Re: 33"W x 17"H x 14"D
If you want to use a 15 and are determined to do it, your going to need to chose a different sub. You just cant use a sub that wants to be tuned that low in a box that size. The needed port area and length wont allow it. I just ran those specs for your sub several ways and it aint happening.
You should either go with a 12 or find a 15 that has a lower Xmax and a higher Fs. Something that would need a higher tuning and a lower volume and shorter port length.
Maybe look at a FI BL 15 with the tuning a little on the high side. You might squeak that one in there? I didnt do a very accurate design, just doing a lot of rough figuring but your close to being able to net the 3 cubes minimum and have room for the port and length. Your just going to need to tune it high 39-40hz to make that work.
I would look at a 12" with a proper enclosure size and port area/ length personally. Trying to cram a 15 in there is going to be a fudge job.
