Ghost Big Block - 120cm x 60cm, Wall Mount Only
The ‘Big-Block’ is a larger version of
the Med-Block, meant for wall mounting only. It’s rectangular
shape means it can be mounted either vertically or horizontally
depending on the area that needs to be treated. In a basic room
kit it is designed to be mounted horizontally on the rear wall behind
the speakers, to absorb any unwanted reflections immediately in
front of the listening position in your studio/programming room.
It is constructed with high density (100kg per cubic metre) Glass
Fibre and layers of Aluminium foil, and finished in a brushed Aluminium
frame with fire retardant polyester fabric, and has similarly, and
highly effective, full frequency absorption to the ‘Block’.
Test data from the Institute of Acoustics (at Tongji University,
China’s leading authority on acoustic studies) shows highly
effective (30-44%) removal of all audible frequencies down to 200Hz,
and around 20% even down to 125 Hz with standard wall mounting.
Many competitor brands do not publish % absorption figures, mask/confuse
true figures with data that is not easily interpreted, or quote
figures which are boosted by mounting units with air gaps which
will ‘artificially enhance’ the performance of any acoustic
tile or trap. As an off the shelf product, we believe Ghost Traps
are the most effective, affordable product on the market today.
The ‘Big-Block’ uses Ghost’s proprietary ‘Easy
Mount’ system for wall fixing. Each trap ships with a lightweight
metal frame which screws into the wall. Traps can then be easily
hung and removed (after initial installation), in just seconds!
This allows the user to alter the room’s acoustic characteristics
depending on the job in hand… so, if you need a more ‘live’
sound to your room for recording drums for example, you can quickly
remove panels to customise the acoustics, and easily replace them
for listening while mixing and mastering.
