I considered that and have four Acoustic Elegance IB-15's...maybe down the road.
My sonic temple...new listening space under construction

I predicted the ceiling would be a challenge and, unfortunately, I was right. Fourteen hours to get not quite half covered. Each panel is 4'x5' and gets stapled to furring strips that are installed over the rafters so the fabric doesn't compress the insulation and also to give me something to secure to on the longitudinal axis.

About ten hours into it, I decided it's time to redeem some favors owed to me from friends for the second half!

you're getting the same bass trap performance from the 3" rock wool as from the bag traps?
That doesn't seem right.
I just need to nail some of this stuff down before I start banging nails on my (more modest) project.
Also wondering.... if 50+" of rockwool becomes low frequency reflective, I wonder how 3":.. space...3" would perform.
My space as it sits now has a bass suck out - I need to tame the room & that is a planning parameter.
Like the fabric wall & ceiling treatment. I was considering that my self.
Weather is cooling off - you'll be nailing that temple down soon.
Big project for 1 guy.

Yep...it's A LOT nicer working out there now that the stifling summer heat (which lasts into early Oct) has subsided. I got in a groove and was making some pretty good progress until last weekend when I had to go out of town...and this weekend I leave to go out of town again so I'm champing at the bit to get back out there.
To answer your question, no...the 3" rockwool will be doing good to get below 250 Hz. It's absorptive down to approx 200-225, but even down that low were talking about a coefficient of around .7...the minimum value for effective absorption. That segment of the back wall is meant to be more mid/upper bass trapping. I really have put a lot of effort into getting mid and upper bass totally inder control as I feel that's a critical area for clarity. My experience with prior listening spaces I've tuned is that getting the mid and upper bass well controlled tends to bolster and improve the mid range...which in actuality is probably simply because it's eliminating distortion that otherwise imposes on mid range clarity. Anyway, between the rear wall and entire ceiling...which is over 600sqft of surface area acting as a mid/upper bass trap...I should have that region well controlled.
The limp bag traps are good down to 80-100Hz. I'll measure the room before I attempt any deep bass trapping to see what the problem frequencies are, then build membrane traps that address the specific frequencies that are problematic. It's extremely difficult...if not impossible...to deal with sub-80 Hz energy using velocity type absorption (porous) devices. For that region, the most effective device will be pressure type (membrane). Fortunately for me, there's a very good chance most of the really low stuff will just pass right through the walls since I don't have any exterior walls that are masonry.

Thank you for the journey, watching and waiting for the final result.

.My chips are on me getting about 90% done and stopping.
Old saying we often quoted back in my working days:
The ninety-ninety rule:
The first 90 percent of the code
In computer programming and software engineering, the ninety-ninety rule is a humorous aphorism that states: The first 90 percent of the code accounts for the first 90 percent of the development time. The remaining 10 percent of the code accounts for the other 90 percent of the development time.
If the sonic temple follows the ninety-ninety rule, since it started in September of 2021, it will probably be "done" somewhere around early fall of 2024....

Well, fortunately the wife is starting to ask "are you close to finishing the studio so we can get all the big speakers out of every other room in the house?"...so I'm getting encouragement from where it counts most!

Well, I've not gotten the moratorium on the honey-do list that I requested, sooo...
The boss has put her foot down. It's better than where she'll put it next!
Hear hear!
I don't know how I missed this thread.
Your project, and the pace, reminds me of my own porch that I'm doing on a budget (utilizing all sorts of freebies, roadside finds, etc) and by myself, mostly.
Yours has a much grander goal than my own, but many of the pains you're dealing with, I feel in my bones.
Hang in there, bud. It's looking phenomenal, and should be not only a sonic temple, but a respite from the world's madness.
