Gemini TRD550 external speaker
The Gemini TRD550 is a compact external speaker designed for mobile transceivers, CB radios and ham radio equipment. It connects via a 3.5 mm plug on a 1.8 metre cable and delivers 5 W of power handling for clear voice communication. The 3 inch dynamic driver is housed in a lightweight plastic cabinet with an integrated mounting bracket.
3.5 mm auxiliary interface limits
The auxiliary connection provides a simple wired link that carries mono audio from the radio’s external speaker jack. Cable length is fixed at 1.8 metres, so placement is restricted to that radius from the transceiver. No wireless option, remote control or additional inputs are included, making the speaker a single-purpose add-on for radio gear.
5 W power handling decides fit
The 5 W rating determines whether the speaker matches your radio’s external audio output. Radios rated well above 5 W risk overdriving the driver, while lower-powered sets will operate cleanly. Impedance is 8 ohms and frequency response spans 27 Hz to 120 kHz, but the power figure is the primary spec to check before purchase.

Questions about this item
Should I choose the TRD550 or the ARIA926DW model number?
Both numbers refer to the same rectangular external speaker; TRD550 is the part number and ARIA926DW is the model label used by the manufacturer.
How loud will the 5 W power handling be in my vehicle?
The 5 W rating drives a 3‑inch dynamic driver through a 1.8 m cable, giving clear mono audio for CB, ham or scanner use inside a cab.
What does the 3.5 mm AUX connector limit in practice?
The 3.5 mm plug carries a mono signal only, so stereo sources will be summed to one channel and volume is controlled at the radio.
