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 P4228 is a weatherproof full range, wide-dispersion, two way loudspeaker system offering substantial power and efficiency for a variety of professional indoor or outdoor applications.

The high frequency section is a constant directivity CMD horn loaded with a 1.4” RCF Precision Neodymium compression driver with a 2.5” diaphragm assembly for smooth, wide dispersion. The low-frequency transducer is a double 8” woofer with a 2.5” voice coil.  The cabinet is asingle piece rotational moulded in medium density polyethylene, full UV protected. The cabinet is equipped with 4 x M8 brass inserts, a stainless steel U-Bracket. The front logo is in aluminium and rotatable. The grille is in custom perforated aluminium with open-cell fibres and water repellent woven fabric backing. P 4228 is suitable for indoor and outdoor applications/installations, it meets the requirements of IP 55 code (International Protection Rating).

The D 8 is a light-weight, robust 8“/1”, 2-way plastic cabinet for professional sound reinforcement applications. With a variety of suspension accessories and conservative cosmetics, the D 8 is ideally suited to be used in demanding fixed installations.
The cabinet is manufactured from ABS and therefore is extremely resistant against abuse on the road. For low and mid frequencies a DYNACORD DND8200-8 neodymium transducer is used. The Electro-Voice DH3 driver is used for the projection of the high frequencies. The Constant-Directivity HF horn has been integrated into the baffle by CAD methods. The nominal coverage angle of the cabinet is 90°*90°, horizontal*vertical, respectively.
Power handling of the cabinet is 250 W (rated) and 1000W (peak). The maximum sound pressure level is 124 dB, the frequency range of the D 8 is from 65Hz to 20kHz. The D 8 is ideally suited for applications as full-range cabinet or as Mid-Hi cabinet in high-performance small-format active and passive satellite systems.
Every transducer is protected against short-term thermal overload with thermal cutout switches and halogen protectors. In case of a potential thermal overload the power applied to the speakers is reduced to a safe level. The protection exhibits ʽsoftʼ switching characteristics, so no annoying clicks or pops are audible. The circuitry automatically resets after the voice coil temperature has reached a safe value.
Extremely durable acoustic foam mounted to a strong powder-coated steel grille protects the loudspeaker components against any mechanical damage. The trapezoidally shaped enclosure also allows employing the cabinet in monitoring applications. A stable, integrated carrying handle and the integrated stand socket for pole-mount stands allow easy transportation and set-up. A protective cover is available as an optional accessory.
