UMIACOUSTICS 2 PCS Acoustic Panel, 47.2" x 23.6" Fiberglass Sound Proof Wall Panels, Sound Absorbing Panels for Studios, Office, Home Theater. Charcoal Grey

Thse panels are well made. The fabric is attractive and installed perfectly. I especially liked the system for hanging the panels. They come with all the necessary hardware and I found it very easy to install.As far as performance, I bought 4 panels for my 11' x 22' room and it tamed the overly reverberant room. Before the panels where installed, my hi fi rig was unlistenable. I have 2 area rugs, 3 fabric chairs, a large bookcase with 650 records and various plants. None of that tamed the echo I was hearing nearly as much as these panels.For reference, I previously had my hi fi set up in another smaller room that was very well damped without acoustic panels. The current set up sounds just as good.Definitely worth the money for these well made panels.

Originally gave 2 stars because the packaging did not include the wall brackets and hardware. After contacting the company, they provided the brackets and hardware shortly after. Easy and efficient. I change my review to 5 stars because of the quick and understanding customer service.2/5: They look and feel high quality but there were no wall mounts included in the box. Only the panels. I can't put them up without the wall anchors.

Panels are well constructed and good for damping reverberations. I use them in a small practice area in an otherwise very live room. Given that there is only a small part of the room where they are used, I can still hear the difference and I’m satisfied with their performance. I had them professionally installed, as I am not good at that kind of thing. About 40 minutes to install, $50.

Excellent. Very easy to hang/install. E are using in our church sanctusary. No adhesives. Required. Comes with a template to hang on wall, drill at the marked hole positions, install the bracket to the wall, hang the panel.

Ordered 8 sets for our school gym. Good quality. I like that they come with hanging brackets versus many other brands come with double sided tape. The cardboard template included made them easy to hang.

The media could not be loaded. I purchased 8 of the 24x48 in. black panels and the quality of the fabric and fiberglass board are high quality and great price. I mix and master music and vocals and needed something that looked professional, had the functionality to help with sound reflection lowering it to a minimum, and take control of the sound giving me and honest sound from the speakers and these do exactly that. The install was fairly easy due to the template provided showing where to drill the holes for the brackets. Hanging them on the bracket was a little tricky at first but not bad, I was able to hang eight of them in about an hour. These did not have any weird smell. I would recommend these to anyone looking for sound control in a studio setting. They look and function great.

I originally bought the pair, I liked them so much, I bought two more. I no longer hear the random creaks my house makes and my speakers have never sounded clearer. They're very light and easy to set up. I heavily recommend.

I waited nearly a month to review this, in order to get a better idea of how well they work, including at a large (and therefore noisy) Thanksgiving gathering. After that extensive time, we still can't say with much confidence that they are effective IN OUR SITUATION. I emphasize that because we have an open design kitchen/family room with vaulted ceilings, hardwood floors, and wood window shutters--pretty much a perfect recipe for booming and echoing. And one of my more significant complaints is that the seller provides zero advice for how many of the panels you need to use, even as a general recommendation. My guess is that the four panels we received are simply overwhelmed by the acoustics of the room. But how many would it take? 8? 12? 20? That would get real expensive real quick, and without any assurance that they would be effective, that's more risk than I'm willing to take.That said, these panels seem well constructed and look pretty nice. Although the box says they can be applied with superglue (!!), they in fact come with pretty hefty metal brackets. The brackets seem like overkill, but better that than superglue! Though since these are likely to be mounted in awkward locations (ceiling, high on walls) drilling and mounting the brackets could be a pain (although placing the panels on the brackets, once mounted, is easy). But what's missing is a template--the instructions suggest outlining the bracket against a piece of cardboard to create a template. That works, but these are not cheap, so it doesn't seem like too much to ask to provide a template.All in all, these are probably a "3" for our situation, but I'm giving a rating of "4" because I suspect that they could be much more effective in a smaller room. But from the research I've done, it seems that proper placement is really critical, so the lack of instructions is concerning.
