At NAMM 2016 in Anaheim, JBL Professional by Harman introduced the new SUB18 studio subwoofer, designed to deliver the very high continuous output and extremely low frequency response required by music professionals in the EDM and hip-hop domains, as well as those working in film and post production.
Incorporating JBL’s 2269 low-frequency transducer with patented Differential Drive technology and specifically designed for studio use, SUB18 produces neutral low frequency response below 18 Hz, providing an accurate reference in the low frequency band and very high output. Peak output is statedf as137 dB.
The highest possible output and performance are obtained by powering the SUB18 with Crown iTech HD Series power amplifiers.
The heart of the SUB18 is the 2269H low-frequency transducer developed for use in club applications. With the 8,000-watt peak power handling capability, special technology was required for heat dissipation.
The Differential Drive design incorporates two 4-inch voice coils that share the thermal load, greatly reducing power compression and resulting non-linear output. The result is sustained linear output at higher SPL than otherwise possible and true sub-bass response. The 2269H is housed in a birch plywood enclosure that is only 24 inches deep, allowing placement behind film screens.
Used in conjunction with JBL M2 Master Reference monitors, the JBL SUB18 enables three times greater output from the system, allowing an M2 System to deliver the SPL required for large film post dubbing stages.
“The JBL SUB18 studio subwoofer channels our category-leading transducer and acoustic expertise to bring next generation performance to music and post production professionals,” says Peter Chaikin, Recording Solutions, Harman Professional Solutions Division. “Along with our flagship M2, the SUB18 allows Music and Post customers to have remarkable playback capabilities and room to room consistency in their facilities.”
