I'm actually wrapping up cabinet drawings for a large custom project with subs hidden below the floor of a very large, residential game & entertainment space. While this was a bit over the top using 8 units in space that's more than 110' long, the sub's design of a somewhat unique bandpass with a pair of 12" drivers allows both 2 narrow dimensions and for all output to exit at an 11.5" x 3" opening while still having quite a bit of output to 28Hz. This would be easy to screen over so long as the exit points down so it isn't exposed to direct rain. While this box became exceedingly tricky having to fit a 12.55" diameter driver *inside* a 13" wide box, loosening the width to 14" would make it a much simpler build or keep it identical to what I've already had programmed for CNC. The driver uses a rubber half-roll surround and treated cone, so should be fine as it's not exposed to sunlight in the box. Other than porous materials, UV is much harder on most parts than moisture, which is eliminated with the bandpass design and by placement under the patio cover.
I'll be more confident in how appropriate this would be for this application around the 1st week of June.
