Product Details

Dayton Audio RS100-4 4" Reference Full-Range Driver 4 Ohm

The Dayton Audio Reference Series sets a new standard of value in high-performance loudspeaker drivers. Utilizing a low-distortion motor system with two short-circuit paths and a rigid aluminum cone, the Reference Series can outperform drivers that cost several times the price. Their low-distortion characteristics and high excursion capabilities provide exceptional clarity, detail, and dynamics. Woofer features a black anodized cone, heavy-duty 6-hole cast frame, low-loss rubber surround, solid aluminum phase plug, and gold terminals.

Dayton Audio RS100-4 4" Reference Full-Range Driver 4 Ohm
Dayton Audio RS100-4 4" Reference Full-Range Driver 4 Ohm is rated 4.4375 out of 5 by 32.
Rated 4 out of 5 by from Better than MINI factoryReplaced 4" MINI cooper door speakers with these , far better than tiny magnet and paper stock. I used a bass stopper as well as I used a 6.75 bass speaker in lower door so wanted more of the mid range only as I have alpine tweeters in a pillars. Had to make a custom clamp to mount as the outer edge is not as wide as stock. They can take my stock head unit at max with no distortion.

Rated 5 out of 5 by from Drop-in replacement for Mini Cooper F56 2015Used this to replace the three front speakers (doors and center) on a Mini Cooper equipped with a Harman Kardon upgrade. The ideal solution would have been to use an aftermarket amplifier to power these, but then there was the cost issue. This replacements were installed very quickly using a home made adapter. They sound much better than the original ones, but they cannot overcome the EQ coming from the HK system. If one just want a marked improvement in the sound, knowing the limitations of the source, these are good.As for how they sound, I was trying to correct the known mid-range deficiencies associated with the HK upgrade. And although I could not fix all the problems, the overall result is a more pleasant mid level. I used some dampening and foam in the doors to eliminate potential distortion from the metal and plastic panels. With the making of adapters, opening side panels, connectors and everything else, it took me 2.5 hours.

Rated 5 out of 5 by from Mighty MidI installed these in a snug speaker cluster with the RS-108 and the Vifa dual magnet tweeter in the front car doors. No rear speakers. I have 4 Alpine PDX amps and the Alpine PXA H800 processor. All running from the stock head unit. I have the mids crossed from 300hz to 3500khz with 60 watts each. Also a 24db slope. These speakers are stunning and 10 times more once broken in! With this set up I will without a doubt began competing. Vocals are extremely balanced and the sound is like hearing music and not a speaker! I also have Dayton Audio 12" subs. Dayton has exceeded my expectations by far!!! If you haven't tried these you are missing out! Real music :-)

Rated 4 out of 5 by from ArticulateMy son called it the best-sounding car stereo system he's ever heard in his 22 years of life! I like the minimalist idea of having one driver to reproduce everything but the low end. Sparkle is missing from the high end.

What sizes are the crimp terminals on the RS100?

Asked by: ecks172
.205 for the (+) and .110 for the (-)

Would these work better in a sealed or open enclosure. Would like to build a simple speaker with these. Two cabinets with 2 drivers each. Any thoughts ?

Asked by: cptsoap
This depends on your taste for sound. A sealed enclosure will provide more of a solid low end from them, but an open backed enclosure will have a completely different tonality. You might want to experiment, there is no definitive right or wrong answer here unfortunately.

What is the diameter of the magnet on this driver?  I'm trying to determine if it will fit in the door enclosure of my car.  I assume the magnet is smaller than the "baffle cutout" which should be dictated by the basket.

Asked by: Chris K
magnet diameter is 70mm ( 2.75")

I see this has a phase plug, and possibly a mounting hole on the back. Could this be removed and replaced with a coax type tweeter? I know of a Focal 2 way crossover that comes with a "plug in" tweeter that is made to do this.

Asked by: TimmyJo
These phase plugs are glued in place and not easily removed. We do not recommend this as it will void the warranty and potentially damage the woofer.

I want to mount a pair of these in the dash of my 2015 Chrysler 200. They'll be actively crossed over at 24db (high pass). Will these go down to 250Hz in a free air situation? If not, can I use an adequate "soft" enclosure? At what size?

Asked by: TimmyJo
Yes these will handle a crossover that low free air without a problem.

If I use Sonic Barrier 1/2" Acoustic Sound Damping Foam, do I have to deduct anything from the internal volume calculations for the cabinet?

Asked by: Milty
No, that is open celled foam so it will have very little effect on the volume of the enclosure.
