Providing mounting, enhanced performance and acoustic isolation in cavity wall and ceiling constructions.
Cavity wall backboxes are an easy to install mounting option in plasterboard cavity walls and ceilings (drywall) for Amina Invisible Loudspeakers . They create an acoustically tuned cavity behind the speaker, ensuring both consistent loudspeaker audio quality as well as minimising rearward airborne sound transmission.

For use when there is insufficient cavity space for an Amina cavity backbox (less than 75mm). Allows installation of Amina loudspeakers into plasterboard with a rear cavity depth of just 30mm – Please note, rear of loudspeaker should be covered using soft insulation material where mounting blocks are used to prevent ingress of debris over time.
Mounting block options for a range of plasterboard thickness are available, please state plasterboard thickness at time of order.
Shims available to allow alignment of speaker and backbox with any thickness plasterboard other than 12.5mm (1/2″) (or multi-layered build-up), ensuring that no more than 2mm plaster is applied to the front of a plaster-over loudspeaker.
These should be used where plasterboard thickness is greater than 12.5mm (1/2″), these will push the speaker forward.
To calculate correct loudspeaker shim requirement:
(Total plasterboard thickness) – 12.5mm = Shim thickness required
Double skin 12.5mm board: (2 x 12.5) – 12.5 = 12.5mm speaker shim
These should be used where plasterboard thickness is less than 12.5mm (1/2″), these will push the backbox and speaker assembly to the rear.
To calculate correct backbox shim requirement:
“12.5mm” – (total plasterboard thickness) = Shim thickness required
Single skin 10mm board: 12.5 – (10mm) = 2.5mm backbox shim
Please specify shim type, backbox size (CV345/300/200) and required shim thickness at time of order
High Impedance 100V/70V Line Transformers
Providing a great solution for high end commercial installations, all Amina Invisible Loudspeakers can be supplied with high-quality toroidally wound transformers for both 100V and 70V line systems.
With a choice of either fixed-power or multi-tapped transformers available for all Amina Loudspeakers, the ability to specify a flexible and high performing invisible system has never been easier. Multi-tap transformer allows for adjustment to specification up to the moment of installation. Multi-tap transformer shown fitted to iQ3 (iQ3+MT).
Multi-tap Transformer (MT)
100V tappings – 5W, 10W, 15W, 20W
70V tappings – 2.5W, 5W, 7.5W, 10W
Fixed-value Transformer (100/70T)
Options for fixed-value 20W, 40W or 60W transformers available if required.
Transformer value must be equal to or lower than the power rating of the loudspeaker it is being used with. Custom rated transformers may be available. Please contact your distributor if you have any special requirements.
Please state required amplifier voltage and power requirements at time of placing order. Please note that addition of transformers may increase lead time.
