Loudspeaker Enclosure

1 x 12″ Bass Mid Driver +2″ Horn – 1060 Watts Program

Acoustic Technologies commitment to engineering superior loudspeaker products for the audio professional is evident in the new SS Series of loudspeaker systems. Designed for high end touring and production, the SS24 employs an extremely efficient 12” neodymium low frequency transducer and an advanced 2” exit neodymium H.F. compression driver coupled to a H.F. waveguide developed specifically for this cabinet.

The SS24 input switching allows either 2 way active or fully passive operation. The optimised internal crossover network provides a seamless transition between the system transducers. Crafted from the finest 18mm void free Finnish birch ply, the SS24 is built to withstand all the rigours of touring. The enclosure is finished in black AcoustiCoate with a powder coated steel grille, providing durable visually appealing finish. The SS24 features a versatile fly track rigging system and a pole mount adaptor

The end result is a truly professional loudspeaker system offering extremely high output with a smooth extended frequency response eminently suitable for all music and vocal reproduction.

The SS24 enclosure is constructed of high quality void free 18mm Finnish Birch Ply. The transducers are protected by a perforated steel mesh, lined with acoustically transparent foam, providing a durable visually appealing finish.

The SS24 passive crossover provides a seamless transition between the transducers. The crossover frequency is selected to enhance the already superb performance of the individual components. Great care is taken to ensure that a phase coherent output is maintained across the entire audio bandwidth.

Sensitivity, Maximum Power and SPL measurements are conducted in accordance with the AES 24 Hour Pink Noise Standard.
Acoustic Technologies reserve the right to alter or amend the SS24, without prior warning in the interests of product improvement.
