The Reference R-115SW subwoofer is the perfect combination of power, sophisticated and heart-pounding bass. Packing a serious punch, the R-115SW will not only wake your neighbors, it'll piss them off. The way only Klipsch can.
It's worth noting that [the dual R-115SW subwoofers] did offer enough headroom to handle everything I threw at them. They are big subs with genuine room-shaking output that drops right into the infrasonic realm.Mark Henninger | AVS Forum
The R-115SW, R-112SW and R-110SW boast spun-copper Cerametallic woofers that are exceptionally light yet extremely rigid – providing remarkably low-frequency response with minimal cone breakup and distortion. Basically more boom, less effort.
Low pass crossover and phase control allows you to blend the subwoofer’s low-frequency tones with other Klipsch speakers as well as establish the ideal level of bass. Get a smooth, even dispersion of bass that suits your room size and layout.
Available in three different sizes, these Reference Subwoofers are ready to rock the room, whatever size it may be.
Tightness and punch are this sub's thing...This punchy character makes the R-115SW stand out a bit from most of the 15-inch subs I've tried.Brent Butterworth | Home Theater Review
