Product Details

Dayton Audio UM10-22 10" Ultimax DVC Subwoofer 2 ohms Per Coil

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. 

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.

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 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.

A knock-down 1.25 cubic foot subwoofer cabinet built specifically for the 10" Ultimax is available here. Save 50% off the price of the cabinet when you buy the cabinet and Ultimax subwoofer (at regular price) together in this package only.

Cabinet recommendations: 
• Sealed 0.63 cubic ft. (net internal), f3 of 45 Hz with a 0.707 Qtc alignment
• Vented 1.75 cubic ft. (net internal, not including driver or port volume) tuned to 25 Hz with a 10" wide by 1" high slot port that is 24" long, which yields an f3 of 23 Hz

Note: All parameters derived with voice coils wired in series.

Dayton Audio UM10-22 10" Ultimax DVC Subwoofer 2 ohms Per Coil
Dayton Audio UM10-22 10" Ultimax DVC Subwoofer 2 ohms Per Coil is rated 4.2857 out of 5 by 14.
Rated 2 out of 5 by from RattlesI bought this driver with the intention of getting a small driver that packs a big punch. The construction is top notch and it definitely looks the part. Unfortunately, it has had a mechanical rattle from the start, even at low volumes. At first, I thought that perhaps it needed to be broken in, but there has been no change.It looks like I'm going to be removing this subwoofer and replacing it with something more reliable. It is a shame, because it certainly looks indestructible. I just wish I didn't wait so long to realize it. Now I'm stuck with it!

Rated 5 out of 5 by from Just SUPERBIn comparison with other and more expensive subs, this sub destroys all in its path. End of story people !!!

Rated 5 out of 5 by from GReAT SUB!Have had many subs, n until this sub, have not been fully satisfied. This sub delivers the clearest of the low frequencies in a tone that is unmatched by any sub I have owned to this day. I would recommened this to anyone adding to your home setup

Rated 4 out of 5 by from Surprising output from a small enclosureOverall: Excellent sub for the price, does a great job of replacing larger, dual-sub systems when you want to reclaim some space. it's power-hungry with good extension but can be a little boomy, but I think that's more my application than the sub itself.Details.First and foremost, I am using this sub in a VERY non-ideal situation. It's running on 480 watts in an enclosure that's probably about 6.2 cu ft (give or take .2) after driver displacement in the back of my XJ.The sub manages to dig surprisingly deep and gets quite loud with this setup. Definitely not audiophile-quality, but very good. I would say it compares favorably in both response range and output (though it does have limits) to the two infinity 12's I replaced with it. The sound comes of a bit boomy, and it does roll off higher than I'd like, but listening to it I suspect both of these are due to the undersized enclosure. I have no complaints at all listening to hip-hop, dubstep or pop. The boominess is a weakness on the ultra-fast kickdrums in metal, or some of the more detailed bass notes in Jazz or Soft rock, but definitely listenable and more pleasant than missing much of it entirely, as I was without a sub. It's still breaking in, I suspect some of that will improve as it loosens up. I'm also hoping the extra cone control from the small, well-sealed chamber will prevent the spider from coming loose as it has for some other users.

Rated 5 out of 5 by from great subwoofer!this guy is very well made, I didn't have some of the qc issues some others have said they have had. I purchased the box combo you can get with this sub and once together is is a beast. I lined the box with acoustic foam and 1lb. of filling. I found that with the filling the bass more defined and deeper. As far as accuracy I would say it is very accurate. I own a reference 10 and the difference between the two is this. The reference is clean and accurate while the ultimax is stout and has more authority with the bass. cant go wrong with this!!

Rated 4 out of 5 by from A lot of displacement for the money.There is a QC issue on the first batch of these drivers it would seem. Most are fine but there are a few duds with possible misalignment and/or an improperly glued lower spider which can slap and scrape about. However, upon discovering a problem with my driver PE was prompt to replace it at no expense to me. The exchange was smooth and fast. I'm dropping a star for the minor inconvenience but otherwise I am very happy with the replacement driver and the way in which PE handled the exchange.----I'm going to try this out in a horn loaded enclosure. Physically I think a "super" sub like this could be a very good candidate for maximizing SPL/bandwidth per cubic foot in bass horns.I really like the way the UM series of drivers looks aesthetically so I couldn't resist giving this a try. If I run into problems in the horn I can't fault the driver as this is very experimental at this stage. My thought process however, is that the cone of the UM10 is VERY rigid (low Vas), and the double spider should help maintain alignment with uneven pressure across the cone from the constricted horn entry area. crossing fingers ;)Still a lot of work to "finish" the sub (both internal and external) but I took the opportunity to hook things up and see if everything is working properly. The replacement driver is dead-nuts quiet in operation and based on initial testing must be a very low distortion driver.Simulation suggests I should be able to achieve ~125dB or better in-room from ~30-80hz from the single 10" with a 1KW amp.

Dayton Audio UM10-22 10" Ultimax DVC Subwoofer 2 ohms Per Coil

Is this a good sub for music and HT in a sealed enclosure about 1.3 cu ft. and a bash 500.

Asked by: Ad123
This driver should do fine in that setup. It is a lower Qtc than a traditional ".707" alignment but still models very well. Some prefer a lower Q type design like this.

Need help selecting the proper driver for a home theater subwoofer. The box is approximately 1 cu. ft., will be driven with a BASH300 amp. Is this the best choice or would the RS265HO-4 or TS280D-4 be a better choice.

Asked by: KarlS
In my opinion the Ultimax will be the best of both worlds in that volume sealed.

I'm looking to invest in the low end of my audio experience... I'm curious as to whether 2x 10" Dayton UM subs will compare to one 15" Dayton UM. I listen to more music than movies, currently using the tritrix TL speakers as mains in a stereo config

Asked by: OscarMartin88
Two subs will give you better coverage in the room but a single 15 will play lower and louder. You may consider a pair of the 12's instead which will play just as low and loud as a 15 but still give you better overall coverage in the room.

Can this sub be used free air?  I'm interested in mounting it in a rear deck using the trunk space as the box.

Asked by: ajones51
This will work well in a free air application.

What would the effects be if I placed the speaker in a 3.5 cubic foot vented box? It is specified for a 1.25 cubic foot box.

Asked by: Toml
Putting this woofer in a box that large would be considered an EBS design. It will help with a lower tuning frequency and shorter port but it will be limited on excursion, overall output and how high it can be crossed. This type of design works well for application specific scenarios when you want a low tune that doesn't need to be crossed very high (say, 40-50 Hz). Depending on what this will be used for, you may be farther ahead sealing off the port and throwing the 15" Ultimax in there.

Ultimax 10 vs. JL 10W6, Part Two

Matt P, thanks for the quick response! I have bragged previously to my friends about the helpfulness of Parts Express personnel, but will do so all the more now.If I were to adjust the ports, how big/what dimensions would they need to be to keep similar tuning with the Ultimax's, and avoid wind noise?
Asked by: John L
The smallest diameter I would use is 4" and flared, but in order to get the same tuning frequency it would need to be about 30" long. A slot port wouldn't help either, it would need to be 1.5" x 11" x 45" to tune to 25 Hz.
