Perfect for use in rooms where a more architectural look is desired such as offices, churches, home theaters or recording studios.

The differing height protrusions on the 4" Studiofoam Metro-24 panel serve to spread sonic energy out in the time domain, as well as each absorbing a slightly different slice of the frequency spectrum. Since it takes slightly different amounts of time for sound waves to travel through the different sections of the panel, strike the mounting surface and travel back through the panel into the room, the wave-fronts are in effect softened rather than just being absorbed.

A 4" Studiofoam Metro-24 treated room will retain a bit more "feel" than a room that's treated with a stronger acoustic absorber like 3" or 4" Studiofoam Wedges or Pyramids. A well-controlled, natural-sounding acoustic space will result when coupled with a judicious amount of MetroFusors.

The panel displays slightly more absorption than a 2" Studiofoam Metro-24.

Linear and moderate mid/high absorption

Designed for minimal installation seaming. Panels can be installed side by side with virtually no vertical seams showing

Related Questions and Answers

Q: 1. How do these attach to wall?

A: Greetings Kelley, There are a few options for adhering them to the wall. FoamTak Spray adhesive and TubeTak Pro adhesive applied with a caulk gun. These options are permanent. For a more temporary application you could use the adhesives to glue the Wedgies to a cardboard or poster board as a backing. Then hang them as a group on picture frame hooks by carefully piercing the backing. They can also be hung with finishing nails tacked carefully through the Studiofoam at an angle without going all the way through. As mentioned by a community member velcro strips can be used but sometimes fail in sticking to the Studiofoam. Best regards, Kevin

Q: 2. Are these panels fire rated? What is the rating?

A: The Auralex Studio Starter Kit has a fire rating of UL 94 HF-1.

Q: 3. Are these actual Auralex brand panels? They're about a 1/4 of the price at other retailers.

A: There are no markings on the panels themselves, but I trust B&H. I have used them to wrap my multimedia room and they work great. I did not buy the Auralex adhesive, and used a spray can of 3M Super 77 (from Home Depot) and it works great.

A: Certainly. The code is for the download may only be used once.

Q: 5. Where are these placed to start improving your sound system?

A: The Auralex LENRD Bass Traps are intended for placement in room corners and wall/ceiling junctures.

Q: 6. If I have four talent booths I would like these in will one pack of these help for each booth? Are these something I can put a couple on a wall to help with the sound or does the whole wall need to be covered?

A: The Auralex Studiofoam Wedgies (Charcoal Gray, 24-Pack) provide 24 square feet of acoustic treatment coverage per pack. The amount of treatment required in each use case depends on the space and how reflective it is in general. Depending on the size of the booths in question, one pack should usually be enough for each, or could perhaps even be split between two booths.

Q: 7. Do these panels come in other colours? Blue, e.g.

A: We currently offer this 24 pack of 2" X 12" X 12" in gray alone. We do offer other color options like purple (B&H# AUSF222PU) and burgundy (B&H# AUSF222B ) in packs of 12 measuring 2" X 24" X 24" per wedge.

Q: 8. How do you mount these?
