I have a nice SATA sprayer that I was planning to use for them, but I just brushed them and was done. I won't be so lazy on my mains since they will be out in the open.

I will play with the delays and phasing a bit and see if I can figure something out and report back. There is so much happening right now with the remodel that it is overwhelming.

I hear you there! You must be one of those guys who is always thinking ahead to the next project too... ;)

Somebody in another thread mentioned that I can time align these instead of moving them, ie, put them in the corners where they will look the best and benefit most from corner loading. Then change the delay on them until I find the smoothest response, which is supposed to be the same as moving them. Can this work?
While that might help with the timing, my guess is moving is better. Your biggest problem is likely room modes, rather than timing. That being said, some acoustic treatments combined with an EQ that includes time delay could probably do the trick.

It's OK Mike, that's why we have this support group: to talk about our urges. I am already thinking about a LLT like yours for behind my couch for nearfield. I have 12g wire running there and to the two rear corners in case that doesn't do it. I am almost ready to start my SEOS mains, so we will soon be twinzies with our giant subs and SEOS. It's killing me to have these subs finished and looming overhead while I work on the remodel. The sad thing is that I have a single SDX15 in the temporary TV room, and it sounds so good in that little room. Big rooms really take the oompf out of bass.

lol, I know how you feel. I have a 12x22 foot front room with my HT gear, but it's a southwest ranch style home so it has open archways to a nother 8x22 foot room, a kitchen and the back hallway... I'm seriously considering doing a GJallahorn or two or adding another 2 marty subs. to make 4 of them

sooooooooooooooooo, how are you liking the horns doug?

I'm still thinking of building a pair with the UXL instead of the LMS ultra (price is too big for too small a performance gain in my situation) to replace my two 12 cu foot ported SI 18's.... they give you all the output you could want? my two marty subs are getting tapped out in my ranch style house and it's either 2 of these, 4 more SI 18's and make my two into 6 sealed, or just add one or two more marty's.... (yes I know, the disease to build has set in again)

To really firm up the box I'd put granite tile on the exterior. Would add a lot of rigidity and mass. Though you'll need a fork lift to move it around...hey, you've gone this far why stop now!

Don't need more rigidity or mass on the sides. Most of the pressure is inside the throat near the driver. The weight and size is already pushing it as well.

There are not many other drivers if any at all that will work in this horn other than the TC Ultra.

Looking at a TC-9 in 12" and 15". Didn't like the Qts on Ultimax 18".
Those drivers dont work in the Ghorn though. If you would like to start your own thread on using those drivers in a build please do. The Ghorn is no longer because the driver is not available anymore. If you would like to build a large horn with extension similar to the Ghorn then build the FLH Submaximus.

The uxl-18 made a good drop-in for those who can't find the ultra

The UXL prove to work "OK," in the Ghorn. That is also why LTD decided to make a new horn design for the UXL.(Submaximus) When inductance simulated along with the horn design things dont look as pretty anymore. So that is also why the large driver VC attribute is now a part of the Horn Reponse simulator.

true, I forgot about the submaximus... although the UXL-18 does whicked in the Lowarhorn, which is kind of an offshoot of the Ghorn with similar results and want to keep the horn style of subs

Yes that is another great option. Not as well documented but another great example.
