Hello fellow DIY'ers. After ~1.5yrs in my first house I've managed to complete most of the projects that have had priority over my home theater/man room. I've been slowly working through drywall and other updates, and now I'd like to start on an in-wall subwoofer enclosure (to allow placement directly between mains, to reduce "stuff" on the floor and also since I'll be upgrading to a LCD/plasma eliminating magnet effects). It's a Cape-style house, therefore allowing substantial depth on the long ends where I can flush-mount the box. I'm creating this thread more for people to point out any glaring errors than looking for a hand-hold along the way. Hopefully I'm doing ok here .
Room Details:
Length - 31.5ft
Width - 16ft
Height (max) - 7ft
Area - 504ft^2
Volume - 1634ft^3
Subwoofer Hardware:
Driver - 15" Adire Tumult Mk1
Passives - 2 x 18" Stryke/AE 2500g
Amp - Kiega 1000W plate
EQ - Behringer BFD
Previously I built a ~4.5ft^3 (120L) gross enclosure for the sub/PRs, I loved it. Now that I have more room, and due to the in-wall design limiting me a line-array arrangement, I've modeled up a ~7ft^3 (200L) gross enclosure which results in a lower ~16Hz tune. This gives me room behind the Tumult to allow the motor to cool and gives me enough meat around the driver/PRs to create a 1.5in thick wall, if needed. Although I may end up running only 3/4" ply and incorporating an additional brace width-wise if others consider that sufficient. The entire box will be lag bolted to a 2-by frame behind the wall attached to the floor and roof joists. A trim piece will overhang the drywall cut eliminating my need to tape/mud and allow for easier patching should I decide to take the box out. Plus it'll flush-mount the drivers.
1) I can't think of any - but any negatives expected with my intended subwoofer location?
2) Other than slightly running out of PR excursion in the low-teens, any concern with the increased box size?
3) Yahoo - I can't wait to finally get this started!
Thanks in advance - Nat Ward
