I’ve had this wonderful subwoofer for a number of years and it delivers a whopping sound! I’ve seen it for sale for $300+ so at this price – you can’t miss! Sorry, there are NO wires or cables (Easy enough to pick up).
Information I’ve picked up on the web:
The Synergy Series KSW-12 subwoofer packs a powerful punch. It uses high-quality materials and the most reliable components to deliver deep, driving bass that intimidates competing designs. This high performance subwoofer perfectly anchors a home theater or two-channel music system. The KSW-12 couples a 12-inch driver to the floor for optimal performance. Its high-output, down-firing design “grips” the air and fills a room with low frequency energy that’s heard and felt with undetectable distortion. The built-in discrete MOSFET amplifier and 12-inch fiber-composite woofer are as efficient as they are reliable. This subwoofer accepts LFE, line-level and speaker level inputs. The classic jet ash vinyl veneer finish creates a deceivingly subtle exterior for its room-rocking capabilities.
A bit repetitive, but an Amazon.com review:
REVIEW: Complete a powerful home theater system with the deep, driving bass of the Klipsch KSW-12 powered subwoofer—perfect for combing with high-performance Klipsch Synergy Series surround sound configurations. It couples a 12-inch driver to the floor for optimal performance. This subwoofer’s high-output, down-firing design “grips” the air and fills a room with low frequency energy that’s heard and felt with undetectable distortion. The built-in discrete MOSFET amplifier and 12-inch fiber-composite woofer are as efficient as they are reliable. It provides 105 watts of FTC-rated continuous power, and it has a dynamic power rating of 440 watts. (Dynamic power indicates the actual power this amplifier will deliver to the woofer under normal operating conditions.)
The woofer is composed of a Santoprene rubber surround with a fiber composite cone which enables Klipsch subwoofers to deliver on their promise of extended bass response and maximum reliability. This subwoofer accepts LFE, line-level, and speaker level inputs, making it easy to add to the Quintet Microsystem, the Synergy System 6, or any other Klipsch inspired arrangement. The KSW-12’s jet ash veneer vinyl finish creates a deceivingly subtle exterior for its earthshaking sound capabilities.
