LOL! You remind me of that old Super Glue commercial where the construction guy was hanging from a beam by his hard hat!

I used a ton too, especially when laying the final side down. I wanted to make sure that just in case I missed with some screws, that the PL would help me out.

Same here. My buddy helping me was like WTF when I was caking it on for the last panel. I wasn't about to tear it apart because of an air leak.

That's exactly what my line of thinking was, I only want to build this thing once.

PL is strong stuff. That's why I didn't try to take out the OSB I used. I would've ripped the panels up pretty good, so I left it in.

What did you use OSB for?

Oh man, it was ugly! I didn't know that the plans called for separate pieces of wood for panels 5 and 6 and I wanted solid pieces for them. I was going to go buy another 4 x 8 piece of ply when I remembered that I had a bit of OSB left over. So my panels #5 and #6 are made out of OSB. I braced them as good as I could (because Bill says that they will crumble over time) but we'll see how well that goes.

HAHA im not laughing at you exactly. Just this idea, imagine showing this thing off to a friend your both looking in the mouth of it and then next thing you know you hear a huge hiccup and it starts spitting wood chips at you. That would be hilariously devastating if you know what i mean. But theres no need to worry about that because it will never happen,stuff like that only happens to me.

Well we are going to load in the woofer tomorrow night and finish up the access panel. One issue that we realized just yesterday is that I can't get this thing into my Subaru forester, it is just TOO BIG! So I have a buddy with a Suburban bringing it here late tomorrow night. So I think I may actually get to play with it Tuesday and see what this big guy can do!

You got a car amp and a pre-outs in your buddy's Suburban? Have some fun with it on the way to your house

I know, I know. Before I get bashed by the perfectionists. It's not a car sub, just playin' around.

I'm well aware of the auto tuba, but just was wondering why you couldn't use the THT if you had a big vehicle?

Doing two fake doors on the front to cover the access panel (doors will be removable) with a fake drawer above the doors. Wanting to do a granite top. But the absolute finishing may have to wait till closer to spring with warmer weather for doing painting and such outside.

Im with you on the weather but today was beautiful and i believe tomorrow is suppose to be as well. Just shut the garage door and inhale the fumes the weather wont effect ya . How will you secure the doors to where they dont rattle from the vibrations and still be removable? I like your idea and might have to steal it haha. Once you get it to your house and in place post some pics. I like seeing how people have integrated such a large box into theyre rooms.

Well the first priority is to have the woofer loaded tonight and the access panel set, and then make sure that I have NO AIR LEAKS! I have the in laws coming into town on Thursday and really want to do any EQ/GAIN/CROSSOVER tweaking that needs to be done and also run Audyssey with days to spare to make sure that I got everything perfect before they come. My father in law is a bit of an audio guy and I really think that he will be able to appreciate that Tuba HT and what I have done with the room. I sold my reef aquarium just yesterday afternoon, and now I am able to set my mains (Klipsch KLF-30's) about 3 feet further apart to give me a wider sound field. So the aquarium removal along with the Klipsch SUB-12 removal and the Tuba HT addition, things will be sounding quite different this week! I can't wait!!!!

As far as the fake door attachment- I was thinking neodymium magnets. They come in very high strengths (even dangerously high strengths in very small sizes) so I thought they would be quite easy to use, though I am not sold on the idea quite yet. Definitely open for suggestions.

Im think i may try to comeup with something fancy for mine. But not sure yet. Does your access panel have to be on the side facing into the room? When i invisioned the door idea i pictured regular hinged doors of a cainet meeting in the middle fully functioning. But having something that held them forcefully in place in the middle. Im sure if you buy some super strength magnets it would work. But cant say for sure because im not sure how much vibrations you get on the exterior of the cab if any. But just to be safe you might want to line the edges of each door with a very thin maybe felt like material. Just like the round dots you can buy from the store for door jams and cabinet doors. That should take care of any wood on wood rattling. Who knows its just an initial idea could be superb or could be rubbish lol. Almost forgot i was also thinking if it could done without sacrificing performance even putting on some nice legs. Maybe put some of the 4" rounded furnitire legs you can buy premade with hardware included at lowes. They are flat on both the bottom and top so would provide good support. Dont know if it being off the ground would change anything performance wise. I doubt it would but then again you never know.

What version of Audyssey? What else will be in your audio chain from receiver to sub? This is VERY IMPORTANT. Audyssey can inadvertently give a 9dB boost to subsonic frequencies.

You should be good with Neo magnets, just put a small layer of felt on the deorative panels where they will touch the THT so the decorative panels won't rattle.

DO NOT LET ANYONE PUT LITTLE NEO MAGNETS IN THEIR MOUTHS!! There was a kid near where I live that needed parts of his intestines removed because he swalowed two of them at separate times, and they somehow got stuck together inside him later, while each of them was in a different part of his intestine....not good.

I plan on putting spike feet on the THT. Will glue 4 wood blocks to the bottom four corners that are just high enough to put the metal threaded inserts into that come in a spike feet kit. Anyone know where I can get spike feet that are around 4-6 inches long?

I have the Denon AVR-989 which has the Audyssey MultiEQ XT Dynamic EQ.

I have essentially the same receiver, 2809ci. What amp will you use for the THT, and will there be anything connected between that amp and your receiver?

[EDIT: I remember you have the Dayton standalone amp. I would setup using Audyssey with the subsonic filter OFF, and then run distortion tests or play some real LFE material at the levels you will listen at, and if it sounds funny, switch the subsonic filter on. Then play with the parametric EQ to get the most distortion free sound.]

Audyssey does a damned good job of setting up EQ for you. You should just have to adjust the crossover settings (if that). Use all 8 positions when you do the setup, like it says in the Audyssey setup guide (also here on the AVS forum).

Thanks for the heads up, nothing will be between the Denon 989 and the Dayton SA1000. One thing I noticed is that the Audyssey really messed up the crossover settings for my surround speakers, but I think I read that it was an issue with the Audyssey calibration and that it is common. So I think I will set the THT at 80 hertz and below, then go ahead and run tests to see at what point to set the subsonic to.

With the output of the THT any conceivable benefit will be so infinitesimal it's not worth the bother. For that matter IMO a sub that measurably benefits from spikes isn't much of a sub.

Gotcha, I guess I will just put some modest feet on the THT and be done with it then. Thanks for the input Bill!

I wouldn't even do that in a carpeted room. Feet will make it impossible to slide about and will put permanent dents in the carpet.
