🔊 12” IMG Woofer – Lightweight, Durable, and Powerful

At the heart of the R-120SW is a 12-inch front-firing IMG (Injection Molded Graphite) woofer, known for being both exceptionally lightweight and extremely rigid. This combination allows for high efficiency and low distortion, producing dynamic bass that’s clean and fast, even during intense low-frequency moments like action scenes or heavy bass drops.

The woofer is finished in Klipsch’s iconic copper color, giving it a striking appearance that complements the Reference Series’ signature look.

⚡ 200W RMS Digital Amplifier – Clean Power On Demand

The subwoofer is powered by a 200-watt RMS amplifier with a peak capability of 400 watts, delivering more than enough punch to fill medium and large rooms. The all-digital design ensures high efficiency, accurate signal reproduction, and minimal distortion, so you get bass that’s not just loud — it’s precise.

Whether you’re watching movies or listening to music, the amplifier’s tuning ensures a tight, impactful response across the subwoofer’s entire frequency range.

🌀 Front-Firing Port – Distortion-Free, Deep Bass Anywhere

The R-120SW features a front-firing bass reflex port, which is designed to maximize airflow while minimizing port noise. This allows the subwoofer to produce clean, deep bass at higher volumes, without the “chuffing” or turbulence that can plague lesser models.

Because the port is front-facing, the sub can be placed closer to walls or inside media cabinets without compromising performance — offering flexible integration with your room layout.

🎛️ Control Panel – Dial in Your Ideal Sound

On the rear panel of the R-120SW, you’ll find a simple yet effective set of controls:

• Low Pass Crossover (40Hz – 120Hz): Lets you adjust the sub’s upper frequency limit to perfectly match your main speakers.

• Phase Switch (0°/180°): Ensures the sub’s output is in sync with the rest of your system, avoiding unwanted bass cancellation.

These controls help you fine-tune your sound for smooth integration with bookshelf speakers, floorstanders, or soundbars.

🔌 Versatile Input Options – Easy to Connect to Any System

The R-120SW is equipped with:

• Line-Level RCA Inputs: Connect to stereo amplifiers, preamps, or processors.

• LFE Input: Directly hook into your home theater receiver’s subwoofer output, bypassing the internal crossover for optimal AV calibration.

This makes the R-120SW compatible with virtually any audio setup, from 2-channel stereo to 5.1 and beyond.

🧱 Sleek Cabinet – Designed to Perform and Blend

The cabinet is built from MDF (Medium Density Fiberboard), which offers excellent acoustic dampening and rigidity. It’s finished in a brushed black polymer veneer that blends seamlessly with modern and classic decor alike.

At the front, the removable magnetic grille gives you the freedom to display the signature copper woofer or opt for a clean, minimal appearance. Rubber feet ensure it stays stable and vibration-free on hard floors.
