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, rubber magnet boot, and gold terminals.

Rated 5 out of 5 by from great full rangeamazing speaker for price, vocals are Cristal clear, great mid-range, i will buy more

Rated 5 out of 5 by from Happy with themMy first ever speaker project is a RockNDock from the Speaker Project gallery.I really surprised how much sound these put out and some decent, punchy bass for their size.

Rated 5 out of 5 by from Clean and BeautifulBig things come in small packages. Thats the first thing that came to mind when I first heard these. Clean detail, no typical muddy midbass these sound fantastic. For a smaller than 4 inch speaker, you'd never be able to tell them apart. They bring a large stage to your home.

Rated 4 out of 5 by from Tried it outThere a directness to the sound that I like. However in my 1.5L test box there are also resonance that are not well controlled. Overall I think I need a better driver for my projects. If anyone has been able to tame single note peaks let me know

Rated 4 out of 5 by from Good fit, good soundI used this item to replace a dead speaker in a 1950s record changer. The biggest issue was with speaker coil load and the physical size of the speaker. I was happy to find a 4 ohm full-range speaker, but size was a concern. When it arrived, it fit well and sounded great. I will definitely keep Dayton in mind for my next restoration.

Rated 5 out of 5 by from Incredible sounding speakers.....i was hesitant at first to buy these speakers but i sure am glad i decided to pull the trigger and get them. I actually use these in my car audio setup in custom built a-pillars and they sound incredible running with my polk audio mm6501s. i've had them now for 8 months and am still blown away at how vocally nice these speakers sound and for the price its a hard speaker to compete with.

Hey There! I have recently purchased these for a "daytons needle" TQWT build. I was hoping to replicate their simple 3 piece crossover/filter, but their component specs are vague. Any recommendation some components. Its just one of these drivers per side.

Asked by: AlethiaSound

I noticed some other folks have a little confusion as to the size of this speaker. Overall outside diameter is smaller than bolt circle diameter?? Shouldn't it be 3.86"?

Asked by: RhythmJunky
Yes the outer diameter is wrong on our website and I will have it fixed.

Asked by: hjay
In order for the crossover not to change you will want to use the RS100-8 instead.

i plan on using two of these in stereo in a single .23 box I did this with two 4inch coaxils but the 200 hz hum is bothersome and I cant get rid of it, it is for tv use only what size port would work for both speakers in your knock down .23 box. thanks

ive been looking into building a portable boombox, for BBQ's or the Beach. i want it portable but with punch and good battery life. I was thinking perhaps a pair of these speaker and and 6 inch subwoofer. can i use a leipei 2020 amp with a 12v 7AH Battery

Asked by: antonio229
Yes this will all work very well together. A similar design has been made using similar components in the RockNDock project which you can see below. This uses the DTA-2 amp module, two of the RS100-4 drivers and a pair of small flange tweeters. It is powered with a 12V SLA type battery.http://www.parts-express.com/project-gallery-speaker-project-rockndock

Will these work well with a passive radiator to produce more bass?

Asked by: wawall
This driver will perform best in a standard vented enclosure of about 0.11 cubic feet with a 1" diameter port that is 4" long for a tuning frequency of 65 Hz.
