NIRO 620 SYSTEM SILVER
Each of the 2.5-inch, full range drivers in this unit is housed
individually within the speaker box, constructed of high grade wood to
reduce cabinet resonance. Coarse grill fabric is used for maximum sound
penetration; range response is 30Hz to 20kHz. The wide shape of the
cabinet has been engineered for maximum effectiveness in spreading the
surround soundstage. Accurate sound localization is delivered with any
source, either with 5.1 surround information, or with music in
2-channel stereo.
