2.1  Product description
The 44S is a passive 2-way design housing two 4.5” neodymium

LF drivers built into a bass-reflex design and two 1.25" HF dome

tweeters mounted on a rotatable CD horn thus providing rotatable

dispersion characteristics (h x v) of 90° x 30° and 30° x 90°

respectively.
The frequency response extends from 90 Hz to 17 kHz.
The loudspeaker can be used as a stand-alone system or

supplemented by actively driven d&b subwoofers.

The 44S is a highly directive ultra compact loudspeaker with an

asymmetric cabinet shape. In horizontal orientation, the 44S can

be used as a frontfill loudspeaker.

The enclosure is injection molded with an impact resistant paint

finish. The front of the cabinet is protected by a rigid metal grill.
Two M8 threaded inserts are incorporated in the back panel to

connect to different rigging accessories.

Different brackets enable mounting to walls, under ceilings or

balconies or any other suitable surfaces such as floors as a single

unit (Z5423/Z5424) or in closely coupled clusters of two cabinets

(Z5423 with Z5425).
Using the swivel bracket (Z5426), it can be used as a main or fill

system, flown or mounted on a high stand.

The optional d&b Z5427 44S Backbox is a solution for flush

mounting the loudspeaker into ceilings or walls, either in horizontal

or vertical position. The back box is just 140 mm high making it an

ideal solution for in-stair mounting.
Within the back box, the loudspeaker can be aligned by 20° in

5° increments.
