More features

Hardware for ADP-12S



The ADP-12S cabinet is constructed from 11-ply premium birch plywood (15mm thickness) and finished with polyurea coating


Internal design

The internal structure of the ADP-12S is heavily braced for greater longevity and all parts are assembled on metal inserts with metric screws. The amplification modules & DSP are housed in a separate chamber to the drivers avoiding excessive heat & vibration, thus delivering greater efficiency and reliability.


Rear panel

The powder coated steel rear panel contains all connections and houses the ADP-12S amplification modules and DSP, is easily accessible and housed separately from the drivers for increased reliability and efficiency



The ADP-12S has a heavy duty, powder coated front grille with a special acoustic rear fabric to protect the transducers against dust and dirt.



One ergonomic, die cast handle with firm internal grips is located on each side of the ADP-12S enclosure to facilitate transport, positioning and loading of the cabinets.


It uses one 12” (4” ISV voice coil) neodymium transducer with double spider (for improved linearity) in direct radiation bass reflex configuration.

Low frequency transducer with rubber surround, Doped Nomex® suspension, double spider for improved control and linearity and a 4” Interleaved sandwich voice coil.

Weather protected membrane for outdoor use.

Accessories for ADP-12S
35mm connecting pole for satellite combination between ADP-12S and ADP full range cabinets
