that's as far as I got so far. more bracing to come. I can subtract the driver and port volume and 1cubic ft of bracing that maybe close to 650L. is bigger than that bad?. 26.5 h 29.D 54.5w.

Woah that is a box. But I would not put a TV on it. I built a sub that fits into my entertainment cabinet (measly ported 12" driver) and even at less then half volume it causes sympathetic vibration in the TV cabinet. I am in the process of trying to isolate/dampen the cabinet now.

The setup is in a good location. A shelf just above the sub should work.

Not at all. There are bigger builds then yours in the Database.

holly smokes! you guys. I never thought about the poor TV. if the vibretions killed my wifes big old tv I might have to get a front projector. hey mike, what would the shelf sit on? maybe I could put a matress between the box top and the tv. its very big and heavy. it will take a forklift to get it up there. I think I'l look inside that monster and see if I can take some stuff out. like the speakers. ect. I'll wait till the wife leaves.

Post the make and model of your TV so we know what we're dealing with.

it,s a toshiba 53ax61.

Well that changes things a bit! I was not expecting it to weigh 240 pounds! I'm not sure what to suggest here. Hopefully someone will join in with an idea on how to isolate the TV from the subwoofer.

How bout building a heavy duty shelf above the sub. You have 3 sides so it should be pretty easy to support the shelf. Use 2x4s on edge, sort of like a sub floor. Attach a sheet of plywood on top.Cover the front of the 2x4 with a nice piece of 1x6 ripped down to 5 inches or so, for aesthetics. You can try putting 2 auralex subdudes on the shelf under the TV. That might help a little.
