Realtraps Minitrap 2’x4′ High Frequency

PRODUCT OVERVIEW

The RealTraps product line is based on real membrane bass traps that also absorb mid and high frequencies. This makes them a total solution for recording studios, listening rooms, home theaters, auditoriums – anywhere economical yet very high performance acoustic treatment is required.

All of our products are small and lightweight, so they’re easy to handle and can be shipped economically. They mount easily with one screw or hook – just like a picture – without glue or permanent wall damage. They can also be mounted vertically or horizontally as space permits, or high up on a wall where they’re out of the way. And since RealTraps products are made with rigid fiberglass and metal instead of foam, they’re non-flammable and can be installed with confidence in public venues.

“MiniTraps offer an ideal balance of high performance at an attractive price.”

MiniTraps are 2 by 4 feet, 3-1/4 inches thick, and weigh only 16 pounds. Despite their small size these are real performers that have exceptional specs, especially at low frequencies. MiniTraps perform far better than anything else in their price range, and better than products that cost a lot more too!

When mounted in corners MiniTraps absorb very well to below 80 Hz, and are still effective (0.30) to as low as 40 Hz. Although MiniTraps cost more per unit than foam they are far more effective, absorbing nearly six times more than typical corner foam below 125 Hz. So treating an entire room with MiniTraps not only gives much better results than foam and with fewer pieces to install, the cost is similar or even less.

One reason MiniTraps are so much more effective than other treatment is the air gap behind the panels. When mounted on a wall with a spacer, sound gets behind a MiniTrap so its rear surface can also absorb. This air gap increases absorption as much as fifty percent, and also extends absorption to lower frequencies when compared with flat wall mounting. When placed straddling a corner the absorption is even greater, especially at low frequencies. Not only because sound waves can get to the back of the trap, but also because the air gap is so large there.

We also offer a High Frequency model that absorbs more at mid and high frequencies. Where standard MiniTraps are intentionally semi-reflective at higher frequencies, the HF type trades slightly less low frequency performance for maximum absorption above 250 Hz. This is useful for reducing echoes and overall ambience, or to treat first reflection points in a listening room.

Although MiniTraps cost more per unit than foam treatment, they are far more effective, even when compared using foam’s inflated specs as explained in Measuring Absorption, also on the Articles page. And since the front surface of a MiniTrap is semi-reflective at mid and high frequencies, you can install enough of them to truly solve low frequency problems, but without making the room too dead as happens with foam or plain fiberglass.
