Dayton Audio RS100-8 4" Reference Full-Range Driver
Dayton Audio RS100-8 4" Reference Full-Range Driver is rated 4.3333 out of 5 by 12.
Rated 4 out of 5 by from Great 3" driver!First thing to note, Dayton measures the reference series by the outside edge of the baffle, not the speaker cone. This isn't a problem, as long as you know ahead of time. Many other speaker manufacturers do the same.As far as the sound of these, they sound great! I have them in a .06 cu ft "box" and they sound fantastic. With a little box tuning, they have an output response very close to the specified graph that Dayton provides. Off axis is a little weak on the top end, and obviously the bottom end is a little weak, but both are physical limitations of a 3-4" driver, not much you can do about it. I am using a pair of these on my desk at work, and love them. I got the Dayton 15w/ch amp and they get plenty loud and sound great doing it.

Rated 4 out of 5 by from As good as its source allowsI've used several of these in small acoustic suspension designs and with an appropriate high quality amplifier and source, they sound surprisingly good. They do require a little help in the low bass region where a small, quick subwoofer makes these little speakers sound authoritative and very clean. I thought the highs were a little harsh when I was powering them with a tripath amp, then came to realize that these little Daytons were just accurately presenting what they were fed. If you are looking to build a small bedroom or kitchen system, get good amplification having 30-50 watts per channel and a subwoofer. Have some fun cobbling together some small sealed boxes for these. I do like the sealed boxes better than the ported ones I've tried.

Rated 5 out of 5 by from Pretty good for a full range speakerI used two of these in a small enclosure (portable stereo)...they are great. Obviously they don't sound as good as they could when used in conjunction with a crossover, but they're some of the best small full-range speakers I've heard. Great value.

Rated 4 out of 5 by from Small package...... Big Sound!!!I bought a pair of these to put in a DIY shelf system project and I am very pleased with the outcome. These mighty midgets are nothing less than incredible! I plan on buying a pair of the 4 ohm version to squeeze every drop of power I can get out of my amp. The amp I am using is the Lepai 2020a tripath which is 20 watts rms and these speakers are rated at 30 watts so I am going to see what kind of performance boost I can get with the 4 ohm load.

Rated 5 out of 5 by from Nice little driverAt first I was not thrilled with it- it sounded a little tinny or nasally, but I think its broken in now and in conjunction with the rest of the system (HT) it sounds fantastic.My application is a little weird, I am using as a dedicated center ch. speaker in room with very little space in the center (imbedded into a fireplace cavity above a mantel and below the LCD tv.) i guess now that i know the modern receivers can simulate the L and R ch. to carry center channel info, I may not have bothered, but I did. I also switched receivers from a very old (and marginal quality JVC ) to a modern Integra brand and the sound quality improved over dramatically.Bottom line is this is perfect for voice info off TV broadcasts and even carries some musical info decent enough though in music mode I may just turn it off once I spend enough time figuring out the one million configuration options with the receiver. I bought a larger Nirvana (6.5") full range driver and though it sounded amazing it was just too darn big for the spot. this is small but fit the bill for what I am using it for nicely. just have to make sure you cross it over pretty high as its even smaller than the advertised 4" to low a signal may blow it if you turn it up. :

Rated 2 out of 5 by from I must be wrongI have several Dayton drivers and based on my RS180-4 7" drivers that I love, I though I'd give this a try to replace a ND-105 -4 4" driver I poked a hole in. First I should of looked at the specks more as this is not a 4" driver. Its at least 1 inch smaller than most other 4 inch drivers. And it sounds more like a 3 inch driver. Drum kicks are thin and off color. Looking at all the other reviews, obviously I must be wrong. Although the ND-104 is a mid bass driver, its additional 1 inch in diameter produces to me a far superior driver when I crossed the ND104 to make a suitable comparison. So as wrong as I am, I'll just say this is too small to be called a 4 inch. And apparently 1 inch is a dramatic (from 3 to 4 inches) step in sound as three other 4 inch drivers I threw in sounded better . I do like the way it looks.

One or two per tower speaker?

If I were to build a tower speaker using just this speaker supplemented by a powered (25wRMS) Dayton Classic 8" woofer in the lower chamber, would one of these drivers (per tower) suffice or would two be a notable improvement?Thanks.
Asked by: SmilodonCondor
One driver will give you point source imaging. With a sub that will create great sound staging. Additional drivers start to create unique challenges with regard to driver dispersion. My designs have always been either point source or line source. The exception is an MTM midrange which is typically horizontal.

sealed enclosure

I have a couple nice 0.3 cabinets I made and was wondering if this wad a good candidate. They will be used crossed over at 150Hz . If so, how much fill do I use per cabinet. If there are other drivers that would work better for my needs, could you please recommend.
Asked by: dtmoody
You need to eat up about .07cuft inside that box and tune it to 67hz.I did a very similar design a while back and really enjoyed it.Keep the power limit to 50w at that crossover and you should be good.

use in car

can this be used in a spot where my car has a 4" driver? and if so, should I get the 4 or 8 Ohm.thanx
Asked by: jalng63
Most car audio is 4 Ohm, so that's what you need. Aluminum cones can have "issues" in some spaces, so try them pretty quickly and if you aren't happy with the sound, return them to P_E with-in the 45 days. My parent's have a VW Vanagon that uses 4" door speakers, and you have my sympathies.

Smallest sealed box size

What would be the smallest size of a sealed box needed for this speaker? My application is for non-critical listening.
Asked by: jeezmo
The smallest I would put them in would be about 0.05 cubic feet.

Use as a mid?

After years of use/abuse I have a good quality crossover network at 700Hz/7000Hz (2nd order) and a reasonably good quality 12" woofer. I'm sick of the old box & want to start over. I was thinking of using the Dayton RS-100-8 as a midrange, and the Dayton DC28F-8 dome as my tweeter. Is the 7000 Hz cross too high for the RS100-8? Thanks much (in advance) for your time & response.
Asked by: Petri
I don't know why this driver would not work crossed over at 7 kHz. Looking at the specs, crossing over at 7k will avoid a rising high end above 10 kHz. You could use another tweeter other than the Dayton DC28F-8 because that tweeter does not need such a high crossover. I have nothing against the DC28F-8, in fact, I use them in my main system. But a 7k crossover allows you to use other tweeters that don't go as low as the DC28F-8.

is volume simply doubled for two speakers in an enclosure?

Hopefully this question can be answered without knowing the specifics of vented or sealed (as I haven't yet decided).
Asked by: DD Warner
Yes, regardless whether it is vented or sealed, everything doubles when you add a second driver.
