SP-IR234 Passive Speaker with Infrared Sensor
A passive column speaker with a built-in 24-diode infrared sensor array. It combines loudspeaker and sensor functions in one aluminium enclosure, reducing separate ceiling sensors and cabling.
- Built-in 24-diode ultra-wide-angle infrared sensor array.
- Two 4-inch speaker units with 30 W rated power at 8 Ω.
- Covers a 26 m unobstructed reception radius.

Frequently Asked Questions
Which rooms is the SP-IR234 designed for?
The SP-IR234 is typically installed in classroom, lecture hall, training room, hybrid learning. Room size, ceiling height and speaker layout determine the final configuration — send us a floor plan and our team will recommend a layout.
How many infrared channels does the SP-IR234 support?
The SP-IR234 offers 2 selectable infrared channels. Several microphones can operate in the same room on separate channels; match each microphone and receiver to the same channel to avoid cross-talk.
What coverage does the SP-IR234 provide?
The rated coverage is R 26m(Unobstructed Distance). Infrared coverage depends on sensor placement and room geometry; an expansion sensor can be added where the room has shadowed areas.
What certifications and warranty are available for the SP-IR234?
Seekika Audio supplies CE, RoHS and FCC compliance documentation for its classroom audio products. Classroom audio products carry a standard 2-year warranty against manufacturing defects, with extended coverage available on project orders.
