build an enclosure within that footprint that will get low.
If not a high output 12" is always an option also.

I will most likely be powering the setup with a Crown XLS1000 amp.

Any suggestions guys? Thanks!

stereo integrity d2 driver for 4 ohms in bridged mode to your amp. 17hz tuning on the cab which at about 60 inches tall would net out to about 11-12 cubic feet. 3" x 21" slot port 36" long. MARTY SUB! performance. :-)

not sure which 15" you have or are considering, but here is the comparo between the large ported 18" with 1000 watts and a medium sealed 15" (Dayton um in this case) also with 1000 watts.

LTD, could you do something like the box you've got up there but with a 8" or 10" round port? Some sonotube that size should be easy enough to find, and something that big should keep the chuffing down. Or is the slot port just a better/easier way to go? Just curious for my own build as I'm thinking of something similar. I was looking at the Marty Sub, but it'd be longer than I'd want to put behind a screen.

sorry that I missed your post.

nothing particularly special about a slot port. it is easy to build and easy to brace.

a round port would work too. what did you have in mind?

oh yeah!

did you ever go any further with this box.  Would this perform the same as the marty sub?

I'm looking for a box 60 inches long 25 tall and 22 deep.

I thought about doing traditional round ports in my MartySub. Iirc it was going to require an 8" round port size. After buying the 8" pipe I just could not imagine how it wouldn't be too big for the cabinet as it was almost the size in diameter as a typical 12" subwoofer driver!

josh plopped a 10" port in his. it all just kind of scales the same. this was with a 21" driver.
