TroyStudio Periodic Bass Traps - 4 X 4 X 12 Inches 12 Pcs Dense Studio Acoustic Foam, Acoustic Bass Corner Reduce Reverb Echo, Acoustical Treatment Sound Foams for Home, Office Recording Studio

Great quality. They work well.

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

I didn’t expect acoustic panels to make this much of a difference—but these VEVOR panels completely transformed my space. First off, the size is a huge win. Each panel is large (48 x 24 inches), so you actually cover meaningful wall area without needing dozens of pieces. Installation felt efficient instead of tedious, and the clean black finish gives the room a professional studio look right away. The egg-crate design isn’t just for looks—it genuinely works. Before installing these, my room had a noticeable echo and muddy sound, especially when recording vocals and mixing. After putting them up, the difference was immediate: tighter sound, less reverb, and way more clarity. It feels controlled, like a proper studio environment instead of a regular room. What really impressed me is the balance they strike. They absorb sound effectively without making the room feel “dead” or unnatural. Whether you’re recording, producing, or just trying to improve overall acoustics for listening, these panels hit that sweet spot. Build quality is solid too. The foam is thick (2 inches) and holds its shape well—no flimsy or cheap feel. They also arrived in good condition and expanded properly after unpacking. Overall, if you’re serious about improving your audio setup—whether it’s for music, streaming, or content creation—these panels are a no-brainer. Great performance, clean aesthetic, and excellent value for the size. Highly recommend.

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.

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.
