Designed around
its application.
The array is intended for applications where system scale, placement and low-frequency requirements justify a substantial dedicated bass column. Room integration is part of the specification discussion.

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.
