Beatline 28

Two-way passive reflex with dual bass drivers

AVAILABLE IN CHINA ONLY

The Bealtline28 is a two-way, dual-bass driver, passive loudspeakerdesigned to give extended LF performance from a compact,architecturally neutral, vented enclosure. It features dual8”(200mm) long-throw, 2”(50mm) coil direct-radiating bass unitsand a 1.7”(44mm) diaphragm, 1”(25mm) exit compression driver,mounted on a proprietary, rotatable 90° x 50° constant directivityhorn.

Below 250Hz both LF drivers operate together whilst above250Hz only the upper LF driver is used to reproduce frequenciesup to the crossover point. This technique avoids the uneven polarresponse which would occur if both drivers were operated overthe same frequency band. The LF drivers are also fitted with fluxdemodulation rings, which reduce intermodulation distortion, inorder to preserve midband clarity at high signal levels.
