I'm not getting email notifications for my thread anymore so I missed the well wishes! Merry Christmas and a happy New Year to you as well. We were certainly greatly blessed last year!

All of my speakers are now here, with the exception of subs of course. I ordered my Speakon connectors and Duratex. I'm looking forward to getting some time to put my speakers together.

I also finalized my layout changes and sent that back to Nyal for review. Once he's done with that he'll get my acoustic plan finished up. I'm hoping by then I'll be done with school and I can take a little time to finish up the room. At least finish as much as the budget will allow. I'm planning to pull my columns out, fill in the wainscoting where the columns were, cut down my columns by 8", and then put them over my speakers wherever they end up...... Why I didn't think of this to begin with is beyond me. it would have made things much simpler

Dude, are you made of leprechauns? Cause that was awesome!

I thought your original plan for the deep columns was because you wanted to have the option of installing subwoofers or MBMs in the columns which required more than 8" of depth.

Looking forward to seeing your acoustic plan!!

I can't get anything past you guys That was the original plan. If I decide I need a sub in one of the columns, I can cut a hole in the wainscoting for it to go into. MDF is easy enough to patch if I decide I need to move things around. I fully expect even bass response to be an iterative process.

You may find getting smooth response across all seating won't be as hard as you think. One S2 was fine for a few seats.........but going to four UXL's at 1/4 space yielded results +/- 2 db's variation from all seats. With single S2 I was looking at +/- 6-7 db's...........

It all depends on room........




BTW, what happened to the SEC, especially the SEC West?

Pac-12 is consistently overlooked while playing the best football in country.............in the last 10-15 years I can think of four situations were best team was in Pac-10/12 and was left out of NC game! Go figure..............

I'm still leaning towards lilwreckers. I don't know how many though. I can get two in the front without issue, but getting any in the back is going to be a problem....... Hmmmm..... Let's see what you guys do with that.

You have *some* available space in the back right of your theater where you could easily integrate a pretty sizable sub box.

You could also consider a shallow depth dual driver sub box of the appropriate cubic volume at the back center of the room with just the slightest bump-out, similar to what Moggie did in his Old Vic cinema, only with lower profile subs.

Just spitballin' here....

I've definitely got room in the back of the theater for more subs. I don't think I have room to get another large folded horn over the wainscoting and back into the corner, though. Once I've built the first two, I'll have a better idea of what I can fit in there.

Keep spitballin'! You never know what will come up!

I thought I would put together a quick TMcGoogle® Sketchup of @Mfusick 's proposed rear wall subwoofer plan.

This is just the full rear wall elevation, but the left and right walls are very similar....

I know you liked the horn solution. I still think I would go with several large ported cabs, all tuned the same.

Weak sauce, and boring... and that distortion HORNS kick ass. Horns up front and some sealed in back (because of size) makes more sense.. you gain extension and the balancing that multiple subs provides- and keep that awesome horn SPL and dynamic range.

I drove by your house today JPA. I started to stop by and say hello but I figured you were downstairs hammering away at the theater so I didn't want to interrupt the progress.

I'm really falling down on the job here! It's possible I was down there. I've actually been moving a little dust around down there over the past few weeks. When's your theater going to be up and running? I see you've been making progress.

I'm really starting to get the bug again. I've started looking into subs in more, which is something I swore I wouldn't do until the room was finished. The subs are probably one of the things I've been most looking forward to. At any rate, it's really getting me excited about finishing up the project. Here's the progress so far:
  • I've (finally) sent Nyal my updated layout, and he's working on my acoustic plan. He wanted me to make a couple simple tweaks to my previous "final layout"
  • I've managed to take out three of the six columns that need to move. Patching the wainscoting should be relatively simple.
  • I've ordered my front row of seating, and my wife and I have decided to move our living room couch to the theater for the back row until funds allow for more theater seats.
  • Overhead lighting position is finalized. Once I get my ATMOS speaker cabling run, I'll finish up the lighting up there.
  • I've wired up the receptacles in the front of the riser.
  • I've glued together the boxes for three of my six Volt-8s minus the baffles.

Anyone have suggestions for caulk to use on the inside of my surround boxes? I used Titebond to glue them together, but I'd like to run a bead of caulk around the joints for a little added security. I've read in the past that Latex caulk off-gasses acidic acid as it cures, which can be harmful to the speaker cone and surround. Any thoughts? I'll use PL when I attach the baffle since I can't get any caulk in there once it's on.

Dude, are you made of leprechauns? Cause that was awesome!

Great to hear about progress.......

As far as caulk........... I would look for some form of flexible caulk. What's great about acoustic caulk I sourced from Soundproofing company............seals, and is very flexible.

I am about to start building the boxes for the subs and probably order them soon. What were you thinking about going with for the subs? I am ordering 16 SI 18's so if you chose anything SI I am sure we could get a nice price break by ordering more.

I had read that about the caulk too, but at some point someone showed me a link proving it was bunk. In either case, I'm pretty sure the people who say you need to be careful about the gasses say that a few days of setting without a driver in the box is sufficient. So, if you want to use caulk go ahead and give it a couple days to cure before you load a driver.

I mean, you probably have a couple days of finishing work to do anyway, right? So make it happen.

Good to hear you're back at it.

Parts express sells some acoustical sealant caulk specifically for speaker builds. That, plus some adhesive weather stripping stuff for the back of the woofers is a great idea. Some speakers of kits include that, but a lot don't.

I'll email you a pic of it when I use it this week. I got some and I'm balls deep about to use it.
