Gemini STU-301BTB 3.5" 3-way outdoor speaker pair 200W Bluetooth 5.3 IP44 black

Outdoor Bluetooth 5.3 speaker system

The Gemini STU-301BTB is a paired active and passive outdoor speaker system designed for patios, decks and covered porches. It uses Bluetooth 5.3 for wireless streaming up to 33 feet and includes a 3.5 mm auxiliary input for wired sources. The IP44-rated ABS cabinets with butyl rubber surrounds resist rain and dust in marine-grade environments. Mounting brackets and a 2.5 metre speaker cable are supplied for straightforward wall installation.

Upgrade from single portable units

This system replaces standalone battery speakers that lack sustained output and weather sealing. The 200 watt three-way design adds a dedicated 1.0 inch dome tweeter and 3.5 inch injection cone woofer plus a bass reflex vent for deeper low-frequency response. The jump is worth it when you need consistent stereo coverage across a larger outdoor area without recharging batteries or moving hardware between locations.

Sustained output in fixed installations

Under continuous playback the corded 12 V 3 A power supply feeds the active module directly, avoiding the voltage sag common in battery-powered units. The 4 ohm nominal impedance and bass reflex vent help maintain low-frequency headroom during extended sessions. The sealed cabinet and rubber surround protect the 6.5 inch driver assembly from moisture ingress that would degrade performance over time in exposed mounting positions.
