TroyStudio Bass Traps - 12 Pcs 4 X 4 X 12 Inches Dense Thick Studio Bass Foam Corner, Acoustic Treatment Panel Absorbing Echo Reverb, Low Frequency Sound Absorber for Music Room Home Recording Studio

The sounds in my bedroom were very loud and sharp (I have a shepherd that believes sharp, high pitch, very loud barking is the best way to communicate when you don’t read her mind immediately). Bought a pack of these and put them in the corners (one at the ceiling and one about half way down in each corner) and it was immediately night and day. Had a few left over for my mom’s office too, which was great. They’re easy to install (I think I just used a little of that wall putty), affordable, and they’re not massive which is great.

Great quality. They work well.

If your intention is to use this product as corner-wall-ceiling bass trap, I would not recommend this product as it does not measure out to 8 inches. For the advertised product (i.e. Periodic bass trap), I guess this does the general job when placed between just a location between wall and ceiling, or a corner of just two walls meeting together. For corner traps, I highly recommend the 12"x12"x8" bass traps and use these where needed between two-points only. I have made an investment in this material and several other products that will work in concert. I have roughly a 600 SqFt sound recording studio I am preparing and chose this product for the main area to stop sound and frequency from bouncing off the wood-panel walls. I plan to use these traps in several locations. Another issue I have with the product is about 20% of the tiles that I ordered in packs of 12, are not all decompressing and take a lot of work to form into their final shape. Several tiles never have fully decompressed, no matter what I do (i.e. submerging in water, blow dryer, etc.). It almost appears if several of the tiles were smashed when compressed into their packaging. I am not a fan of submerging the product into water. If any water remains in the material air pockets, over time mildew will form and would be accompanied by smell. I have tried the water submersion and dryer technique, but caution anyone considering this approach and to not use high or mid heat, if using a clothes dryer.

Excelente product

Sorry but these are WAY too small to call them "bass traps. They did nothing.

Si muy prácticos

For the price it gets the job done. I’m glad I went with a 4 inch though as opposed to 3 inch and this phone has a at least a design that’s not just pyramids or triangles. Doesn’t absorb a ton of sound. 3m doesn’t stick to it we had to super glue pieces of paper plates to the back and then let the 3m strips stick to that.

Es exactamente lo que dice ser. Pero son más pequeños de lo que creí. Realmente no son muy útiles como trampas de graves, pero sí para las esquinas. Pero les doy 5 estrellas porque son exactamente el producto que dicen ser. Yo aconsejo trampas de graves artesanales y de otro material.

Half turned up out of shape - even after waiting hours to see if they would expand they were still wonky..

Son esponjas suaves de mala calidad en material y corte, además al venir al vacío se deforman y al expandirlas (qué me llevó días) ya no regresan a su forma original, por lo que termine con algunas piezas sin usar y otras que use pero se nota qué están chuecas.

no cumple con las especificaciones, menciona que la densidad es 20 kg/m3 y no es cierto (tengo espuma de 17kg/m3 y esta mucho mas gruesa que esta), aparte que vienen mal cortados y todos disparejos. Es solo espuma de baja densidad ni para almohada sirven. Muy caro para lo que realmente es.
