The BackboxCV345 is an easy to install mounting option in plasterboard cavity walls (drywall) for Amina Invisible Loudspeakers with the dimensions 345mm x 450mm (Edge5i, Edge7i, Mobius5i, Mobius7i, MobiusDual). The CV345 creates an acoustically tuned and consistent cavity behind the speaker, ensuring both consistent loudspeaker audio quality as well as minimising rearward airborne sound transmission.
Designed to be retrofitted into a 12.5mm plasterboard wall or ceiling, the Backbox CV345 provides a consistent mounting platform to achieve correct loudspeaker alignment. The backbox should only make contact with the rear of the plasterboard
and not touch the stud framework, this is to minimise the likelihood of mechanical noise transmission from the speaker into the structure of the building.
Sound Absorption Characteristics:
When used with an Amina Invisible Loudspeaker, the BackboxCV345 offers an amount of airborne noise transmission reduction. With an average attenuation of 26dB between 150Hz-20KHz, the BackboxCV345 is the easiest way of mechanically fixing the loudspeaker to the plasterboard whilst also limiting rearward airborne transmission and helping to achieve consistent loudspeaker performance. It is recommended that additional steps are taken to reduce rearward transmission if speakers are to be located in partition walls, or will back onto an adjacent occupied room (bedrooms above living spaces etc).
