The on-wall version of the ID1, the ID1.W combines dual 10 inch subwoofers with a 3-Way loudspeaker. A home theater processor may be used to provide the subwoofer crossover and to operate the ID1.W as part of a surround system or as a two-channel stereo system. The ID1.W features wooden cabinetry in standard or custom finishes. Face plate is removable so the aluminum back plate can mount directly to wall. S4X circuitry compensates for on-wall baffle effects. The ultimate in audio perfection, the ID1 series includes 3-Way and 4-Way speakers in tower, in-wall, and on-wall designs. Built to function as left and right mains, theses speakers pump rich sound from deep bass to crystal clear highs.
