Сабвуферы — Klipsch R-101SW

The R-101SW is the 10-inch powered subwoofer in the 2021 update of the Klipsch Reference range and the successor to the R-100SW, which Klipsch now labels as the older model. It shares its owner's manual with the larger 12-inch R-121SW. The main changes against the earlier generation are a new woofer cone material, a deeper cabinet and new internal bracing. The only listed finish is black textured wood grain vinyl over MDF.

Key specs that matter

The front-firing 10-inch high-excursion woofer uses a spun-copper Thermoformed Crystalline Polymer (TCP) cone. Its all-digital amplifier is rated at 150 W continuous with 300 W available as a peak figure. Frequency range is given as 29.5 Hz to 120 Hz, and maximum acoustic output reaches 115 dB. Bass loading is by reflex, with the port opening on the back. Dimensions are 370 mm high, 356 mm wide and 500 mm deep, and one unit weighs 13.9 kg.

Engineering and use context

Klipsch describes the TCP woofer as light, stiff and tightly packed, which keeps breakup and distortion low without the material degrading over time. Against the R-100SW, which is rated down to 32 Hz and 112 dB, the newer model reaches lower and plays louder with an unchanged amplifier, helped by its deeper cabinet. The walls are 19 mm MDF, reinforced with a newly designed bracing layout intended to cut cabinet vibration. User controls cover level, a variable low-pass filter reaching up to 160 Hz, and phase that flips between 0 and 180 degrees. An Off, Auto and On selector lets the amplifier start on signal detection and drop to standby after 15 to 20 minutes without input, or stay permanently on. The power LED sits on the front and turns green when the amplifier is active with a signal present. A low-profile grille covers the driver.

Pairing

Connection is line level only, through a pair of RCA inputs labelled L/LFE and R. One cable running from a surround receiver's LFE jack goes to L/LFE, while a stereo system without a dedicated sub output can feed both jacks from its left and right pre-outs. With the receiver doing the crossover, the sub's filter is left at maximum. If the sub does the filtering, Klipsch suggests 50 Hz to 90 Hz with floorstanding mains and 90 Hz to 150 Hz with small bookshelf or satellite speakers, and the phase switch is set to whichever position gives more output at the seat.

Alternatives

The Klipsch R-121SW is the 12-inch TCP model of the same Reference generation, rated 200 W continuous with a 28 Hz lower limit.
