I would just use a grille material and have a picture printed on. Then it would just look like two paintings or pictures being hung. Similar to GIK Art panels.
I like the idea of printed grille material too. Or what about making them look like HVAC intakes or something? It might add to the stealth factor. Will you keep the wood paneling on the walls after the remodel?

Interesting. The LMS-U's are not doing it for you? My HT is a little smaller than yours (~2300ft³) and I have been looking at doing two (maybe 4) of the SI 15" subs in 3ft³ sealed boxes. Do you have more than one room attached to the living room?

Of course!

The walls will be Sheetrock, so the hvac idea would work too. They make a a wood grid for old house floor returns. I could paint that wall color and it would blend in nicely.

There are some big openings in the room so it has trouble pressurizing. Two ported lmsu would be enough if I placed them in the corners.

Yeah, I was thinking something along those lines could work well up there without looking too out of place.

Re: Doug's dual GJALLARHORN build

A little progress this week. I climbed around in the attic for some prep work and found that there is a load bearing beam right in the middle of one vent, and a bundle of wire in the middle of the other. I am back to putting one in each of the corners on the left side of the room, vented through the vaulted ceiling. It also models fairly flat with Room Sim in REW, with not much of a loss in db. The front left corner modeled best, back corner worst. The two together work nicely to compliment each other for the room modes. It should work nearly as well, but not as nice as they would on the front wall.

I picked up the Kreg Jig, screws, and 90 degree attachment for the drill today. Not too long before I start making sawdust!

Love my Kreg jig. Made things so much easier.

Looks like this will be an awesome build. If you want to conceal the grilles, do a google search for "diy movie poster acoustic panels" and you'll get a link to a great reference thread with the James Bond posters. You can have them printed to look like anything at all.

My neighbors are deaf, so why not?
Just an amusing side note on this. My mother in law, who is deaf, was visiting one day when a friend and I were watching Die Hard. I guess we had it turned up a little loud, because she came into the room with the "WHAT ARE YOU TWO IDIOTS DOING!?" look on her face. While she couldn't exactly hear it, deaf people are pretty sensitive to other subtle senses, and she DEFINITELY felt it, and knew we were up to no good.

Re: Doug's dual GJALLARHORN build

Funny! I have decided to paint the inside white and go with no grills at first, and then see what happens. The printed panel idea was the top of our list before they moved back to being ceiling mounted through the attic. I'm surprised we don't see more people using that for speaker concealment and sound treatment panel covers.

I have only to paint my bathroom today and install a countertop and I should finally be able to get these things started in the next week or 2.

Re: Doug's dual GJALLARHORN build

I'm finally ready.

I spent the last few hours going through the 37 pages of plans for the G-horn, learning the process, and converting each measurement to fractions from their decimal form. I have 9 pieces of 18mm Baltic Birch and 4 pieces of 12mm to order tomorrow for Thursday pick-up.

Already planning the new mains, front highs, and surrounds... I have a sickness!

So I take it you are using 5x5 sheets?
