Q1 loudspeaker

The Q1 is a passive two-way loudspeaker housing two 10″ LF drivers positioned in a dipolar arrangement and a 1.3″ HF compression driver fitted to a toroidal wave shaping device. The 75° constant directivity horizontal dispersion pattern is maintained down to 400 Hz, while the vertical HF dispersion of 15° allows the Q1 to be used to construct vertical columns that produce a curved coherent wave front. The mechanical and acoustical design of the cabinet enables vertical splay angles to be set between 0° and 14°. Q1 cabinets can therefore be used in vertical configurations starting from two cabinets with a 15° to 30° dispersion, up to twenty cabinets with a fully user and venue defined vertical profile. The Q1 cabinet is constructed from marine plywood, incorporates a pair of handles and has an impact resistant paint finish. The front of the loudspeaker is protected by a rigid metal grill covered with replaceable acoustically transparent foam, and two EP5 or NL4 connectors wired in parallel are mounted on the rear panel.

Amplifiers

The Q1 can be driven either by d&b’s D6 or D12 dual channel power amplifiers configured for the Q1. More detailed information on specific loudspeaker setups with d&b amplifiers is available either in the relevant loudspeaker or amplifier manuals.
