Plano is a bass absorber with a plane surface of wood, aluminium or white varnished steel. The steel version can even be delivered in any color on demand.
Aluminium silver
Steel white
Wood nature
With a medium weight aluminium front plate Plano shows even absorbing properties in the bass.
The varnished steel plate being heavier, Plano works still better in the bass. Besides the descreet white finish any special color can be delivered.
The wooden look gives a warmer appearance. The plate being lighter than the metal variants, the dampening effect in the bass is a little smaller.
