Active Column Speaker [Aluminum Alloy Waterproof/Slave]

VL-T802 / VL-T802F / VL-T804 / VL-T804F is a series of active weatherproof column loudspeakers with aluminum enclosures, designed for self-powered outdoor and semi-outdoor public address and background music systems. The VL-T802 and VL-T804 are powered main units delivering 20W and 40W at 8Ω, each with AUX input and a dedicated power output channel to drive matching passive extension speakers (VL-T802F and VL-T804F). Both main models accept optional Bluetooth / TF / USB modules and run from a universal AC 100–240V adapter. Combining two or four 4-inch waterproof full-range woofers with a 1.5-inch tweeter, the series delivers 94 dB sensitivity and a 100 Hz–15 kHz frequency response. Enclosures measure 150 × 103 × 395 mm (2.6/2.5 kg) and 150 × 103 × 650 mm (4.0/3.5 kg), making them ideal for courtyards, cafes, retail stores, classrooms and outdoor perimeter applications requiring plug-and-play all-weather audio.
