ATS AcousticsSound Absorbing Noise Dampening Acoustic Panel Wall Treatment 24" x 48" x 4" Beveled Edge (Black)

I purchased 18 24 x 48 x 4-inch acoustic panels in Ivory, and my studio is dead silent. I am highly impressed by the quality, considering the great price, fast shipping, and excellent packaging. I highly recommend it.

I bought my first ATS panels many, many years ago. By way of full disclosure, note that I have designed and helped build recording studio's for friends, since the 70's, and have had a side hustle of sorts designing high performance speakers over a wide cost range for the last 3 decades. Sadly, room acoustics and behavior are one of the most commonly ignored factors in a home sound system, yet one of the most modestly priced in comparison to the returns gained.This particular set was bought for a specific task, the development and testing of a theater grade center channel system for a home front projection client. But while this "client" will use some in the recommended positioning for the CC, it's even more important that he add more of them to reduce high level side wall reflections on his mains speakers and the resulting comb filtering effects at the listening positions.It's all about the physics, folks, and I use a calibrated measurement system with specialized software to evaluate before and after. (Earthworks M30 + Motu M4 interface, with RØDETest acoustics software).I don't like the hanging hardware on these newer versions of ATS panels as much as on my old ones, but it gets the job done, and comes with paper templates for marking the wall positions. You need to be a bit "handy" to install- if you can hang a storage cabinet in your laundry room, these will be a breeze.with the off white fabric, the esthetic impact is minimal in any negative sense- I don't like looking at open cell foam panels on the wall. Some people think that's OK and cool and "techy", but it doesn't work for me. The absorbency of the ATS panels is also better over foam, in my experience, over a wider frequency range.

Ordered two for a test run and will now be using these to equip my room. Excellent build, broad frequency response, good stuff 🤘🏻

One of the best things you can do to a home theater or music room is to hang acoustic panels such as these. Acoustic panels like these quiet the reflections that color the room's sound. Size matters and these are the thicker 4" deep traps that absorb a wider frequency range than the more common 2" thick panels.When treating a room try to treat the areas where sound would reflect from the speakers, off a wall, ceiling, or floor and then into the listeners ears first. Then you can address other reflections like those off the back walls.I bought a pair of these 4" thick traps to hang in the back of a dedicate music room. Up front by the speakers I have pretty panels with art printed on them that cost several times the price of these. These are great value panels as the quality of the fit-and-finish looks great installed.The panels include "French cleats", metal Z clips that mount to the panel and wall. Screws were included.

Making these guys yourself, if you haven't already done the math will be expensive. It is important to know that you will need a drill and a few small drill bits. It works better when you place the template on the panel and drill very small holes for the screws. Know that the plywood is thin and so you need to be very careful when screwing in wood screws to not strip them. The Z straps worked great. Each one will take about an hour to install. Would Recommend. Thanks ATS!

The fabric on the outside is a rough tweed which is pulled in many areas resulting in balls of fabric sticking out all over.They were also covered in some white short hairs (looks like cat hat but probably synthetic). I expected way more quality for the price.

After hanging up the "bass traps" and running my receivers calibration program (MCACC) the receivers' numbers changed a bit. However my receiver noticed more of a difference than I did.These are my first "bass traps" so im not sure what kind of effects im supposed to get. I'll have to do more research to get a better idea of what to look for in bass trap performance because right now I can't really tell.UPDATE: 5-2-12After resareching the subject of "Bass Traps" to death, I have found many things in common required to make effective bass traps, and these acoustic panels have almost none of them, so im currently in the process of building my own traps. This should be good!!!

Absorbs lots of minor sounds (Air conditioning, utilities, general room tone) and echos from speech and computer speakers. Great improvement for a home office.The Z-clips included for mounting seem sufficient, but I did not want to punch more holes in my walls. ATS even includes large paper template to make mounting with the Z-clips easy.For a removable mounting option, I recommend buying some D-Ring hangers and using some heavy duty Command hooks to mount these on your wall. This unit is fairly heavy, so be sure to use multiple hangers (check the weight capacity of your Command hooks!).I ended up purchasing three more of the 24" by 24" panels that ATS makes for use around the house -- glad I did!
