Very interesting approach to pure function. I'm curious how the cylinders are constructed. Cardboard shipping tubes covered in some absorbent material? Industrial insulation wrapped in burlap.

Check out “sonotube”, thick cardboard tubes used to form concrete.

And it's absolutely AMAZING how different the TA-100 amplifier sounds warm vs. cold. Cold, the amp sounds like a REALLY cheap AVR (or maybe a transistor radio). But let that puppy warm up, and it sounds GLORIOUS! No kidding.

Today, I coated one of my 2' x 4' x 8" wooden diffuser panels in teak oil (so called). Tomorrow, I'll do the other. My audio amigo claims that his diffusers have worked best when placed BETWEEN his speakers (I've never tried mine there before). Once the teak oil dries, I plan to install self-adhesive felt sliders on the long edge of the diffusers & set them along the floorboards between the speakers.
Of course, for the diffusers to work between the speakers, I'll need to move my equipment rack off to one side or the other. This will entail some PITA concerning lengths of HDMI cables, speaker wires, coaxial cable wire, and subwoofer interconnects. Sigh...
I'm also considering using "soundproofing curtains" on some of my walls, and maybe installing full carpet with a thick pad in the listening room. Once those changes are in place, maybe some acoustic tile over the sheetrock ceiling?
UPDATE: Yeah, I got the second one oiled today & tried to bring it in but had two insurmountable issues:
1. Wife didn't like the smell - out it went again
2. I need longer HDMI & TOSLINK cables before the new location will work. They're on order from Amazon, but who knows when they'll get here?

Per my audio amigo, I moved my two diffusers (2 feet x 4 feet x 6 inches) from their previous (mostly random) positions to an "on the floor, between the speakers" location. And? WHOA - I think that this made a HUGE difference in the sound. LOTS more midrange definition and less midrange overload (although the floor-ceiling problems of my room are still there). This definitely made a difference, and a positive one.

My audio amigo built some adjustable stands for Altec Lansing computer speakers - they sound better than expected...

OOH... I think I've found an integrated amp that may come to visit somewhere down the road - PASS Labs INT250:

Not mine to do.
Wires bother me - not my audio amigo.

Contemplating speakers. Contenders:
1. KEF Reference 1 bookshelf & Emotiva Airmotiv S15 subwoofer - On the plus side: Point source imaging / Can be listened to fairly near-field & moved against wall when not in use / High quality control on drivers & cabinet. On the minus side: Require stands / Cost $4.5K even on the used market / Volume limited / Require electronic crossover & sub
2. KEF R3 bookshelf & Emotiva Airmotiv S15 subwoofer - On the plus side: Point source imaging / Can be listened to fairly near-field & moved against wall when not in use. On the minus side: Require stands / Cost $1.5K even on the used market / Volume limited / Require electronic crossover & sub / not as refined sounding as Reference 1s
3. Dahlquist DQ30 floor-standing speakers & Emotiva S15 subwoofer - On the plus side: Time & phase-coherent with excellent imaging / available for $1K used / Unlimited dynamics. On the minus side: Drivers may need repair / Require electronic crossover & sub / Too heavy for movement and may need to be positioned where imaging is less than ideal.
4. Tekton Design Double Impact speakers - On the plus side: Sufficient bass response that sub & crossover aren't needed / Unlimited dynamics / High sensitivity makes amplifier matching less critical / Warranty included. On the minus side: Cost $3K and are not generally available on the used market / Not time or phase coherent / Too heavy for movement and may need to be positioned where imaging is less than ideal / Lowest WAF of any other choice.
5. Magnepan 1.7i speakers & Emotiva S15 subwoofer - On the plus side: Transparent sound with broad imaging / Available new or used for reasonable prices / Can be listened to fairly near-field & moved against wall when not in use. On the minus side: Require electronic crossover & sub / May not work in smaller (future) rooms / Particular about amplification

I recall having a set of those Altec Lansing powered speakers hooked up to my Apple II GS. Unless I am conflating my tech memories.

My audio amigo says I should skip speakers, keep the Airmotiv T2s that I have, and spend the available $3.5K all on room treatments. Although non-intuitive on the face of it, the recommendation has a good bit to favor it. My listening room currently has sheet rock ceiling and walls, and a plank floor over concrete. If I do installation myself, I might well be able to carpet the room and install acoustic ceiling tiles for the same $3.5K. The negative of investing in the room is that it's money that provides value only so long as I'm living in this house. Should I move in the next five years, that money is non-recoverable.
Would treating the room provide a greater sound quality improvement than new speakers? Yes it would. But better speakers are portable assets and would be transferrable to a new house should we move.
With global warming, a vintage and ill-maintained levee system, increasing numbers of ever-more-powerful hurricanes, a third-world-quality State economy, and our only grandchild located in the Northeastern part of the country, we're thinking ever more strongly of moving while our existing house is at maximum value. My work skills are portable, and would be salable in any part of the country, so there's no huge impediment to moving there. There are no remaining close family ties keeping me here either.
Yet agreement on where we might choose to relocate is elusive. Wife wants a State that has generous elder care and not too high a cost of living. She wants close proximity to medical care, groceries, and drugstores. Those are desirable qualities, but some of the choices she's voiced (Atlanta? Really?) are of absolutely no interest to me. Our daughter suggests Rhode Island, but again, I'm not familiar with the State at all. Further, having lived my life in the less-frigid climate of Louisiana, I'm not sure I want to learn the joys of shoveling snow at my age. Suffice it to say that the relocation decision is fraught with procrastination. And the effect of all this on audio choices is murky in the extreme.
Sigh...

I live in little Rhode Island. Lived here 47 years now. It's a nice little state. Having the 4 seasons and no destructive weather is a plus too!

It's high up, so no risk of flooding. A hurricane only reached us once, but it was pretty mild by the time it got hear. Winters are not very harsh at all typically, and if you do need shoveling done, there are plenty of locals that offer services. You are within 30 minutes of everything Cinci has to offer...from our vibrant downtown to every major part of town you might want to go, as well as some of the finest medical facilities you could hope for. Cost of living is pretty low (property taxes on my 4500 sq ft house are $4000/year), and crime is low. But the real bonus is that every summer, you can get Burwinkel's sweet corn fresh from the farm and many other fresh veggies and fruits from various local country markets. Mark

Also many houses are set far back from the road. Mine is 350' to the road, so we have a nice, secluded place to sit and have morning coffee. This is the view from my front door. (Yes, the grass needs cut...been re-leveling the stones in the walkway this week, so grass cutting took a back seat to that work) Mark
