Studiofoam® Wedges

Product Overview


1″ Studiofoam Wedges work most effectively on mid and high frequency sound waves and may be used to acoustically treat walls or, most commonly ceilings (especially if they aren’t parallel to the floor), even when the walls are treated with thicker acoustic Studiofoam. Perfect for those environments that demand good sound control, but where complete acoustic absorption isn’t required or desired.  1″ Studiofoam Wedges absorb as well as some competing 2″ products, so if your budget is a bit “thin” these are for you!

2″ Studiofoam Wedges are our most popular Studiofoam profile! Use them to treat small-to-medium-sized areas including vocal booths, control rooms and tracking studios. 2″ Acoustic Studiofoam is quite simply the workhorse of the industry and is your safest bet if you’re tuning your room yourself without the help of a professional acoustician.

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

4″ Studiofoam Wedges are recommended for rooms with pronounced low frequency problems or where sonic accuracy is mandatory and maximum acoustic absorption is required (e.g. voiceover or drum booths, forensic audio labs and mastering rooms). 4″ Studiofoam Wedges provide 3x the low-end control of 2″ and can effectively tame even the worst sonic anomalies. In some instances, using 4″ acoustic Studiofoam can lessen the need for significant dedicated bass trapping.
