Designed around
its application.
The working alignment is deliberately low-Q, with DSP extension forming part of the system design. Placement, equalisation and output requirements must be considered together.
The downloadable sheet records design values and targets; it is not a measurement report.

Consider the room.
Then the numbers.
Low-frequency extension and maximum output depend on the system configuration, placement and test conditions. Current response and output figures are design targets, not published measurements of a completed production unit.
