Product Details

Dayton Audio UM15-22 15" Ultimax DVC Subwoofer 2 ohms Per Coil

If you want outrageous amounts of bass, you gotta move some air

The Ultimax Series of dual voice coil subwoofers, from Dayton Audio, are not for the faint of heart. Built using the latest in subwoofer technology, Ultimax subwoofers are the pinnacle of low frequency driver design. An Ultimax subwoofer tests the strength of your foundation with fast, articulate, gut-wrenching bass.


The versatility you need for mobile, home, or pro subwoofer excellence

Dual 2 ohm voice coils allow for stereo 2 ohm and mono 1 ohm wiring configurations when connecting to high current car audio and professional audio amplifiers to extract maximum power. For home audio applications, simply wire the voice coils in series for a benign 4 ohm load for greater amplifier compatibility.


Built to produce massive low frequency output and keep on doing it

To improve power handling, increase thermal management, and reduce power compression, Dayton Audio designed the Ultimax Series with large black anodized formers and vented pole pieces, under-spider ventilation, and two-layer copper voice coils.

Over 1-1/2" of travel (3/4" Xmax) is kept completely linear through the use of dual spiders that also limit distortion and rocking modes. "Tall-boy" rubber surrounds with integrated gaskets maintain driver surface area during extreme excursion moments. Thick, one-piece Nomex honeycomb covered cones are covered with woven, heavy-duty glass fibers creating ultra-still cones that resist deformation.


A strong motor takes you to wherever you want to be

A large copper sleeve and copper pole cap in the motor reduce energy storage from inductance, with the side benefit of lowering distortion for "faster" response. Large dual-stacked, high-energy magnets handle the heavy lifting and bring Qts down to a level where Ultimax subwoofers can be used in vented or sealed cabinets and enclosures.





Save time, effort, and money! Combine an Ultimax subwoofer and a knockdown enclosure!

A knock-down 3.0 cubic foot subwoofer cabinet built specifically for the Dayton Audio Ultimax 15" subwoofer is available here. Save over $30 off the price of the cabinet when you buy the cabinet and UM15-22 subwoofer (at regular price) together in this package only.

Cabinet recommendations:
• Sealed 3.1 cubic ft. (net internal) with 3 lbs. of Acousta-Stuf polyfill, f3 of 35 Hz with a 0.707 Qtc alignment
• Vented 6.0 cubic ft. (net internal, not including driver or port volume) with 6 lbs. of Acousta-Stuf tuned to 18 Hz with two 4" diameter by 26" long flared ports for an f3 of 22 Hz. Larger cabinets and lower tuning frequencies are possible.

Dayton Audio UM15-22 15" Ultimax DVC Subwoofer 2 ohms Per Coil
Dayton Audio UM15-22 15" Ultimax DVC Subwoofer 2 ohms Per Coil is rated 5.0 out of 5 by 31.
Rated 5 out of 5 by from Fantastic SubwooferI've owned dozens of subwoofers over the last 25 years and this one is fantastic! It strikes a great balance of balls to the wall output and good sound quality. I built the minimum 3cf sealed enclosure stuffed with 3 lbs of fill and it's really good. I wanted to keep it as discrete as possible. I am powering it with the Crown XLS2502 coming off of a ROLLS MB15b Promatch converter from RCA to XLR. The Rolls was ESSENTIAL to get this amp to perform with my Marantz SR7002 receiver. I have to almost max the gain on the Rolls to get a clip light. Once the gain was just under clip, I leave the gain on the 2502 to just over a quarter for FANTASTIC output in my 16x20 living room with an open wall on one side. I'm convinced I could easily run a pair of these off the XLS if I could get the right voicecoil config.

Rated 5 out of 5 by from Amazing sub for the priceI bought one of these a while ago and finally finished building the box for it. I went with the suggested 6 cu ft. net internal with 2 4" dia x 26" long ports, and it literally blows me away...The box is 3/4" MDF with a total internal volume of 7 cu ft. With the port and driver volume, it is closer to 6 cu ft. It's also around 120lbs with the driver installed.

Rated 5 out of 5 by from BOOM BOOM!!!!I just wire my dual subs and all I can say is WOW! I was running 2 Pioneer TS- w384dvc subs but these are much stronger subs by far. Thanks Parts Express and Thanks Dayton Audio for producing such a wonderfully high powered sub.

Rated 5 out of 5 by from Never find another Sub like this for the priceBoom. It performs as specified. The carbon fiber "look" and no dust cap is very cool. Rugged construction looks like it will hold up. The only thing I was not thrilled about, was the fact it was made in China, unlike other Dayton subs I own, proudly made in USA. Another observation is that I don't think the electrical matches the mechanical potential. It appears to clip long before it ever hits max excursion. Definitely not a power supply issue from a 6000W amp. This could be my enclosure, or it just may need more break in time. Don't let that discourage you though. It will punch you in the face when you crank it up. Positively, I do not have to worry about over driving. I can lower the subsonic filter and really feel the lows. It does produce sound at 30hz. You would probably need to customize your enclosure to really hear it, as opposed to mainly just feeling it. I'm speculating a ported downfire would achieve this. I'm using a custom folded horn and getting 145db @ 3ft. @ 40hz. Sadly, this is only equivalent to the 12" Titanic I own, which for some reason was discontinued.

Rated 5 out of 5 by from UM15-22 Running "Free-Air" in a Infinity G35I installed a single UM15 in a free air application in a customer's Infinity G35 running off of an Alpine 1000 watt amp. The sub fires through the trunk access hole where the rear seat arm rest is. The Alpine is not stable at 1 ohm, so running at 4 ohm at 500-600ish watts. I was able to tie directly into the factory Bose sub for the signal line without using a signal converter which was nice. The sub is very clean, very smooth, and gets down and dirty on the low end. The customer is super happy and was able to keep almost their entire trunk space, which was a design requirement. He loves rap, hip hop, some techno and has told me that it plays it all effortlessly. Couldn't be happier and will definitely be using more of these great drivers.

Rated 5 out of 5 by from In a league all it's own.I purchased this sub with the idea of putting it in the box I made its about 5.0ft to go along with the Crown XLS 2002, what can I say this sub sounds fantastic, it gets low and really handles with detail.Watching "Pacific Rim" was awesome the giant Kaijus and Jaegers really come alive made me almost jump out of my seat,and watching the "Jurassic Park" movies when the T-REX started growling it sounded so real I am very happy with this sub.Thank you Dayton Audio.

Dayton Audio UM15-22 15" Ultimax DVC Subwoofer 2 ohms Per Coil

I know the flat pack for these are 3cu ft. I was thinking of making my own sealed box trying to achieve 4cu ft. What size do you suggest the box to be? and how much polyfil, if any, should I put? Thanks

Asked by: Kailuastyle
This woofer will work fine in 4 cubic feet sealed. You won't need much in terms of fill, maybe just a pound or so.

I bought one about 2 years ago. I made a ported enclosure. I have decided to go with 2 in a sealed enclosure. Should I buy 2 new woofers or will it be of using one used and one new?

Asked by: bonotech25
There have not been any changes to this driver that should have nay effect on sound so i do not see any problem with using two that are different age together.

Are wires included?  If not, are there any recommended wires to buy?

Asked by: Ultim8dude
This does not come with wiring, but any speaker wire that is 16 gauge or larger would work well in this application.

I originally decided on two ported UM12-22's for home theater use. I'm now considering using two UM15-22's or two UM18-22's in sealed enclosures instead. For home theater what would you recommend? Would a NU3000DSP be sufficient for the bigger speakers?

Asked by: AaronB
I personally prefer larger drivers when possible. The extra cone area really does make the lower bass more effortless. I think the i nuke 3000 would work well with either the 15 or 18. That has been a very popular setup.

Why are there two different volume sizes gives in the description (3.1) and specs (3.98) cubic feet for a sealed system? thanks

Asked by: bob_m
I think the smaller of the two takes the driver and fill into account and the 3.98 is gross box volume without anything in it.

I'm looking for 2) 15" drivers for a face to face isobaric of 3.22cuft internal. Box is sealed with 1.5" thickness walls. Drivers separated by 1.5" baffle.

I'm not sure what your question is.
