Installation Guide

Our aim was to design a high performance bass trap that would outperform bass traps costing many times the price. The result is the LF70 – BEAR corner bass trap, featuring a unique reflective diffuser insert which significantly increases low frequency absorption.

The LF70 insert greatly improves absorption between 60 and 160Hz, compared to a traditional acoustic foam bass trap.
Test results (see below ) Without the insert roll off rapidly begins below 160hz. With the insert installed absorption co-efficients are significantly improved.
For example at 80Hz:  .38 (38% absorption) with insert removed vs .7 (70% absorption ) with insert installed.
 
At higher frequencies the insert reflects to allow a room to retain a natural sense of space. They are matched perfectly with the HA600/75 wall panel.

Research and Development

From our research and development of the HA600/75 hybrid panel, we thought perhaps a similar approach could be applied to a corner bass trap. Acoustic laboratory testing revealed that by incorporating a reflective insert of the correct size and mass the low frequency absorption of the bass trap can be significantly improved.  The BEAR series bass traps also provide a unique level of flexibility.  If more high frequency absorption is desired, the diffuser insert can be easily removed.  And of course we couldn’t resist the BEAR acronym – makes it a BEAR trap!

Corner Bass Trap

Installation of the LF70 bass trap is incredibly easy utilising the “Staple T” channel (see below) unique to Sound Acoustic products. The bass trap can be installed with either staple gun, removable hooks (such as 3M Command hooks) or with water based builders adhesive.

The LF70 comes standard with a raw timber flexible plywood insert that can be painted, stained or varnished without impacting the acoustic performance of the trap.

Dimensions: 1000mm high 520mm across front face

Performance: Effective absorption down to 70hz

The LF70 is also the ideal partner for the HA600-75 acoustic, working together to provide a balanced professional acoustic treatment.
