Description
The DX Pro is a high-performance, diffuse-field surround speaker with the frequency response and
power handling demanded by today’s finest home theater systems. Unlike conventional surround
speakers, however, the DX Pro mounts flush with the wall surface and virtually disappears in the
listening room.
The DX Pro duplicates the performance of the movie theater surround speaker array by aiming its
drivers away from the listening area. In contrast to direct radiating speakers, the DX Pro projects its
sound along the room’s walls, not at the listener. This creates a diffuse, lifelike ambient soundfield
for realistic surround effects.
Inside the DX Pro are two subenclosed 2
1
⁄2-inch (65mm) high-frequency drivers. One fires forward,
the other rearward. Frequencies below 900Hz are handled by our 5
1
⁄4-inch (135mm) driver with
butyl rubber surround. Gold-plated five-way binding posts allow quick connection to virtually any
speaker cable.
The front surface has a matte white finish, suitable for use in a variety of environments. For a
perfect custom finish, the speaker and grille may be painted using the supplied paint mask.
