The AQ28 is a two-way, dual-bass driver, passive loudspeaker
designed to give extended LF performance from a compact,
architecturally neutral, vented enclosure. It features dual
8”(200mm) long-throw, 2”(50mm) coil direct-radiating bass units
and a 1.7”(44mm) diaphragm, 1”(25mm) exit compression driver,
mounted on a proprietary, rotatable 90° x 50° constant directivity
horn.

Below 250Hz both LF drivers operate together whilst above
250Hz only the upper LF driver is used to reproduce frequencies
up to the crossover point. This technique avoids the uneven polar
response which would occur if both drivers were operated over
the same frequency band. The LF drivers are also fitted with flux
demodulation rings, which reduce intermodulation distortion, in
order to preserve midband clarity at high signal levels.
