I'm looking to build a sub that will fill in the low end for two pairs of Emotiva UOM-6.2 outdoor speakers.
The plan so far is to recess the sub in the ceiling of the covered porch. The porch roof is ~8 feet deep, so the subs will be protected from direct weather exposure, although humidity is still a problem. I chose the Bravox 12" because of the poly cone and aluminum basket. I modeled a few different drivers and these perform well given the design conditions. It also helps that they're on sale
The distance between ceiling joists is 14-3/8", so the enclosure was built to those dimensions. The distance between joists limits the diameter of the driver.
Proposing to drive them with NU1000's, giving 500w per driver. The drivers are slightly above excursion at 500w.. I doubt I will actually get 500w out of the NU1000, nor is there any desire to be playing these at max levels, so I don't anticipate any issues.
The enclosure ends up about 3.4 cu.ft. no plans the HPF them.
I'm new at this, so if anybody has any suggestions, please share them. As far as mounting the enclosure-- would there be benefit to locating it close to the wall-ceiling intersection? Or does it not matter outside?
