Pure Bass Power – Cerametallic™ 12” Woofer

The star of the SPL-120 is its 12-inch Cerametallic™ cone woofer, Klipsch’s proprietary material known for its exceptional stiffness-to-weight ratio. This premium driver design allows for fast, responsive movement without flexing, ensuring clean, distortion-free bass even at high output levels.

The large surface area of the 12″ cone moves more air, providing deeper and more impactful bass extension — perfect for large rooms or full-scale home cinema setups.

---

Class D Amplification – 300W RMS of Clean Power

Driving the SPL-120 is a highly efficient Class D amplifier capable of delivering 300 watts of continuous power and up to 600 watts peak. This gives the subwoofer exceptional headroom to reproduce sudden bursts of bass in movie scenes, musical drops, or game sound effects without clipping or distortion.

Despite the power, the Class D architecture ensures energy efficiency, low heat, and long-term reliability.

---

Slot Ported Enclosure – Deep Bass with Less Noise

To complement the woofer and amp, the SPL-120 features a front-firing slot port designed with internal flare geometry that reduces port turbulence and noise. This design allows for smooth airflow, minimizes “chuffing,” and enhances bass extension and accuracy.

The front port also means the SPL-120 can be placed closer to walls or in media consoles, giving you more flexibility in room layout without sacrificing performance.

---

Adjustable Crossover, Phase & Gain Controls

The SPL-120 offers user-friendly controls to integrate with any system:

• Low-Pass Crossover (40Hz–160Hz): Tailor the bass to blend seamlessly with your main speakers.

• Phase Control (0°/180°): Align the timing of the subwoofer with your speakers for tighter sound.

• Gain Control: Adjust output level to suit your space and preferences.

Whether you’re pairing it with bookshelf speakers or towers, you’ll achieve a smooth, coherent low-end transition with total customization.

---

LFE & Line Inputs – Wide Compatibility

The rear panel of the SPL-120 includes LFE (Low-Frequency Effects) and Line Level RCA inputs, allowing for easy integration with virtually any AV receiver or stereo amplifier. LFE bypasses the internal crossover and lets your receiver manage bass distribution, while the line-in gives you control with analog preamp connections.

The SPL-120 supports both home theater setups and dedicated stereo systems, offering maximum flexibility.

---

Wireless Option with WA-2 Compatibility

Don’t want to run a long RCA cable across your room? The SPL-120 is WA-2 wireless ready, allowing it to connect wirelessly to any compatible Klipsch system using the optional WA-2 kit (sold separately). This makes for a cleaner, clutter-free installation without compromising on sound quality or response time.

It’s ideal for flexible subwoofer placement, whether behind a couch, beside a console, or anywhere in the room.

---

Built to Perform & Impress

Finished in a premium brushed black polymer veneer, the SPL-120 is built with a reinforced MDF cabinet that minimizes resonance and adds visual elegance to your home theater or living room. The copper woofer cone adds a signature Klipsch touch that screams performance and luxury.

The magnetic grille is removable, letting you choose between a modern, clean look or the bold statement of the exposed copper driver.

---

• Medium to large home theater systems
