Features

These bass traps work in rooms of any size. Low frequency waves are long and difficult to stop, but corner bass absorbers solve the bass problems that collect in the corners of rooms. The eight pack contains an absorber for each corner of a four-sided room, though smaller packs are also available. For rooms with severe bass issues and multiple walls, we suggest absorbers in every corner. They work great as general sound absorbers and in conjunction with other products.

Voice actors need Foam Factory

Stop buying Auralex and the cheap Amazon junk and get top grade foam and fast shipping from these guys. I’ve built out 2 studios with their products and they are the best!

Short version: Foam By Mail nails the price to performance ratio with their acoustic foam products. I had Auralex in my studio already and these perform just as well for a MUCH better price. Skip Amazon knock offs, skip Auralex, order here. Long Version: I am a semi-serious sound engineer/producer who has put roughly $15k into converting my one car garage into a double walled home studio. I record LOUD rock, punk, hardcore, and metal musicians. The majority of my acoustic treatment are the higher end dense fiberglass panels. However those require wood frames (heavy) and there are somethings that those are just too awkward to work for (metal doors, vaulted ceiling corners, tight squeezes under desks, etc.) No secret that foam doesn't perform as high as rigid insulation panels, BUT if you try to buy "big brand acoustic foam" (you know who) it costs just as much as doing top of the line panels. Alternatively, if you try to buy cheap stuff on Amazon, you get NO PERFORMANCE. Foam by Mail nails the price point and performance ratio beating out both big name foam and cheap knock off foam. I'll be doing another order soon to finish up some of the harder to reach untreated corners. TIP: If you think you may want to reposition foam, or you live in a rental and can't glue to walls, glue it to thin plastic sheets and then use command strips to put it on the wall. Works great!
Quality product

The acoustic foam products are an excellent bargain, they are a fraction of the cost of a lot of the mainstream big name products out there. And from what I hear I see no reason at all to spend a dime more on acoustic treatments. Nice work Foam Factory
WOW!

Superb Quality

I've had many corner bass traps. These are as good as any and far less expensive. Especially if you're trying to outfit a studio or control room on a budget, these fine folks are aces! Try them, you'll love the experience and the products!
