Custom Sub build need input for location idea...

[HaLo6]

I'm thinking of building a Dayton UM18 based sub in my living room nook. Its about 24" x24" x 24" which yields good volume, thinking a sealed enclosure. My idea is to build the box to fit inside that niche and screw it into the studs behind the drywall to minimize vibrations. To assist in that i was going to dynamat (or some other vibration dampening material) the drywall where it will come into contact with the enclosure...

Thoughts?

Is this a dumb idea?

An externally hosted image should be here but it was not working when we last tested it.

Looks like a good idea to me, although the four-legged woofer may have to find an alternative location!

You'll get lots of bass gain in the corner position, so an appropriately designed sealed enclosure would, indeed, be preferable.

yeah I doubt he'd like that corner anymore lol

now I'm thinking of cutting the bottom out of the niche and building a stand and anchoring the stand to the foundation with some rubber matting in between the concrete and the stand legs( and the sub and the base) to absorb vibrations.

Better overall to use opposed dual drivers to self cancel [preferably mounted in tandem with one wired reverse phase], then spikes or the proper durometer hardness isolation pads.

Otherwise, coupled to the foundation; I've a suspended floor/concrete block foundation and literally had the ceiling and its contents 'rain' down on us during a depth charge scene in the U-571 movie. Apparently my old stick built, clapboard sided house has a ~14 Hz Fs.
