JBL ASB6118-WH Single 18" Subwoofer
The ASB6118-WH is a heavyweight professional subwoofer engineered for consistent low-end reproduction in installed sound and live reinforcement applications. Its vented front-loaded design and substantial cabinet construction deliver controlled bass extension without the resonance issues common to sealed designs, making it a reliable foundation for full-range systems in mid-to-large venues.
Design & Build
Built from 16 mm exterior-grade 11-ply birch plywood, the cabinet resists flex and vibration while maintaining structural integrity under sustained high-output conditions. The 460 mm (18-inch) SVG Super Vented Gap driver with a 100 mm (4-inch) voice coil handles extended power without fatigue, and the front-mounted grille with acoustically transparent foam backing protects the driver while preserving frequency response. Weighing 98 lbs with M10 threaded suspension points, this unit integrates easily into flown or ground-stacked arrays.
Audio Performance
With 800W long-term power handling (3200W peak) and 98 dB system sensitivity, the ASB6118-WH generates 129 dB continuous SPL at 1 meter with 135 dB peak capability across its 35 Hz–1 kHz (±3 dB) frequency response. This performance envelope covers the critical low-frequency band (30–500 Hz) where the subwoofer must blend seamlessly with main speakers while delivering the impact modern live sound and installed systems demand.

Frequently Asked Questions
What does the vented front-loaded design do differently from a sealed sub?
Vented designs extend bass response lower and deliver more output in the critical 30–500 Hz band while avoiding the resonance peaks and boominess common to sealed cabinets. The ASB6118-WH's vented configuration delivers controlled, transparent bass that blends cleanly with main speakers in live and installed applications.
How much power does this subwoofer handle, and what's the difference between long-term and peak ratings?
The unit handles 800W long-term power (3200W peak) over 100 hours of continuous operation, and 1200W AES power (4800W peak) over 2-hour sessions. Long-term ratings ensure reliability during extended gigs or installed systems; peak ratings show headroom for dynamic impact during transient-heavy material.
What frequency range does it cover, and will it work with full-range speakers?
The ASB6118-WH covers 35 Hz to 1 kHz at ±3 dB, with extension down to 28 Hz at −10 dB, overlapping cleanly with main speakers at the crossover point. Its neutral, transparent response and high output (129 dB continuous SPL) make it ideal for blending with QSC, Electro-Voice, and Yamaha full-range systems.
How much does it weigh, and can it be flown or stacked?
The ASB6118-WH weighs 98 lbs and features M10 threaded suspension points for flying or integration into ground-stacked arrays. Its robust 11-ply birch cabinet resists flex under sustained output, making it reliable for both temporary event rigs and permanent installed systems.
What cabinet construction makes this unit durable for touring and permanent installs?
The cabinet is built from 16 mm exterior-grade 11-ply birch plywood with a 14-gauge perforated steel grille backed by acoustically transparent foam. This construction resists vibration and flexing during high-output operation, ensuring consistent performance across road use, venue installations, and long-term service.
