It's hard to believe it's been nearly 10 years since my last build! I built out our unfinished upstairs/attic and have been using a pair of T39's (from my signature) as makeshift home theater subs. They sound great, but they're obviously not designed for HT use and drop off below 35hz pretty quickly. When I framed the area behind my TV, I specifically made enough room for two THTLP's to go there and the time has come to build said THTLP's. Once these are built, the T39's (cabs only) will probably be up for sale if anyone is interested (SE Ohio).
I'm going with 23.5" wide panels to maximize plywood use (1/2" Arauco) and am hoping to build both cabs with 5 sheets assuming I don't make any really dumb mistakes. So odds are I'll be purchasing a 6th sheet
I'm reusing the Lab 12's from the T39's. I'm going with the "extended surround drivers" option in the plans to potentially use 15's in the future so I'd only need to build a new mounting panel instead of a whole new cab, but I'm fairly confident the 12's will be plenty.
So first the space in question. The subs will go behind the TV and you can barely see the edge of a T39. For reference, the TV is 85".
Getting started on first cab:
Using my MPCNC for the 2/6 braces. You can see failed attempt #1 in the top of the frame:
Making some good progress:
CNC to cut out router templates for the curved mouth braces:
That's all the progress for now. I'm hoping to get them finished within the next few weeks. They'll be finished in Duratex.
