Advanced Acoustics Bass Trap Corner Fill 12" x 12" x 12"


What's In The Box?


The Bass Trap Corner Fills are sold as single units.  The dimension of the corner fill is 305mm (12") by 305mm (12") by 305mm (12").  They are designed to be used in conjunction with any of our 12" wide bass traps to allow you to effectively treat the tri-corner - the corner where the two walls and the ceiling meet.  Treating this area will drastically improve the rooms frequency response.  It also gives a much neater finish when butting the bass traps up to the ceiling corner.  This area is wasted space so makes much sense to turn it into an area for additional absorption.  They are available in either Mid Grey or Dark Grey.


What Are The Benefits?


Sometimes the simplest method is the best method.  These bass traps are a simple design but don't confuse simple with useless.  Bass Traps are vital for any studio design and should be one of the top priorities of studio design.  Once effective bass control has been installed standing waves are minimised and low end build up is brought under control. 

Low end energy congregates in all corners of rooms so by placing effective bass traps in the corners you can reduce the detrimental effect this has.  When used in conjunction with our range of acoustic tiles the full scope of frequencies generated is taken care of.

The Bass Trap Corner Fill enables you easily treat the tri-corner by placing this cube in the corner where the two walls and ceiling meet.  Once installed you can fit any of our 12" wide bass traps up to each exposed side.  Using the Bass Trap Corner Fills gives a much neater finish compared to trying to cut bass traps at 450 angles.

Care is taken in optimising size, profile, foam cell structure and foam density to present a product that offers high visual and acoustic value.  Durability is high on our list of priorities too, we manufacture a foam that won't crumble and turn to dust and won't change colour as soon as you've mounted them in the corners. The bottom line is that the Original Bass Traps will assist both you and your room in working to it's full potential.
