The subwoofer we are going to talk about in this Klipsch R-120SW review well-worth your attention. It has a solid case and decent build. Let’s proceed into the body for more interesting facts!
The subwoofer has a Class D amplifier that develops a rated power of 200 W, which was made to order according to Klipsch specifications. This amplifier has low distortion and is precisely matched to the subwoofer speaker, thereby achieving high efficiency. Concerning other Klipsch R-120SW specs, the frequency range is 29 - 120 Hz.
The active subwoofer is designed for use in large rooms. It is made of selected MDF extra thick and complemented by internal ties. In general, this design has good acoustic inertness, that is, it does not color the sound even at high volume. The outer cover of the Klipsch R-120SW is made of high-quality vinyl film, which imitates natural wood very accurately. In addition, this coating has good mechanical strength. On the front panel of the Klipsch R-120SW is mounted a tweeter with a diameter of 12 inches. It is fixed with screws with large heads, which gives the subwoofer a brutal appearance. However, the Klipsch R-120SW can be made less visible in the interior by simply leaving a removable safety net in place. The subwoofer is equipped with a die cast graphite (IMG) diffuser and has high rigidity with low weight. To increase the sound output, the speaker is equipped with a lightweight voice coil and a powerful magnet. The antiresonant cast chassis serves as a reliable support for the bass player. The necessary acoustic load for the subwoofer is provided by the bass reflex, the outlet of which is located on the rear panel. On the rear panel of the Klipsch R-120SW there are controls for signal level, filter tune frequency, and an absolute phase switch. The subwoofer is equipped with damping supports, providing the necessary mechanical isolation from the floor surface.
The subwoofer has an automatic switch-on system when a signal appears at the input (linear or LFE connections are provided), as well as an LED indicator on the front panel.
