🔊 12” Cerametallic™ Woofer – Lightweight and Rigid

At the core of the R-112SW is Klipsch’s premium 12-inch Cerametallic™ woofer. This rigid yet ultra-light material is engineered for minimal distortion and maximum efficiency. It maintains shape under high-pressure movement, meaning it can move more air without flexing — a must-have for delivering fast, accurate, and ultra-deep bass.

Not only is it high-performing, but the copper-spun finish makes it visually stunning — a bold design statement that looks as good as it sounds, especially when you remove the magnetic grille.

⚡ 300W All-Digital Amplifier for Power and Precision

The R-112SW is driven by a high-performance all-digital amplifier that produces 300 watts continuous (RMS) and peaks at 600 watts. This amp is perfectly matched to the woofer, giving you tight bass control, lightning-fast response, and power on demand during explosions, bass drops, or fast cinematic transitions.

Because it’s digital, the amp also runs cool and efficiently — which means you get high output without excess heat or energy loss.

🌀 Front Slot Port – Flexible Placement, Reduced Noise

Instead of a traditional round port, the R-112SW uses a front-firing wide slot port. This flared design reduces port turbulence, allowing air to move smoothly and efficiently. The result is cleaner, distortion-free bass even at high volume levels.

The front placement also means you can position the sub closer to walls or furniture, offering more flexibility for room layout and maximizing bass impact where it matters most.

🎛️ Crossover and Phase Control – Perfect System Integration

Getting the best performance from a subwoofer means aligning it with the rest of your system — and the R-112SW gives you the tools to do just that:

• Adjustable Low Pass Crossover (40Hz – 120Hz): Tailor the sub’s frequency range to blend with your main speakers.

• Phase Switch (0° / 180°): Aligns the subwoofer’s timing with your other speakers to avoid bass cancellation or phasing issues.

Combined with your receiver’s settings (like LFE crossover), these controls help ensure the subwoofer integrates seamlessly into any 2.1, 5.1, or 7.1 system.

🔌 Easy Connectivity for Any Setup

The R-112SW comes equipped with:

• LFE Input (Low-Frequency Effects): Direct connection to your home theater receiver’s subwoofer output.

• Line-Level RCA Inputs: For use with stereo amplifiers or older audio equipment.

This versatility makes the R-112SW suitable for both modern AV receivers and classic hi-fi systems, and lets you expand your system without needing a complicated setup.

🧱 Premium Build and Elegant Finish

Encased in a reinforced MDF cabinet, the R-112SW is built to resist unwanted resonance and vibration. The enclosure is finished in a brushed black polymer veneer, giving it a luxurious yet subtle look that fits into any modern or classic interior.

The included removable magnetic grille lets you choose between a sleek, minimalist front or showcasing the copper woofer for a bold, high-performance statement.
