The Avantone Pro CLA-Sub is a 300-watt 10" studio subwoofer designed to deliver clean, accurate low-end for modern studios and home theater setups. Built with flexibility in mind, this subwoofer adapts to your environment with two firing modes, front-firing for cleaner playback or downward-firing for increased output (+3 dB), allowing users to tailor performance based on room acoustics.

At its core is Avantone’s exclusive dual-magnet driver, a custom design built to minimize distortion and maximize output. Unlike some designs that add harmonic distortion for the sake of loudness, the CLA-Sub prioritizes clarity and accurate reproduction. Its rigid paper cone contributes to fast transient response while maintaining control over unwanted coloration.
Useful features include:
- Sweepable high-cut control (50–180 Hz) to set the crossover point
- Selectable low-cut filters (80 or 100 Hz) for through output to studio monitors
- Phase and gain controls for better system integration
- Switchable standby mode to reduce power consumption after 30 minutes of inactivity
- Footswitch compatibility for quick A/B comparisons
- Locking XLR/TRS combo inputs for secure audio connections
The CLA-Sub’s ported enclosure extends the low end even further, and repositionable feet include vibration-dampening material to reduce unwanted resonance, eliminating the need for separate isolation pads. Though it pairs naturally with Avantone’s CLA-series monitors, it integrates easily with most professional setups or even home cinema systems.
