Pyle Psi15 Sound Dampening Speaker Riser Foam For Studio Monitor, Subwoofer, Loud Speakers,(15 X 15 X 1.8 Inch)

I received two consecutive complaints from my new downstairs neighbor previously. However, after adjusting the bass even to 100, I didn't get any more complaints! If you've had a similar experience, this solution is definitely worth trying. It significantly reduced floor vibrations and rattling, and worked flawlessly with my Bose 900 setup, which includes a 700 bass module. The only downside is that it seems overpriced, and you might be able to create a DIY version if you have the necessary materials.

Great quality and very effective, now my Bose 700 Subwoofer is no longer vibrating or shaking my windows!

I recently tried out the Sound Dampening Speaker Riser Foam, and here’s what I found. The quality of the foam is impressive—it really does its job in reducing unwanted vibrations and improving sound clarity. Specifically, the low frequencies become noticeably tighter and bolder, which is a significant improvement for any audio setup. However, the high price point might not be justified. If you're handy or willing to do a little DIY, you can achieve similar results for much less. The materials and design are straightforward enough that you could easily replicate them yourself. Overall, while the foam does enhance sound quality, the cost might outweigh the benefits if you're looking to save some money. If you have the time and inclination, making your own risers could be a more economical option.

I use it for my KEF62 subwoofer and the size of perfect for this. It feels and looks nice. I'm still in the process of fine tuning bass and have almost cracked it...I think. There are times when the bass sound boomy...and I suspect I get some reflective sound off the floor and wall. Overall it's a great product.
