The IWS-10 subwoofer driver employs a rigid, flat 10” surface of 10 mm (3/8") RDT material derived from Monitor audio’s acclaimed ‘Platinum’ series of high-end speakers. A large vented pole helps to move air quickly, reducing power compression and increasing heat dissipation. It features Monitor Audio’s patented Tri-Grip clamping system and paintable trim-less grille and frame edge.
