Klipsch R-115SW vs Klipsch R-120SW

It is hard to determine who actually deserves your attention: Klipsch R-115SW vs R-120SW. As far as both Klipsch units have a built-in digital amplifier that provides ample power with high performance and fidelity. The low crossover and phase control allows you to clearly synchronize the low-frequency sound of the subwoofer with the sound of the remaining speakers of the Klipsch system, as well as to establish the optimal level of bass.

Features & Performance

Klipsch Reference R-115SW is a powerful active subwoofer, made in the type of “bass reflex” with a front speaker. The rectangular phase inverter port is located on the front panel.

The R-115SW is equipped with a 381 mm-long low-frequency diffuser made of a polymer material with the addition of Cerametallic copper and a 400-watt Class D power amplifier. It can become a reliable partner for Reference Premiere speakers. Compare this sound with other models - you’ll be amazed.

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 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. The subwoofer is equipped with damping supports, providing the necessary mechanical isolation from the floor surface.

Design

Comparing Klipsch R-115SW vs Klipsch R-120SW design, I should say that in addition to first-class technical characteristics, the Klipsch Reference R-115SW subwoofer has a strict exterior finish with Brushed Black textured vinyl, and its deepest basses combine with the relatively compact dimensions of the case.

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 versus other devices on the market, the speakers are equipped with a lightweight voice coil and a powerful magnet. The antiresonant cast chassis serves as 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.

Klipsch R-115SW pros & cons

Pros:

Full digital amplifier.
LF cutoff frequency and phase adjustment.
Wireless connectivity with optional Klipsch WA-2 Kit (sold separately).

Cons:

Of the shortcomings, I can only highlight that the case can be very badly spoiled - this upsets, as for an aggregate of this class. But as such, a good thing.
