My project has me doing floor and ceiling runs in a 12'x18' room. Trying to piece these together in a longer run has been maddening and has added so much time for installation. Sometimes you'll get lucky and find some with the same color, but of course none of them match in size. There is a +/- variance of up to .25". That means the blocks will actually be anywhere from 2.75" or 3.25" on each face. Most of them are not even squares, but rectangles. They are an installation nightmare if you want any type of accuracy end to end.In the end they do what I need them to do, and in conjunction with the 12x12x2 wall tiles sold by the same company my new recording space is sounding fantastic.I would never buy these corner blocks again. ### ⭐⭐⭐⭐⭐ Pleasantly Surprised *by T***H on Reviewed in the United States πŸ‡ΊπŸ‡Έ on April 20, 2015* I wasn't sure wether or not this would be a quality product or not due to the price. I was pleasantly surprised to see that it was just as dense as the name brand studio foam I have. A couple of pointers when installing: double sided tape doesn't stick very well to it and some of the cuts vary slightly in width. So comparing the pieces before hanging them is a good idea. All in all, though, this is a great product. ### ⭐⭐⭐⭐⭐ work well! *by J***C on Reviewed in the United States πŸ‡ΊπŸ‡Έ on October 8, 2015* These serve their purpose very well. If you use some 3m spray contact cement, you can bond multiples together and make your own wedges or whatever with a razor. I made corner trap baffles with these and they substantially calmed my room's metallic sounding slap down. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.id/products/10565724-16-pack-acoustic-foam-corner-blocks-3-x-3-x](https://www.desertcart.id/products/10565724-16-pack-acoustic-foam-corner-blocks-3-x-3-x) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-05-10*
