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.

Dayton Audio RS100-4 4" Reference Full-Range Driver 4 Ohm is rated 4.4138 out of 5 by 29.
Rated 4 out of 5 by from ArticulateMy son called it the best-sounding car stereo system he's ever heard in his 22 years of life! I like the minimalist idea of having one driver to reproduce everything but the low end. Sparkle is missing from the high end.

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.

On your website, the cut-out size for the 4-ohm version of this speaker is stated to be 2.73", so I bought a 2.75" hole saw. Then I looked at the cutout diameter specified for the 8-ohm version, and it is stated to be 3.06". Please correct this error.

I will have the site updated.

What size box and vent should I use for a two speaker setup? How would I adjust the box and vent size if I added a 1inch tweeter?

Asked by: desain2
For a two-speaker system, each enclosure should be the same size as the recommended enclosure volume, and should have the same tuning frequency. If you mean to use two woofers per speaker, then you will need to double the enclosure volume, but use the same tuning frequency. Adding a tweeter will not affect the box size, as long as you adjust driver placement to provide enough room on the front of the cabinet to mount the woofer and the tweeter close together.

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.
