Dayton Audio RS100-8 4" Reference Full-Range Driver is rated 4.4667 out of 5 by 15.
Rated 5 out of 5 by from Low expectations but boy was I suprised! Niceafter building with the small enclosure these sounded great.

Rated 5 out of 5 by from Okay, I admit I bought it for the looks.I decided I wanted to build a simple, straightforward project for a friend who's an avid bow hunter. This has the perfect visual appeal I was looking for and sounds very good for a full range driver to boot. The photos give you an idea of how it fits into the archery theme. There's just enough bass to get the job done paired with the Lepai amp.

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.

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

I see the mounting hole diameter is 4.3mm, but what is the diameter of the recess?  Will M5 cap head screws clear the recess or should I stick with M4?

Asked by: heedong
The diameter of the recessed opening is 6.8mm.

I want to use these in a 2way tower where they're fed full range signal in their enclosure volume and the other 2 drivers (6" and 1") are fed by a crossover. Is this uncommon or not recommended? 

Asked by: MikeyMike
I would not recommend running this full range if you intend on using it as a midrange. You will want to use a high pass filter to block low frequencies at the very least, and to prevent phase integration issues a low pass is also recommended. So a full 3 way crossover will yield the best results.

Currently have these in a small ported enclosure and sounds good.  But noticing that the lower frequencies are quieter. Thinking of adding a Zobel network.  I believe a 10uf cap with 8ohm resistor would work.  Don't have way to test, just going by ear.

How would this work as a column array for pro audio applications?  I was considering the FitalPro 3FE35 which are used in Peavy column arrays but these look far superior.   I was looking to put 8-12 per cabinet.  Suggestions?

I am using this midrange with a HiVi M8a and a DC28F, in a 1.75 ft^3 box. I am using a 3-way crossover @500hz/3500hz.  So to isolate the mid from the woofer, can I use a .035 ft^3 MDF box for the mid? Or how about a 4" PVC endcap? Does it need more space?

Asked by: JazzC
As it will playing midrange frequencies, size is not an issue.

I am considering using 2 of these in a single enclosure powered by a t class mini amp to become a boom box type item.  Can this be done with the speakers wired directly to the amp without using some type of crossover gizmo?  My apologies for my ignorance.

Asked by: edwinhen
Yes these can be used full range without a crossover in an application such as a boom box.
