Twice as absorbent as 2" Studiofoam at 125Hz, Auralex 3" Studiofoam Wedges can even do many of the same things 4" Studiofoam can do (especially when used with Auralex LENRD or Venus Bass Traps) and can provide a well-controlled, more accurate sound in any size room.

Recommended for rooms with higher sound pressure levels or more low frequencies such as drum or voiceover booths. Rooms often have more low-end problems than some folks acknowledge, so if you step up from 2" thick Studiofoam to 3" thick, you will benefit from the extra low-end absorption 3" Studiofoam Wedges offer.
