ABSORPTION CHARACTERISTICS:*
Sound absorption coefcient data
The London Bass Trap™ kit consists of two 24” x 48” panels that effectively
absorb sound energy from 75Hz and up. Designed to be corner mounted
at ear-height, or stacked oor to ceiling, the kit provides substantial surface
area for broadband absorption with effective coverage down into the low
bass region.
The London Bass Trap kit is constructed from fabric wrapped, high-
density glass wool Broadway panels. When installed in the room corner,
a 17” deep air space is formed behind the panel. This air space provides
signicant absorption in the problematic low-mid (100Hz – 200Hz) region
while seamlessly integrating with other Broadway panel installations.
Mounting is achieved using the included Primacoustic Corner Impalers.
The Primacoustic London Bass Trap kit is available in black, beige or grey
fabric or in Absolute White™ paintable nish. Sold in pairs.

PANELS
Primacoustic corner impalers make
it easy to mount the 24” x 48”
Broadband panels across room
corners to form effective bass traps.
Like the surface impaling clips, the
corner impalers feature sharp tips
that penetrate the panel and hold it
securely in place.
