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 C3108 is a full range extremely versatile wide-dispersion, low profile, two-way loudspeaker system for near field applications.

Its compact size makes it ideal for low visibility side wall mounting.
The high-frequency section is a constant directivity horn loaded to a 1” neodymium compression driver with a 1.5” diaphragm assembly for smooth, wide dispersion. The low-frequency transducer is an 8” woofer with a 2” voice coil.
 

The C4128 is a full range 2 way high sensitivity, dual woofer passive system, compact and versatile specially designed for under balcony applications.

It is designed to provide extended low frequency performance from a compact, vented enclosure. It features advanced technology transducers: two 8" woofers equipped with a 2" voice coil and a 1" neodymium compression driver equipped with a 1.5" voice coil. The compression driver is mounted on a rotatable 90 x 70 constant directivity horn, providing very natural sound reproduction.
The cabinet is asymmetric (15° and 45°) for versatile under balcony applications as well as ceiling/wall installation and floor monitoring operations.
The wide coverage angle and the true constant directivity of the newly designed horn make very easy the coverage of large audiences.

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.
