CornerBlox Acoustic Studio Foam Bass Traps - 4 pcs - Charcoal

I stumbled onto these by accident. They are priced very nicely compared to similar products. In my opinion, they do the job well. I feel that my final mixes sound much more even. As far as listening to music, by dampening the bass, I can actually feel real bass now.This is a great starter product for me.

They work as expected. Not top of the line, but there is a noticeable difference in bass frequencies in my studio. It does assist when mixing. If you want something more budget friendly then you can do much worse than these.

I bought these from eBay. They don't do much - if anything at all. Save your money and possibly invest in DIY traps - foam doesn't do much and with these (they don't have much depth), you're not going to notice much of a difference.

These look good in my room corners but it's not like they're doing a lot.

These are very reasonably priced bass traps that perform the same function as their higher priced equivalents. I made the mistake of trying to put them up on my painted drywall with Liquid Nails (something which the company's website does say will not work - oops, should have read that first). I found this spray-on adhesive available on Amazon: http://www.amazon.com/gp/product/B0048KL4WQ/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 Worked like a charm. One tip, spray it on the wall rather than on the foam (the foam just absorbs the adhesive). I sprayed it on, waited about 30 seconds, pressed the foam in place for about 30 seconds, and voila! done.

I bought a few of these things for the bands home rehearsal space and they sucked up quite a bit of bass. Worth the purchase for sure and easy to use.

I use these for my home theater room and they have cleaned up the bass nicely. Don't expect a dramatic change, but enough to justify purchasing this product. I'm happy with the results.

These are sturdy Bass Traps. They provide a good level of control with the low end frequencies.
