Dayton Audio RS100-8 4" Reference Full-Range Driver
Dayton Audio RS100-8 4" Reference Full-Range Driver is rated 4.3846 out of 5 by 13.
Rated 5 out of 5 by from Great little wooftweeter!!I was searching the internet for a project to do for some desktop PC speakers and I ran into a review on some Ancient Audio speakers. The reviewer raved about the sound from the single driver and he actually took them apart and I noticed that it was this little guy in these extremely expensive desktop speakers. I'm no audio engineer so I had to use Thiele parameters and stick to them as I didn't want to be tweaking for months to get good sound. I put these in some .26 cubic ft boxes with a 1" port that is .75" deep (see pic) . I then coupled them to an old technic receiver along with an 8" sub and a sound blaster xifi external sound card via optical cable. You need a decent soundcard or DAC IMHO to get a good clean signal. A better amp wouldn't have hurt but I'm cheap. Finished the cabinets off in birch veneer and mounted them on cedar post stands. The wife says they don't match but.. whatever!These things sound amazing especially after adding some pillow stuffing to smooth them out a bit. The box is tuned to 87Hz so that's what I set the cuttoff at on the Creative software since there is no crossover at all in the box (straight to the amp). The room they're in is a dedicated office/media room that's about 11'x11' so these really work well in that small of a space. Any larger room wouldn't work well for these little buggers. Paul Simon played on 96/24 .flac format sounds perfect. These things really shine on vocals, wind instruments and guitar. Don't expect the midbass range to blow your underwear off though. The 8" sub is crossed at 100Hz to help out a bit in that category. All-in-all I'm very satisfied with these as I only have around $70 tied up in the pair's build. I don't think they'll beat Ancient Audios use but it's nice to know I'm using the same driver that those guys are.

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. :

Dayton Audio RS100-8 4" Reference Full-Range Driver

I would like to use 4 of these drivers in a single enclosure. what is the enclosure and port size to achieve the best bass?

Asked by: chris 13
I would build 10"X 10" X 5" with a bottom vent of 2-1/4" X 8-1/4" across the bottom.

Work as mid-range with other specs below?

I'm looking at my first 3 way build (trying to keep things as simple as possible). DC250 10inch for woofer and DC28F as tweeter. Crossover at 500 and 4000. Would this speaker work as the mid-range? I worry about sensitivity...Or maybe I'm wrong on all of this and I have no idea what I am talking about. Any help would be appreciated!
Asked by: youngaa1
You could use this driver for a mid-range, but i agree that since the sensitivity is lower than the other speakers, it could lead to somewhat recessed mid's, however, that could be addressed with the crossover. I suggest looking into using the Parts Express Techtalk forums for more specific recommendations.

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.

Power handling as a midrange?

What can I expect for power handling from the RS100 if it's high passed somewhere around 150-200 Hz? At these frequencies excursion shouldn't be a concern, but cone control and thermal limit will be. Anyone with experience in this area? Drivers would be mounted in a small stuffed sealed chamber.
Asked by: superspeeder
For your frequency range, I wouldn't push the speaker any more than the RMS 30 watts.

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
Will definetly do the work with that crossover in mind, I would try to fill the 0.3cu-ft cabinet with as much as half a pound of polyester fiber or Acoustastuff that PE sells... Just for that 200Hz humm resonance that small boxes produce...:)

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.
