Unpacking the Speakers
Use care when unpacking the speaker. Remember to save all packing materials until you
are certain that the speaker has suffered no damage in shipment. If you find such damage,
either visible or internal, contact your dealer immediately.
If you can do so, save the carton, packing pieces, and plastic bags that came with your
speakers. They will be useful if you move or have to ship your loudspeaker for any reason.
Speaker Description
The IW-155SR is a thin-bezel in-wall surround speaker that delivers spacious, enveloping
surround effects for top grade home theater systems. It features an innovative dual-concen-
tric driver design capable of filling the listening area with either three-dimensional ambient
sound or object-based positional audio essential for lifelike theater sound.
The IW-155SR consists of dual 5.25” woofers and dual concentric 1” silk dome tweeters
mounted in a resonant-free MDF baffle. The speaker is a switchable dipole/bipole design;
that is, the two sets of drivers can either be set for out-of-phase (dipole) operation, ideal for
a diffuse, non-localizable sound, or set for in-phase (bipole) operation, for a more direct,
localizable effect, perfectly suited for object-based audio formats such as Dolby Atmos.
Either mode will fill a large home listening area with dramatic surround effects. The thin
bezel grille is magnetically attached to the frame and can be easily painted to match virtu-
ally any décor.
