XSL-SUB Architectural specifications

The subwoofer system shall be a 2-way bass-reflex design housing two long excursion neodymium drivers. One 18" driver radiates towards the front while one 12" driver radiates towards rear to produce a cardioid dispersion pattern. The front and rear drivers of the subwoofer shall be driven by separate channels of a dedicated and compatible amplifier, containing loudspeaker specific configurations and algorithms to provide cardioid behavior. The subwoofer shall exhibit extremely low power compression using very large vents.
The enclosure shall be constructed from marine plywood with an impact resistant and weather protecting PCP (Polyurea Cabinet Protection) finish. The cabinet front shall be protected by a perforated steel grill backed with an acoustically transparent foam.On the bottom panel two runners shall extend from the rear to the front panel of the cabinet protecting the bottom panel against scratching. Two correspondingly shaped recesses shall be incorporated in the top panel of each cabinet to accept these runners and prevent cabinet movement when stacking. The cabinet shall incorporate a three point rigging and shall be capable of suspending the subwoofer as pure SUB column or in mixed arrays with dedicated TOP cabinets below the SUB cabinets.A vertical splay of 2.5° between the front of adjacent SUB cabinets shall be mechanically adjustable.Each side panel shall incorporate two handles while on the rear panel four heavy duty wheels shall be provided.
The power handling of the forward driver shall be 700/1500 W while the power handling of rear facing driver shall be 400/800 W (RMS/peak 10 ms).
The frequency response (–5 dB) measured on axis shall extend from 37 Hz - 110 Hz in standard mode and from 35 Hz - 85 Hz in INFRA mode with a maximum sound pressure level (SPLmax peak/1 m) of at least 137 dB.
The connection panel on the back shall be recessed and fitted with a speakON NLT4 F/M connector plate.
The dimensions (W x H x D) shall not exceed 700 x 560 x 897 mm (27.5" x 22.1" x 35.3") and shall weigh no more than 66 kg (146 lb).

The loudspeaker shall be the XSL-SUB by: d&b audiotechnik GmbH & Co. KG.
