Acoustic Panel Gray | Fiberglass 2-pack | Professional sound absorbing Panel | Decorative sound proof panel | acoustic wall panel (36x13x2 in) - Gray

I've had no problems to install and am pleased with the results. It looks great and is serving the purpose of absorbing sound during virtual meetings and as a bonus my home theater sounds much better now! I can tell the difference before/after. They have a metal frame inside, sturdy product and excellent finish. PS: I am thinking of buying a few panels for the ceiling. I would have to buy the installation hardware. Ceiling hardware is not included in the package.

Very impressed with the quality. They are well made, and just picking one up and holding it in front of my face while speaking it was like the sound was instantly disappearing! Great absorption. They are lightweight and easy to mount. Hung them over the stations in my salon to help reduce the echo and noise level during busy times. Between adding these and some more furniture/decor item, we greatly improved the noise level and sound clarity in our salon. I may add a few more later since these work so well, if we still desire more improvement. I was skeptical if the panels would make a big difference but they definitely do. Your mileage may vary based on the room and it’s needs , but I would recommend these whether you need just a few or many!!

Very well made l mean very well made look nice on wall it’s nice to buy a product that was built with care and looks

Decided to convert my office into an amateur music studio and these panels were part of the whole project. Covered the windows with 2 layers of blackout curtains and hanged these panels on the side wall and it has achieved the result I was looking for. The echo is gone. Instead of drilling holes in the wall, I used 30lb Gorilla double sided tape. It has been a few days and it is still there. Sound Panels were placed strategically according to my Amps and speakers, avoiding main reflections. Enjoying myself playing guitar and recording in the end of the day.

cheap junk. don't waste your money. they fell down almost immediately and they are very poorly put together

Product works as advertised. Engineered well and actually work! My music room has 6 of these now and it’s Really quiet now. No more sound reflections. 🤙🏻😎 On the pricey side but great product!

The Z-clips are shown in the side photos but no Z-clips were included. Ended up ordering them from a company that specifically sells them. My son is waiting for the hardware then we can update with a review of how well the product works.

For my office system I have a high end set of NHT powered monitors and a B&W powered subwoofer that sits under the desk. The problem has been echo and reflective bounce from the opposing wall. Especially annoying on Zoom calls (my mic always has a toilet bowl echo) on recordings. Problem solved with the Tönnen panels. PROS - Immediate sonic improvement (no bounce or echo) - Color options - Easy mounting - Love the logo CONS - Needs some scientific measurements to define what frequencies are being affected and what distance. - Panels should be pre-packed in polybag to prevent dust. - Need some social media presence (I posted but nothing to tag. Contact me for link).

Well finished product for the price. The beveled edge dresses it up while keeping the overall look very simple. Improvement to the sound from the front speakers of my theatre system was immediately noticeable. The panels were mounted at 1st reflection points on the wall. Voices and instruments were crisper, clearer and more natural sounding. The 2" panel will definitely absorb a wider range of frequencies than the thin, stick-on panels. The website states that the NRC (Noise Reduction Coefficient) is > 0.95 on average. I'm happy with my results!

Didn't do any data collection or any kind of tests on it but as anecdote for my personal experience I noticed a least some improvements when listening to music with my studio monitors in my master bedroom. And I think these are esp really great when on sale, which I got.

Quoi dire de plus , très bon et beaux panneaux, très content de mon achat

Helps keep the noise level down in our small restaurant

Noticeably different on and off the wall.
