The spray stuff looks the best but is not as durable since it's much thinner. Just use a smooth foam roller and it will look just like the JTR speakers do.

If I can't think of a way to build a L/R stand, I will just get the trial Duratex and use that for my center.

Anyone have any suggestions how to build a 16 - 18 inch high speaker stand for T12's? I have 0 woodworking skills so it would have to be cuts from the people at HD. The center one I built was just a 10' 2x6 that they cut into the lengths I needed, and a 1/2" thick piece of plywood cut to the size I needed. I just put it all together.

But they don't make 2x16's lol. I was thinking about using 2 2x10's though, and stacking them, but I don't know how to connect 2 pieces of that stacked.

Any suggestions?

Being 2" too high is not going to hurt anything. My apologies if this has already been answered.

To be honest I haven't really thought about going that route too much. I kind of just figured I'd make a stand for them at some point. If I set them on my caps though, I have to put some kind of material between the caps and T12's right?

I'm about to go take measurements though to see the exact height of my listening position and see how tall of a stand I would need to get the tweeter at ear level.

EDIT:

Just took measurements. The 18" stands would be pretty ideal. My Audyssey mic is still on the boom stand and is just around 38" from the ground, and the tweeter is just about 20".

I also measured and to the right of my screen I have about 31" before I hit the wall. So I could fit the whole cap over there but would being that close to the wall be bad? I do have the electrical panel right over there as well as the FIOS box on the wall.

I can't test it out right now because my speaker wires are not long enough for my subs to be moved that farther over, so I'd have to make some new ones. Plus my wife is sleeping so I can't mess around with it right now anyways lol.

But to be honest I kind of like building things too because it's a fun project and I feel like I'm learning stuff as I go along

In regards to your stands - If you decide to build your own stands (why not!?) I'd be happy to help via PM or phone. If you decide to throw some together and don't like how they turn out, wood is CHEAP and it's easy enough to try another design. Well worth your time for the learning experience and enjoyment IMO. Check out the DIY FAQ link in my signature for a link to the boxnotes program. It's free and is super easy to use to calculate cut list dimensions for anything box related you want to build - subs, speakers, or speaker stands. And yes, the brace would go right down the middle of the box perpendicular to the top. In box notes speak you would be duplicating the "back" panel for the brace.

So today I ended up putting together 2 stands for my mains.

They are 17" x 16.5" x 14". I decided to make them 17" tall because the ideal listening height at 18" is for when my seats are all the way up, and I tend to watch movies with my chair reclined a bit, so I figured hey why not drop it 1 inch

Anyways here are a few pics I snapped.







I'm going to order a gallon of Duratex right now and finish the 3 stands with it. Tomorrow I'm going to fill in some gaps and sand it all down, getting it ready to be finished with the Duratex.

I'll post some pics when it's all said and done.

Heading to Guitar Center to get a mic stand that will hold the Audyssey mic correctly and will pick up a SLP meter too. Since those of us with JTR speakers have to tweak the post Audyssey settings what do you do first, run Audyssey and then adjust level calibration or level calibrate first then run Audyssey? Every time I run Audyssey it puts my LCR at -12 and the subs at -8db. Basically it tames the hell out of my system volume wise. Do I need to consider attenuators?

One last question. What do you guys set the crossover at for your JTR's? Audyssey loves 80hz but I figured it would be best to ask here.

Still puts LCR and subs at -12. Pulled out the SPL meter and the LCR's are at 75db (at -12) rears are 71db (at -2) and sub is at 55db. Shouldn't all of the speakers be at 75db during level calibration?
