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 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 CE40P-8 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 a paper cone with mylar
dust cap, rubber surround, textile spider, high-performance neodymium motor, and
a steel frame with dual mounting lobes for conventional mounting.
