J212 & J218S: Professional 3-Way Dual 12″ Line Array System

2026-04-11

J218S – High-Output Dual 18″ Flyable Subwoofer

To complement the J212’s low-frequency extension and provide the visceral impact required for electronic music, live bands, and cinematic presentations, the J218S subwoofer is the ideal partner.

Subwoofer Highlights

Dual 18″ Long-Excursion Drivers High-bl factor and large voice coils deliver massive air movement with low distortion.

Front-Loaded Design Efficient and punchy, with extended response down to 48 Hz (±3 dB).

Cardioid Array Capability When stacked or flown in groups, J218S can be configured for cardioid directivity, reducing rear energy by over 3 dB – perfect for stage noise control.

Same Rigging Architecture The J218S integrates seamlessly into J212 arrays, flying directly behind or below the mains for a clean, scalable setup.

System Performance & Applications

The J212 + J218S combination achieves a balanced system response from 40 Hz to 18 kHz. A typical 2-way active configuration uses dedicated amplifier channels for LF (J212 low section + subs) and MF/HF, though full 3-way active processing is available for maximum control.

Ideal Use Cases

Large-Scale Touring

Permanent Installations

Corporate Events

Outdoor Broadcasts

(Festival main stages, arena concerts, nightclubs, houses of worship, and performing arts centers, high-intelligibility conferences, weather-resistant options).

Why Choose the J212 / J218S System?

High Output with Low Distortion – The dedicated 3-way design reduces intermodulation distortion common in 2-way dual-12″ arrays.

Predictable Coverage – The J8-inspired waveguide and cabinet shape allow precise simulation and real-world accuracy.

Scalable & Cost-Effective – Start with four J212 tops and two J218S subs for small/medium venues; expand to dozens per side for stadiums.

Trusted Build Quality – Heavy-duty steel grilles, recessed handles, and impact-resistant paint ensure years of reliable service.
