Engineered for rock-solid reliability day in, day out this passive 2-way loudspeaker is a truly professional performer. With its multi-purpose bass reflex construction it is equally suitable for fullrange, satellite or monitor use in live PA systems and permanent installations. The Stinger® 28 G3 boasts a mighty 400 watts RMS power handling and 125 dB maximum sound pressure. It is loaded with dual custom designed 8” woofers and a BMS compression driver delivering a punchy low end and smooth, crisp highs. The HF waveguide has been designed using BEM, the numerical modeling of sound radiation and propagation. It reduces floor and ceiling reflections, effectively eliminates side lobes and achieves a controlled uniform coverage pattern.

The Stinger® 28 G3 is designed to be a real workhorse throughout. The enclosure is made of rigid birch ply and coated with ultra tough polyurea for extraordinary strength and durability. Sporting a steel front grille, Dual-Tilt pole receptacle, multiple suspension points and ergonomic handles the Stinger® 28 G3 is an attractively priced choice for truly professional sound reinforcement. A large selection of accessories facilitate live and installed applications.

The Monitor 88 is the result of extensive research in the development of new transducers and crossover design. The result is a product with exceptional fidelity, the ability to produce deep controlled bass and extended high frequencies without sacrificing efficiency.
The low-frequency 8“driver ʼs low-mass, carbon fiber diaphragm remains extremely rigid at high power levels,producing a more linear response and lower distortion.
The high-frequency section features a constant directivity horn with a built-in mechanical phase equalizer.
The horn is driven by a Ferrofluid® cooled,1“titanium dome tweeter.
All components are housed in a vented enclosure formed from semiexpanded polystyrene foam.
The speaker system is available in black (Monitor 88)or white (Monitor 88W).

50The AC18/26 is a compact, fullrange loudspeaker system designed to provide maximum bandwidth and SPL in a single system package and be visually unobtrusive.  The enclosure design allows for installation very close to walls and ceilings, making it ideal for installation under balconies, columns, or for wall mounting.  The high frequency device is a 1" exit compression driver integrated into a 120° x 60° rotatable PT™ (Progressive Transition) waveguide that provides even coverage throughout the intended listening area.  The AC18/26 utilizes a 8" Symmetrical Field Geometry (SFG™) LF Transducer with a copper-clad aluminum edge wound 2.5" voice coil and a copper-capped pole piece that improves performance by reducing voice coil inductance and distortion.
The multi-ply hardwood enclosure is designed to work in the vertical plane as well as in the horizontal plane. Mounting points are provided for an optional U-bracket and for an OmniMount® type bracket.  The AC18/26 is also equipped with attachment
points located on the bottom of the enclosure for a stand mount accessory.  The plywood enclosure features JBLʼs DuraFlex™ finish and comes with a powder coated steel, foam-backed grille.
