JBL Control 312CS 12" High Output In-ceiling Subwoofer

JBL Control 312CS 12" High Output In-ceiling Subwoofer

The Control 312CS is a purpose-built in-ceiling subwoofer engineered for studio and control-room environments where low-frequency extension and output capability are essential. Its compact footprint and high sensitivity make it practical for retrofit installations in existing spaces while delivering the bass response and SPL required for accurate monitoring and mixing in medium to large rooms.

Driver & Power Handling

A Kevlar-reinforced 300 mm (12 inch) woofer with 75 mm voice coil handles 400 Watts of power with a well-damped surround and extended excursion design that minimizes distortion across the bass spectrum. The high-temperature voice coil and saturated-gap magnet geometry ensure reliable performance during extended mixing and mastering sessions.

Output & Frequency Response

With sensitivity ratings of 99 dB (near corner) to 93 dB (ceiling center), this subwoofer achieves maximum SPL of 125 dB at 1 meter (131 dB peak), integrating effectively with studio monitor systems in medium to large control rooms. The frequency response of 34 Hz to 3.5 kHz (±3 dB) provides tight, articulate bass without masking midrange detail—critical for accurate mix translation and decision-making.
