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, 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.

I WOULD like TO USE THIS SPEAKER TO REPLACE MY N24 JBL 4" . IT IS 8 OHM total CAN I USE THE SAME CROSE OVER AS THE 8 OHM /

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

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.
