PUI Audio AS04008CO-2-R 8Ω 1.5W 40x20mm Speaker

The AS04008CO-2-R is a compact general-purpose speaker from PUI Audio, intended for electronic applications where sound must be integrated into a small space.

With 8Ω impedance, 1.5W rated power and 3W maximum power, this speaker is suitable for small audio circuits, amplifier modules, portable equipment, control panels, sound signalling devices and repair of equipment using speakers with similar characteristics.

The oval shape with rectangular frame, 40 x 20mm dimensions and 8mm maximum height allow integration into compact enclosures, panels, boards or suitable mechanical supports. The top sound port helps audio output when the speaker is mounted behind grilles, openings or dedicated areas in the equipment housing.

The listed frequency range is 200Hz to 20kHz, with 84dB sensitivity measured at 1W/500mm, making it suitable for voice reproduction, warning tones, alerts, low-power audio and general sound applications.

The solder eyelet termination makes wire connection straightforward, making this speaker a practical choice for prototypes, maintenance, replacement and integration into electronic projects.

Important note

Before use, always confirm the impedance, rated power, maximum power, physical dimensions, available height, mounting method, termination and compatibility with the audio circuit.

The AS04008CO-2-R is a compact 8Ω speaker and should be used with amplifiers or audio circuits suitable for its power rating. Excessive power may cause distortion, overheating or speaker damage.

For replacement in existing equipment, confirm whether the original speaker has compatible dimensions, impedance, power, depth and connection type. This item corresponds only to the PUI Audio AS04008CO-2-R speaker; wires, amplifier, acoustic enclosure and mounting accessories are not included unless expressly stated otherwise.
