Dayton Audio CE Series CE46P-4 1-7/8" Paper Full Range Driver

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 CE46P-4 provides exceptional range with surprising bass, plus features you’d expect from a much larger driver. Its high-quality design features a paper cone, generous rubber surround, textile spider, high-performance neodymium motor, and an injection-molded frame with gasket for conventional front or rear mounting. It’s perfect for multimedia applications, product displays, miniature speakers, and line arrays.

Dayton Audio CE Series CE46P-4 1-7/8" Paper Full Range Driver
Dayton Audio CE Series CE46P-4 1-7/8" Paper Full Range Driver is rated 4.5 out of 5 by 2.
Rated 5 out of 5 by from full, balanced toneHas anyone directly compared performance of this speaker vs the Visaton BF45-4 Ohm 1.8"? Dayton appears to be very similar, cost less than a third as much. After hearing Dayton I'm so impressed I can hardly imagine the Visaton being much better.

Rated 4 out of 5 by from Good for its sizeThis speaker has surprisingly good range and decent sensitivity for its size. It's a good match for very low-power class D or T amps that are 4-ohm stable. I plan on using it with a tiny PAM8403-based 3W stereo amp to make a USB/battery-powered speaker to use with mobile devices.

What would be the recommended sealed box size for 4 of these? What low end response would I get out of that recommend box? (Building my first portable speaker setup)

Asked by: Crisrmz
The recommended sealed volume for four of these would be 0.06 cubic feet (1.72 liters) for an F3 of 150 Hz.

In my previous question regarding two of these in a ported enclosure, you said 1.3 L (0.46 cuft). I assume you meant .046 cuft for the pair, correct? 

Asked by: MarkSLC
Yes, 0.046 cubic feet, I apologize.

The enclosure volume listed above for two of these with a 3" passive radiator works pretty well. What specs would I need to build for if I wanted to build a ported enclosure for two of these? Would I need to isolate the two drivers?

Asked by: markSLC
A total volume of 1.3 liters (0.46 cuft) with a 1" diameter, 4" long port will tune the box to about 100 Hz.

Which terminal is + and which is -? It's not on the speaker and much to my surprise connecting either terminal to + and - output seems to work. Can someone help me here?

Asked by: dcdiyaudio
Looking at the picture with the speaker facing up and the terminals toward you, the terminal on the left is positive.

Optimum sealed enclosure size?

I'm building a small portable stereo and using two of these in a sealed enclosure. What is the ideal enclosure volume for two of these?Alternatively, could the 3-1/2" peerless passive radiator be used in conjunction with two of these drivers to achieve an extended bass response? What would the recommended enclosure volume be in this scenario?Thank you.
Asked by: Jeff B
I would recommend a 0.03 cubic foot sealed enclosure for a pair of these, or 0.04 cubic feet if you wanted to use a passive radiator with them. A sealed box will give you an F3 of 144 Hz, if used with a passive they will extend to 120 Hz.
