The WLA-28A is an active two-way line array element pairing two 8" low-frequency drivers with a neodymium compression driver and titanium diaphragm behind a CAST waveguide. It reaches 132 dB maximum SPL with a 60 Hz–20 kHz (±3 dB) response and 100° horizontal coverage. Class D amplification, DSP with 8 FIR presets, and USB and RS485 connections are built in, and 3-point integral rigging supports flying or ground use.
