KSW-12

Detailed Description

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. Available in 120 or 230 volt versions, 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.

KSW-12 Specifications

frequency response	26Hz-100Hz±3dB
power handling	*FTC Rated Power:* 105 watts continuous, 22-100Hz @ ≤ 1% THD **Dynamic Power:*** 440 watts @ ≤ 1% THD *Dynamic power indicates the actual power this amplifier will deliver to the woofer under normal operating conditions. While the FTC power rating indicates power available on a continuous, long-term basis, subwoofers do not rely on that type of power. Instead, the amplifier is called upon to deliver large, short-term peaks of power to be able to support the wide dynamics required by today's digital music and movie formats. In addition to the required FTC power rating, we've provided the dynamic power rating as a better indication of the product's true performance.
