This bookshelf loudspeaker features 3.5" FCCM woofers and 1" EWB tweeter. Deep Channel® Design (DCD) for more bass from less amplifier power. Meticulously designed and solidly crafted, the most discriminating enthusiasts will revel in the small details. Each Reflection Series speaker comes cleverly appointed with magnetic grilles and stylish contours for an uncluttered visual appeal. In a two-channel music system, as surrounds in a multichannel home theater, or as front speakers with the RS 223, this versatile bookshelf speaker is compact enough to sit comfortably on virtually any shelf, stand or tabletop.
