KA-S9019‑AS Single‑19‑Inch Active Subwoofer Overview
Core Advantages
1. High‑Intensity Low‑Frequency Performance
It adopts a 19‑inch neodymium driver with a 4‑inch voice coil, delivering 2000W RMS power and a peak SPL of 138dB across 30Hz‑200Hz. The built‑in active amplifier removes external‑amplifier requirements, and its 4‑ohm impedance matches professional full‑range speakers perfectly.
2. Durable and Portable Construction
18mm birch plywood with polyurea paint minimizes cabinet resonance. Weighing only 53.4kg together with built‑in side handles facilitates easy handling for both touring events and permanent installation.

Application Scenarios
When paired with line‑array speaker systems, it delivers deep and forceful bass for stadium‑scale concerts, outdoor music festivals and large performance venues.
