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.

Frequently Asked Questions
What are the installation requirements and cutout size?
The Control 312CS requires a 14.9-inch by 14.9-inch ceiling cutout and mounts with a pre-mounted 14.4-inch square ported metal baffle. Installation depth is 6.3 inches, making it practical for retrofit applications in existing ceiling cavities.
How does the frequency response perform in live or installed systems?
The subwoofer covers 34 Hz to 3.5 kHz at ±3 dB, with extended response down to 30 Hz at –10 dB, providing articulate bass that integrates with full-range loudspeaker systems without muddying the midrange. Sensitivity ranges from 99 dB (near corner) to 93 dB (ceiling center), ensuring consistent output across mounting positions.
What kind of power handling and maximum SPL can I expect?
The 12-inch Kevlar-reinforced woofer with 75 mm voice coil handles 400 watts continuously with a maximum SPL of 125 dB at 1 meter, or 131 dB peak at the center of ceiling. The high-temperature voice coil and saturated-gap magnet design ensure reliable performance under sustained high-output conditions.
What makes this subwoofer suitable for professional installations over home use?
The Control 312CS is engineered for commercial and architectural applications, with in-ceiling installation, high sensitivity, and sustained SPL capability that serve venues and installed sound systems. It is not intended for home recording or practice environments where compact, close-field monitoring is the priority.
How does the well-damped surround design affect bass response?
The extended excursion design with well-damped surround minimizes distortion across the bass spectrum, delivering tight, controlled low-end articulation even at high output levels. This approach ensures the subwoofer maintains clarity and definition in demanding live and commercial sound reinforcement applications.
