D&B Q1 Line Array Box


Category: Tag:


This line array loudspeaker is used in vertical columns. Its cabinet is a passive 2-way design that houses two 10” LF drivers and a 1.3” HF compression driver with a toroidal waveshaping device to achieve a 75° horizontal dispersion characteristic. The two 10” neodymium LF drivers are positioned in a dipolar arrangement providing an exceptional dispersion control even at lower frequencies, with the 75° nominal dispersion angle being maintained down to 400 Hz.

Q1 speakers can be combined with the Q subwoofer system inline array setups with the Q-SUB flown on top of the array or as a separate column, or in ground-stacked applications where the Q-SUB also mechanically supports the Q1s. The Q-SUB extends the system frequency response to below 40 Hz; for further extension of bandwidth and headroom, ground-stacked B2 subwoofers can be used (driven in INFRA mode). Q1 speakers can also be arrayed with Q7 and Q10 speakers; an ideal companion to all of these speakers is d&b’s D12 amplifier.

The Q1 cabinet is marine plywood with an impact resistant paint finish. The front of the cabinet is protected by a rigid metal grill covered with a replaceable, acoustically transparent foam. The cabinet incorporates a pair of handles, and mounted on the rear panel are two EP5 or NL4 connectors wired in parallel.
