Review: Fantastic small drivers! - These are the best quality for price small full range speakers out there. I put them in folded Voigt pipes I built, and they surprise everyone with the quality and frequency range of their sound. Do make sure you note the exact measurements of the speakers as offered.
Review: Good sound - I'm using these in a smart speaker project and they are working out great. The sound is good. They aren't party speakers so don't expect booming bass out of them. Instead, pair them with a 4" passive radiator for the low end. These drive pretty loud and the mids are clear.

## Questions & Answers

**Q: Is that just a pointy metal cap on this thing or is it a tuned phase plug?**
A: It is a tuned phase plug, like all midrange and midbass drivers from the Dayton RS range. It's certainly not a dust cap. A dust cap moves with the cone. A phase plug is fixed to the magnet assembly and basket, and does not move.

**Q: What's the stated frequency response?**
A: Spec: http://www.daytonaudio.com/index.php/rs100-4-4-reference-full-range-driver-4-ohm.html
Impedance	4 ohms
Sensitivity	87.5 dB @ 2.83V/1m
Frequency Response	80 - 20,000 Hz
Voice Coil Diameter	25 mm
Magnet Weight	--
DC Resistance (Re)	3 ohms
Voice Coil Inductance (Le)	0.28 mH @ 1 kHz
Resonant Frequency (Fs)	84.8 Hz

**Q: Is this price per speaker?**
A: Price as shown for each speaker (plus shipping if applicable). ♫

**Q: What is the exact minimum and maximum width of the face in inches?**
A: If your asking about the dimensions of the speaker box face, the smaller the better, to minimize reflected sound.
I picked these drivers to make a full range (no crossover) transmission line. They are mounted vertically at the top of 4 Ft' long wool lined boxes,  Apx. 5" square.  They play into a wooden cone mounted slightly above the drivers, which creates a 360o sound-field. The boxes are slotted at the bottom rear (about the size of the cone area)  which enhances the bass by using the rooms corner walls. Over the years I have built Bass Reflex, Dancing woofer pairs, Di Eppilito configurations, and Folded horns. All of which was to achieve high sound pressure levels. The goal in this case was to try to achieve an undistorted, full sound spectrum, at moderated sound levels with a single driver.. These small drivers certainly filled the bill, and I feel one would have to spend significantly more money to attain a better sound using only  a full range driver. Hope this helps.
