WAF friendly dual TRIO12 sub build!

EDIT: Sub choice changed to CSS TRIO12, post #23

Hi all, so i'm going to try a new project utilizing the IXL 18.2.2 sub. The room I have to work with is beside the couch to the left against a wall. It is now occupied with an AV123 MFW 15 and I wanted more low end. So i'll be replacing it with DIY most likely. The space is 18" wide by 26" high by 36" deep....I think that would work out to 8cf not including the ports,driver,braces. would that be enough space for the sub to operate ok? Most likely face the sub toward the couch on the 36" side. What would I do with ports? (PVC)? I'm looking for a bit lower tuned response than the existing MFW15 Thanks...oh yes, I have a CSS 500watt bash amp that I'd likely use and upgrade later to a Dayton 1000watt SA1000 probably by mid spring.

That has a default subsonic filter at 30 hz, has it been modified to a lower frequency?
I haven't modified it, don't know if CSS has done it from the factory

Not possible due to the size of the driver being over 18" (the mount) and the space required around it. The best you can do is probably 20" wide in that scenario. The dimensions sound awfully close to my "easy button" build. If you cut it down a bit size wise, you should be fine.

also very similar to my 18.2 build...outside dimensions are 19x24x36...and i have calculated that to be 6.75 cuft (subtracting the port).

I am downfiring mine...once it arrives...so i will add 4" legs to raise the overall height to 29".

What if I were to mount it on the 36" side, I'll be using PVC ports if that works

CSS would only modify the HPF is you requested it. Are you able to modify it yourself? It involves soldering in 2 different resistors.
I could probably do something if I had the patience or I could bring it to my electrician on a weekend:p

It would be doable in a 18.5" wide cabinet since the driver is a hair over 18" wide. I contacted SirCron to find out the cutout diameter.

Great, would that mean a taller/deeper cabinet? Port wise would I be saving any space by going with PVC vs slot? Also what's the easiest bracing method as I am very limited when it comes to tools and woodworking skills

A slot port would be easiest. It would be 2" high and the full internal width (17") and run 32.5" along the bottom of the cabinet. There would be a 2" space between the end of the port and the back wall. This would give you a 18 hz tuning.

Green is with the Bash 500 with a HPF modified to 13.9 hz from the 1 db boost table in the amps documentation.

Yellow would be with the Dayton SA1000 amp.

Here are the drivers cutout and overall width dimensions.

Looks like this build is dead for now, the ixl is not in stock for another month and the new one shortly after that. Any other subs that would make work with this size box to achieve the same result ?
