4.72"x4.72"x9.6" Sale Acoustic Foam 16 PCS in Black Bass trap Soundproof foam

These are nice and a good value for the money

Really works! I have this pocket where the bass bounces like crazy and just putting these 16 did wonders. Also no issues with the decompression. Did not need to soak. They were perfect a few minutes after opening.

I put just a few of these in the corners of both HVAC closets, under my staircase, in my laundry room, and in the guest bedroom closet. They're not magic, but if you understand how low frequencies interact with large structures, a couple of these can make a huge difference in the right place.Like others here, mine did not come with adhesives, so I just set them either on shelf or floor corners.

These are entirely too small to actually absorb bass frequencies properly. It's a ripoff and false advertising. Do not get.

Final touch fir corned to absorb excess noise

These things are a joke , tiny , deformed and won’t stick to any adhesive at allComplete waste of moneyPosted a photo of it beside my REAL bass trap

Tuning a series of practice rooms in a music store…Used these as bass traps in the smaller rooms. They served the purpose and helped with this job.

To say quality control on this is bad is probably being complimentary. For sake of brevity, I'll cut to down to bullet points:- The pieces are cut from a single block of foam, and the cuts are horrifically inconsistent. You can not, for example, stack two of these on top of each other and expect them to align visually - not even close. Width and depth also vary by ¼-½".- Foam density is not remotely up to the task of bass trap work.- The size is inadequate to serve as a truly effective bass trap, but this was known, so just keep it in mind (I note it, but didn't mark my rating down for it.- Some cuts are not even complete - for example, two pieces of mine are still attached at the long end by enough foam that it will be a challenge to separate them with a clean cut that doesn't look obviously different from the other pieces.For me, I wasn't expecting great performance out of these - I knew ahead of time the size made them almost laugable as bass traps - but I was hoping for something that would provide a little bit of help in the corners and provide some visual consistency with the read of my booth. These are so inconsistent in the way they line up that they only offer value if installed with separation, but their acoustic impact is so minimal as to not be worth that.In short, save your money (even if it isn't a lot of money).

The media could not be loaded.  Product as describe. Only downside was packaging because it's air sealed, sponges were compact. Found easy solution, putting sponges, under hot water made them expand in seconds. After drying on radiator, sponges are like new !

Diese Akustikschaumstoff mini Bassfallen sind sehr schlecht verarbeitet, wie man auf dem Bild sieht keine gleichen zu finden verzogen schlecht geschnitten und dadurch nicht zu gebrauchen!Bilder sind nach 2 Wochen rumliegen entstanden, mehr Entfaltung ist nicht zu erwarten, liegt nicht an der Vakuum Verpackung !!Mangelhafte AusführungSuper bad Quality!

considering its not name brand these are solid to keep all unwanted noises out, ordered twice to fill my recording space

Not unusable if the look doesnt bother one

Risolto il problema del riverbero che avevo nella mia stanza insonorizzata. Peccato che sia disponibile solo un colore
