Stopped corner slap immediately. Review: PUT THEM IN WATER & SQUEEZE! - Great Bass Traps they're pretty Solid thick and heavy. They come vacuumed sealed so out of the box they won't just expand by themselves. FOLLOW THE INSTRUCTIONS, put them in water (Like a bathtub as shown in pictures) squeeze them like a sponge and they'll soak up the water and expand and take form. Lastly throw them in the dryer for about 15 minutes or so or use a heat gun or hair dryer to get em nice and dry. Then use whatever adhesive you deem appropriate as they are pretty heavy I recommend using something strong like Gorilla if these are permanent to the room. Sadly they don't come with any means to stick them which is why I gave them 4 stars.

How can I restore their shape?** A: The foam may compress during shipping. Lightly soak the bass traps in water, squeeze out the excess, and let them air-dry completely to regain their original shape. **Q: The products have a strong smell when first opened. Are they safe?** A: Yes. The bass traps are made from formaldehyde-free polyurethane acoustic foam and are completely safe for indoor use. The initial odor may come from sealed packaging but will fade naturally after a day or two in a ventilated space. **Q: What’s the best way to mount them to the wall?** A: Use Foroomaco’s Mini Ear pads for clean, secure installation. They hold firmly without wall damage or residue. Make sure the surface is clean and dry before applying. **Q: Do I have to install them in the ceiling corners?** A: Bass traps are designed for three-surface corners where low frequencies naturally build up. Installing them on flat walls greatly reduces performance. Place them symmetrically in ceiling or floor corners for optimal sound balance. **Q: How can I tell if they’re working properly?** A: After installation, play music or a bass-heavy track in your room. You’ll notice that the boomy, muddy low-end becomes tighter and more controlled — a clear sign the traps are absorbing excess bass energy. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Bass traps. *by S***N on January 7, 2026* Items work perfectly.

All and all GREAT product highly recommended! 💯👍🏽 ### ⭐⭐⭐⭐ A Must have for treating your room reflections *by J***. on July 24, 2025* This is a great way to acoustically treat your theater or any space that needs help with echo and sound bouncing off different surfaces. They are made of a very dense foam material. These were the first acoustic treatments that I put up. I did notice a slight improvement as soon as I put them up. Again. These were the fist things I put up in my room. And they were the easiest. They fit in the corners nice and utilize every space available to add more treatments if necessary. I would have given 5 stars but I feel they need a few more pieces of the double sided tape. One did fall but I added a few more pieces of my double sided tape and they haven’t come down since. I love that they fit perfectly in the upper corners of the room. You really have to look to see mine. The price was definitely worth it. It is a great quality product and super easy to install. ## Frequently Bought Together - Foroomaco 4 Pack Bass Traps for Ceiling Corner 16.5" Triangle 12" Depth Triangular Pyramid Acoustic Foam Bass Trap Sound Proofing for Home Studio Booth Low to High Frequency Sound Absorption Foam - Focusound 300 Pack Yellow Point Double-Sided Adhesive Dots for Acoustic Soundproofing Foam Panels - Sonic Acoustics 12 Pack Acoustic Foam Panels 7" X 7" X 12" Sound Absorbing Panel, Bass Trap Studio Foam, Corner Block Finish, Sound Panels Soundproof Sound Insulation Absorbing --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/449214766-4-pack-bass-traps-for-ceiling-corner-16-5-triangle](https://www.desertcart.co.uk/products/449214766-4-pack-bass-traps-for-ceiling-corner-16-5-triangle) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-17*
