Looking for a few opinions...
I have a chance to purchase some used room dividers, the type you would have seen back in school.
I have been looking for something similar for a while and its hard to pass up at the asking price.
There are 3 available, 2 standard height +/- 48" and a single tall unit around 72" tall.
I'm considering placing the 48" tall units between my L/C/R at approximately the 1/4 room width locations and the tall unit where there should be a backwall if I were following ideal room dimension suggestions.
These are cloth covered with a soft core of some type.
I'm hoping they will act as bass absorbers and tame room reflections.
Thoughts?

Be prepared to have to bump up your amp's gain. I recently put Serenity_then's panels in my main A/V space and found I had to turn up my Onk's gain from -15 to -10 to achieve the same SPL. That represented a peak RMS level of 40W into the M5s for the song I had on. I experienced improvements in image focus and depth which I didn't expect given the already terrific soundstage I was experiencing with the M5s.

You may also want to try diffusers. I'll be experimenting with those soon as I settle on how to best make them.

I wouldn't. We dont do pure absorbers anymore. For reasons Mojo hinted at.

If you can get them for almost nothing take them to learn from. Experiment. Be methodical. Have fun!

I'm gonna make some diffusers out of cheap dollar store cardboard similar to the ones you made for the interrogation room.

What kind? Polys?
Posted By: Mojo Re: Room dividers - 11/03/18 11:10 PM
The kind that looks like a half cylinder. You can make them out of cutting a sonotube in half but that takes more skill than I have. smile

Try embedding a plasma in one!

I'm building a multi-phase, tessaractic magnetic containment field of Langrangian order 2 in the 40W range.

Ok. Wear safety glasses. smile

I have seen a lot about diffusing rather than absorbing lately.
$20 each if I can get there first though.
I was thinking the rear would block alot of the fan sound I hear behind me (my electronics are stacked about 3' behind the MLP). If the tall unit fits below the projector I'm sold.
I like the 1/4 room width position because it will work. I'm still following the V2 layout except for my rear surrounds and subs. Nothing in my current layout would need to change but it might push me to slide the screen back so its only 4' off the back wall again.
If any of them do damage they can go upstairs in our rediculusly loud/reverberent living room.
Wish she'd confirm if I can pick them up tomorrow. Pretty sure they'll be gone by my next day off.

I'm considering making my own diffusers to.
Not sure what to do exactly.
When I do decide to save the money I ussually regret not buying the good ones, regardless of what said item or service is.

Edit: I'm still trying to achieve the best of both worlds in my theater.
Music is pretty impressive/ nice when you find a good recoding.
Movies and games are also high on the priority list and right now my biggest gripe is I'm at the closest short throw recommendation for my projector which happens to be at the minimum viewing distance for my screen. I've never had so much moire before. On my favorite game there is artifacts when I move around but the image is pretty friking nice.

I have plenty of headroom.

Here is my 4-step plan for you:

1. Sell all your gear.
2. Delete all photos of your gear.
3. See a hypnotist to wipe away all of your A/V memories.
4. Buy a Fire tablet for A/V.

You'll never have these kinds of problems again!

No deal.
I already spend more time on my ipad mini than I do in my theater but thats somewhat besides the point.

Well she seems to be ignoring me so it doesn't matter.
Maybe I'll take my few bucks and buy the Spears and Munsil v2 calibration disc.
Posted By: Mojo Re: Room dividers - 11/05/18 10:09 PM
How about upgrading to v4?
Posted By: brwsaw Re: Room dividers - 11/06/18 03:02 AM
V4 speakers?
Already have HP V3's with V4 tweeters.
I am liking the idea of fully active external cross overs though...

I've picked out $10 worth of dollar store parts to treat my 4200ft^3 space. Poster board and string to make cylindrical diffusers, shelf liners and paper lanterns for ceiling diffusers and floor mats for wall and ceiling absorbers. All strategically placed per MATLAB solutions of the wave equation.
