Vision SP-1800Wall Speaker & TC3Amp

Vision SP-1800 & TC3 Amp — matched wall speaker and amplifier bundle combining the Vision SP-1800 3-way passive loudspeaker with the TC3 Techconnect Amp Module for a complete, self-contained room audio solution.

The SP-1800 is a compact, three-way passive wall speaker — a 5.25-inch woofer, squawker, and tweeter share the sonic range to reduce distortion and deliver clear, full-range sound in classrooms, boardrooms, and meeting rooms. A bass reflex port extends the low end, and an adjustable C bracket tilts the speaker up or down 30 degrees for optimal coverage. The SP-1800 is passive (no built-in amp), so it pairs directly with the included TC3 Amp Module.

The TC3 Amp Module is a D-class amplifier that slots into a Techconnect double-gang surround. It outputs 2×25W RMS at 8 ohms and can drive a 4-ohm load — enough to power up to four 8-ohm speakers. The front panel 3.5mm input provides a convenient local connection point; two rear phoenix connector inputs accommodate fixed wiring. A preset memory function restores volume and input settings on power-up, and a remote control is included with both front and rear IR receivers for control system integration. Speaker cable and short input cables are included.
