Ok. Got everything put together and tested. Got a wireless sub adapter that works, but was a pain to get working. Had to turn up the sub output up all the way on the receiver to get it to actually output sound to the sub.
Anyway, here are the sub box and amp pics. Will begin construction of the actual table in the next few days.
I used one of my unfinished boxes from the now deconstructed theater. It's one of the first I ever built so it's ugliness can be hidden inside the end table.
Amp works great. Used an old receiver that's for my garage speakers to make sure everything does what it's supposed to. Forgot how nice it is to have real bass. Even from a cheap 12" driver and only 300w to power it. Very nice. Sounded good in the living room where it's home will be.
I'll update with build pics of the actual table, but I'm going to put my plan on here in case anyone can find a better way to do it.
The actual table will be 27"H 22.5"W 17.5"D so the 15x15x15 box will fit inside just fine. Snug even. I had planned to build the table and cut out the driver diameter in the bottom since this will be a down firing sub. Then I just have to cut out the back for the amp. Once I drop the sub box into the table I can either screw it in place or glue it. Or both depending on whether or not I ever want to be able to remove the box. The main thing is that I don't want the table to rattle at all. That is the most important thing.
So, good plan or no?
