THEM HIGH-PERFORMANCE SUBWOOFERS AT AFFORDABLE PRICES.
SPUN COPPER FRONT-FIRING CERAMETALLIC WOOFERS
Cerametallic™ woofers are exceptionally light and extremely rigid, providing
remarkable low frequency response with minimal cone breakup and distortion
for higher, cleaner output using less amplifier power.
HIGH EFFICIENCY CLASS D AMPLIFIER
The built-in, high efficiency amplifier features an analog preamp design, which
maintains the original signal path for cleaner, true-to-source reproduction. The
Class D output stage ensures maximum efficiency for maximum output, detail,
and low frequency power.
FRONT-FIRING SLOT PORT WITH EXCLUSIVE INTERNAL FLARE
TECHNOLOGY
Proprietary internal geometry that minimizes port noise for clean undistorted low
frequencies. The front-firing design allows for placement flexibility.

The Klipsch WA-2 Wireless Subwoofer Kit (sold separately) allows high
resolution wireless connectivity for easy placement anywhere in your room
and optimizes output and low frequency response. Connect up to four
WA-2 wireless kits to compatible Klipsch subwoofers in a single room for a
completely wireless connection.
FLEXIBLE CONTROLS
Low Pass Crossover and Variable Phase control allows you to tune the
subwoofer to your Klipsch speakers and to your room, establishing the ideal
level of bass. Line Level / LFE RCA inputs ensure compatibility with home
theater receivers.

Both the RCA and wireless inputs can be utilized, giving you the ability to use a
single subwoofer with multiple system in the same room. For example, you can use
the wireless input for your home theater set up and the RCA input for your 2-channel
system, without needing to switch inputs when changing between systems.
