Product Description
The JBL Stage A120P is part of JBL’s renowned Stage Series, designed to bring professional audio quality to your living room. From thumping low-end punch to subtle ambient rumbles, the A120P reproduces bass with clarity, power, and control.
Its 12-inch (30.5 cm) polycellulose woofer is driven by a high-output amplifier, capable of producing 250 watts of continuous power and up to 500 watts at peak levels. The result? Deep and powerful bass that you can feel and hear.
The bass-reflex enclosure, optimized for airflow and reduced distortion, allows the A120P to deliver extended low frequencies with greater efficiency. Whether placed in a corner or integrated into a home theater system, it maintains sonic integrity across a wide range of genres and formats.
Immersive Low Frequencies
Enjoy the full spectrum of sound with a frequency response ranging from 32Hz to 150Hz. The A120P’s extended low-end capability ensures that every explosion, bassline, or rumble is faithfully reproduced. It adds an emotional depth to your audio experience that small speakers simply can’t match.
The adjustable low-pass crossover (50Hz to 150Hz) allows you to tailor the subwoofer’s output to match the performance of your main speakers, ensuring seamless integration.
Powered for Performance
With a built-in Class D amplifier, the A120P is ready to perform right out of the box. Its 250W RMS output delivers consistent, high-impact bass without the need for an external amp, while 500W peak power ensures headroom for dynamic scenes in movies or bass-heavy tracks.
JBL has fine-tuned the amplifier for maximum efficiency and minimal distortion, so you get pure, clean bass at any volume.
Smart Design and Easy Setup
The JBL Stage A120P is built with practicality in mind. Its RCA input (LFE) connects easily to AV receivers or preamps. You’ll also find rear-panel controls for volume, phase, and crossover frequency—everything you need to get the sound just right for your room.
Its bass-reflex port is positioned to minimize unwanted noise while enhancing airflow, and the robust MDF cabinet reduces resonance for cleaner performance.
Sleek and Compact Aesthetics
Finished in a classic black wood grain, the JBL Stage A120P blends elegantly into any décor. Its compact footprint allows for flexible placement without compromising performance. Measuring just 14.6 x 15.6 x 16.5 inches, it fits easily into tight spaces, while its solid construction ensures long-term reliability.
Energy Efficient and Environmentally Friendly
When not in use, the subwoofer’s auto-standby function reduces power consumption to just 0.5W, helping you save energy. During operation, it draws up to 335W, ensuring powerful output when you need it most without excessive power drain.
