The Sub 1.18 is the ideal bass extension for the Corus C 12.2 or C 15.2 full-range cabinets. In the low-frequency range between 38 Hz and 250 Hz an Electro-Voice EVS-18S woofer in direct-radiator bass-reflex design produces a max SPL of 130 dB. Thanks to their low-pass filter, the Sub 1.18 can be operated simply in parallel mode to existing full-range cabinets. Also recommended, naturally, is the combination with a DYNACORD DSP controller or amplifier for the creation of active two-way systems.

Equipped exclusively with high-quality components, A-Line loudspeakers stand apart in their class thanks to their high power-handling capacities and 15mm-thick plywood cabinets that are as light as they are robust. Their asymmetrical footprint also makes them a convenient option for floor monitors.

Impressively deep bass output from a powerful subwoofer with a beautiful exterior. Yamaha’s Advanced YST II (Yamaha Active Servo Technology II) combines negative-impedance and constant-current principles to drive the speaker cone with extremely tighter control. Using Advanced Negative Impedance Converter (ANIC) circuits, this system dynamically optimizes effective speaker impedance to maintain excellent linearity. This means more stable and accurate low range response, not to mention higher sound pressure levels. This means more stable and accurate low range response, higher sound pressure levels, and the ability to reproduce clear bass without muddiness.

The WL218-sw is a premium, high-performance, dual 18″ subwoofer designed for suspended or ground stacked use in the most demanding touring or installed concert applications. With an impressive combination of punch, low-frequency extension and accuracy, the WL218-sw is an ideal companion for QSC’s acclaimed WideLine? series as well as other professional sound reinforcement systems.

Features

• Simple, convenient suspension system based on the proven QSC WideLine design. Supports up to 8 WL218-sw subwoofers with 10:1 design factor
• Very high acoustic output capability – 139 dB SPL (1m) peak
• Exceptional “punch” combined with low-frequency extension down to 31 Hz
• Comprehensive transport and handling features including an easy to attach dolly and twelve thoughtfully placed handles
• Premium-grade, long-excursion, high-power woofers with 4″, fiberglass voice coils, double layer spiders and triple roll surrounds
• Birch ply enclosure with independent, dual chambers and extensive internal bracing for rigidity and solid, accurate reproduction

With an impressive combination of punch, low-frequency extension and musical accuracy, the QSC GP218-SW-BK is an ideal companion for the acclaimed QSC WideLine series as well as other professional sound reinforcement systems. For suspension in permanent installations each GP218-sw QSC passive subwoofer comes with a total of sixteen (16) threaded M10 inserts (four per side).

For ground-supported applications, the subwoofers may be stacked horizontally using their interlocking feet and recess features machined into the enclosure?s top panel.

The 18_ woofers incorporate a double layer spider and triple roll surround for extended and controlled excursion at extreme power. The 4_ voice coil is wound on a fiberglass former to prevent deformation at high operating temperatures and is extensively vented to reduce power compression. An aluminum demodulating ring is employed for low distortion.

First glance, the enclosure seems too small to even house its pair of 4_ voice-coil, long-excursion 12_ woofers, yet it produces 135 dB (peak) SPL and has LF extension to 32 Hz, with the punch needed for popular music. The extremely low profile of the WL212-sw sub (less than 15_) also makes it a great choice for installed and portable use under a stage or in other tight quarters. The 4th order bandpass design matches the width of the WideLine-8 elements allowing it to be flown inline with or behind a WideLine-8 array.

Premium materials are used throughout the system. The enclosure is constructed of Baltic birch plywood and coated in an environmentally friendly, waterborne polymer finish that is field repairable. Suspension fittings are made of aluminum to reduce weight and prevent rust.

The KS112 is the perfect choice for anyone needing high output, low-frequency extension in a highly compact, lightweight, and portable package. Powered by a 2000 watt class D amplifier module, KS112 features a single 12-inch transducer in a 6th order bandpass premium birch cabinet. On-board DSP provides variable crossover and savable/recallable Scenes for commonly-used applications while Intrinsic Correction? tuning and loudspeaker management maximizes performance and protects the subwoofer?s components.

Two M20 threaded pole receptacles provide a positive, wobble-free connection to a threaded speaker pole in either vertical or horizontal deployment (pole not included). An optional KS-LOC security cover prevents unauthorized tampering of controls. Rugged, low-noise casters are included.

Musicians, bands, mobile DJs, system integrators and AV rental/production professionals alike will appreciate the performance of the KS112 in a wide variety of applications ? particularly when paired with TouchMix Series mixers, further optimizing KS Series performance, or as a complement to K.2 Series loudspeakers.
