Correct. You can just leave air behind the cloth up high. Some people also like to alternate slats to make a pseudo-diffuser. It's a lot of work and can actually cause problems if not done right though.

Would this diffuser just look like, say, furring strips oriented vertically with even spacing, or some such?

Re: The RanchHT


Sorry for the late reply. Been in Denver for RMAF all weekend. Pulled in at midnight last night.

Yes - vertically oriented strips following a specific sequence. Try using the QRDude page that's listed in a thread in this section. There's a calculator there. Just use 1" for the depth and probably a 5 root sequence.

Re: The RanchHT


More developments.

Putting up the furring strips and OC703 takes WAY longer than I thought it would.




The back wall is still going. I'm doing 3" deep OC703 over the whole back wall, so those furring strips are a lot deeper than they look.




More shots of the front wall:






Bryan: if you get a chance to read this before I email you.... what should I do with the door(s). In particular the one that probably sits in a FRP on the right of the theater.

1" thick OC703 panels?

Re: The RanchHT


Do what you can on the door. Do the same thing that's on the wall in that area. Most likely 1" but as high as the opposite side.

It's a DIY sub.

The driver is an IXL-18 from Mach5.

Yup. I'm not sure if you have my stuff handy or not, but I want to confirm how far back I should do floor to ceiling 1".

If you can, shoot me an email or a PM.....thanks.

The whole stage is a bit bigger than it looks in the pictures.

The Sub is 4 feet tall, with a footprint that is 2 feet by 2 feet. Lot's of internal bracing.

I'm not sure if I'm supposed to post links over to the other forum, but if you google "IXL 18 meets the Easy Button" you will find the build thread.

It's a pretty beginner sub, actually, and you may be able to do better with the driver if you have more advanced woodworking skills. On the other hand, it destroys almost any retail sub that you can buy.

Thank you. I have a SonoSub already, but I'm planning for the future .... I'm dreaming to have a room with 2 SonoSubs 15" (front) and maybe 2 boxes like yours with 18" (back)

That might be a huge pain to tune.

But I'm no expert.

Re: The RanchHT


More progress:

I finished much of the treatments this weekend but ran out of OC703. I need two more bundles to complete the bare sections.

I started putting up the fabric on the walls. Cutting takes a LONG time. Longer than actually stapling (that Porter Cable stapler is awesome).

The fabric is black Dazien Celtic. The pictures make the whole room look a lot brighter than it actually is. The Dazien definitely soaks up the light, without looking totally flat. I'm really happy with it.








A pic with the flash on indicates more the batcave feel to the room:

Re: The RanchHT


To do list:

1. pull off doors and paint hem
2. Install treatments on doors.
3. Shop for trim: chair rail, crown, quarter round, baseboards
4. build screen wall
5. build screen and surrounding GOM frames, with velcro
6. Build and install columns
7. etc. etc. etc.

every step closer seems to create 10 more things to do!

Re: The RanchHT


Bryan,

would you put treatments on my subwoofer? That's a lot of reflective MDF up there.

Re: The RanchHT


Well, never done that before but looking at the size of the sub, it might not be a bad idea - at least on the front and sides.

Re: The RanchHT


I started building columns this week. Pretty annoying project, actually.

I decided to go with a relatively simple design. All fabric wrapped frames.

I have two problems:

1. The box frame I made really obscures the drivers for the speakers. I think I may create a design that mimics the angles of the speaker, and make the column deeper. Then the front vertical supports can be in front of the speaker, rather than behind. I don't like the idea of a deeper column, but it will have to do.

2. An all fabric columns would be susceptible to someone putting their hand through the fabric. Not ideal. Perhaps I could include more structural members into the framing to protect it.

Re: The RanchHT


Outstanding. Great way to impement it. Fill the columns with insulation of some sort and you're good to go.

Re: The RanchHT


Bryan,

Do you agree that I have an issue with one of the 2x2s blocking the tweeter?

Re: The RanchHT


And if the columns are just fabric wrapped, with nothing inside, do I need insulation in them?

Re: The RanchHT


Well, I'd like to see them a bit more open if possible (tweeters). Honestly, they're pretty directional so not a huge deal - just general principle.

You can just leave the columns empty since there's nothing to resonate if you want. Just a good place to get some additional thicker absorption in the room.

What about using those perforated panels from floor to 5'??? ....then fill the column with fiberglass (as Bryan mentioned)

Re: The RanchHT


Another way of doing it so your speakers are completely free of any framing, is to use your existing framing from the floor up to the bottom of the speaker..There you cut the framing off and fit a top to that part of the frame..
Then make a separate frame, coming down from the soffit to the top of the speaker, with a bottom timber panel fitted to that..
Basically your speaker is suspended between the top and bottom frames in free air..
Then the whole framework is covered with your acoustic cloth..
To all intents a purposes, it just looks like a solid column..

I hope I've explained that clearly enough for you..
