Description

Micro90c is included in the Micio90t system only

The Micro90t home theater speaker system delivers exceptional performance from small speakers that virtually disappear

in your listening room. The front channels are handled by miniature monitors housing our most advanced drive unitsi

Boston-built, highepower, 31/2" (89mm) midrange drivers and our exclusive 1" (25mm) Lynnfield VRTM tweeter. The satellite

and center channel housings are made from dieecast aluminum. The great strength and rigidity of this material assure the

sound is not degraded by spurious resonances and cabinet vibrations.

A 757watt powered subwoofer With our 8" (200mm) Deep Channel Design (DCD'M) bass unit provides a solid foundation

for the system. The heavy-duty DCD subwoofer driver features a deeply grooved pole plate, developed using Finite

Element AnalySIs computer optimization, giving this driver tremendous excursion for clean, powerful bass. Drive power

comes from a Boston-designed highecurrent amplifierwith oversized transformer, for a subwoofer that translates demand-

ing program material into an exciting, thunderous experience.

Wallrmount brackets for the left and right satellites are included, and all units feature MagnaGuardQ magnetic shielding for

complete placement flexibility.
