Dayton Audio CE Series CE32A-4 1-1/4" Mini Speaker 4 Ohm

Dayton Audio is pleased to introduce the new Commercial Engineering (CE) Series of small loudspeaker drivers. Engineers, designers, and integrators will benefit from how effortlessly these speaker components satisfy the diverse demands associated with consumer electronics and audio-enabled projects

Multiple types and styles are available within the Dayton Audio CE Series driver family. Each was produced to provide excellent audio quality no matter what the overall system design goals may be, and to suit a wide spectrum of engineering requirements. These versatile yet economical loudspeakers are available in sizes from 28 mm (1-1/8") to 90 mm (3-1/2") in diameter, and with power ratings from 1.5 watts to 5 watts continuous RMS power.

The CE32A-4 provides features you’d expect from a much larger driver, in a size that’s perfect for miniature applications that require wide dispersion and rich, natural sound. Its high-quality design features an elegant black-anodized concave aluminum diaphragm, rubber surround, textile spider, high-output neodymium motor, and a square injection-molded frame drilled for conventional mounting.
