With five identical satellites, a matching horizontal center speaker and a floor-shaking 150-watt subwoofer, the SCS160SI completes your 5.1 or 6.1 surround sound system. The five satellites are true 2-way speakers with advanced titanium-laminate-dome tweeters and dual drivers for more sound power an realism. The center channel speaker is identical to the satellites for seamless pans, wiht two midranges for extra power and clarity in the dialogue channel, but is configured for horizontal placement on top of many televisions. The satellite and center speakers are all video-shielded for placement near a television. The room-shaking 150-watt powered subwoofer delivers the excitement of thunderous, penetrating bass. All cables and satellite wall-mount brackets are included.
