Re: Dubwoofer's Tuba HT build
Haha I think I have a picture of similar. We just grabbed everything in the garage and piled it on top. You have to be sure it's being compressed. 
4xOT12s, 2xT39s@22", TTLS@18", 2xT60@18"
Re: Dubwoofer's Tuba HT build
All done. I put about a hundred brad nails in each side to reinforce things.

Uhhh...
Alrighty... It engulfed my garage in a 30Hz tone that shook the doors, walls and lights all while sitting on the saw horses in the center of the floor. That's just ridiculous.

Re: Dubwoofer's Tuba HT build
This has got to be the cleanest THT build I've seen here, it's just beautiful. 
From the description it sounds like you don't have any leaks, but I'd still check around the driver to make sure. Aquarium air hose makes a great "stethoscope" to listen for leaks, play a 20hz tone and the tone will be inaudible but you will be able to hear the air rushing out of the leak.
Are you going to finish it? I'd go as far to say it probably wouldn't need much finishing to be WAF approved, it just looks that good. Great work!

If it sounds as good as it looks then you're all good.

Re: Dubwoofer's Tuba HT build
Looks very nice, congrats. Curious though - that's the first time I've seen a plate amp mounted into the chamber cover - is there any concern that the backwave could stress the plate amp? I guess it could be boxed in if that was truly an issue, but then it would reduce the volume of the chamber?

Re: Dubwoofer's Tuba HT build
It wasn't at first.. The only leak was from a small gap in the amp's gasket which I filled with a dab of sealant. After that I could not detect any leaks in the box or around the driverDrey Chennells wrote:Unlikely the plate amp is airtight..fitzwaddle wrote:Looks very nice, congrats.

Re: Dubwoofer's Tuba HT build
After moving it into the home theater... It's good I'm a bachelor.
So far no problems at all with the amp mounted on the access cover.
I'll need to do something about the rattling movie posters and lights

Re: Dubwoofer's Tuba HT build
That's good Dub but be sure to carefully check the rca jacks and highlevel speaker inputs, etc. as they are usually leaky. That chamber has to be 100%.Dubwoofer wrote:It wasn't at first..

Re: Dubwoofer's Tuba HT build
Yep, everything on the amp was sealed with GOBS of goo and and I can't find any leaks using the stethoscope tube method.That's good Dub but be sure to carefully check the rca jacks and highlevel speaker inputs, etc. as they are usually leaky. That chamber has to be 100%.
