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 together in this package.

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.

Suspension acceptable for down firing application?

Is the suspension suitable for a down firing application? Will it "sag" over time?Thanks in advance.
Asked by: Troystg
any speaker will work in a down-firing use, just be careful that your box/cabinet is high enough so the cone/surround dont hit the floor.

Comparison to Titanic 10" or RSS265HF-4

I'm trying to select a new 10" sub for my car. I have a just over .6 cu. ft. sealed enclosure with plenty of depth and my sub amp bridges to provide 480W RMSx1 @ 4ohm. I'm nervous about choosing between this, the Titanic MKIII 10" 4-ohm and the 10" Dayton HF subwoofer. Does anyone have direct experience with any or all of these woofers in a similar set up?Ideally the sub would be for music only, handling from 120hz down to a subsonic filter that I'd probably set between 20 and 30hz depending on useful output I see from the box. I listen to all varieties so I need something that balances neutral sound with output.Thanks for your input!
Asked by: Azuth
Consider the RSS265HO-4. It's a better match to that box size and amplification at a lower price. With either the titanic or the UM10 you would be amplification limited rather than displacement limited, which isn't necessarily a bad thing but it would be some wasted overhang that you are never going to tap into. The RSS265HF is only really going to produce a higher "fidelity" performance than the HO when compared in a box that properly complements the different driver characteristics. Of all the driver options including the HO, I believe the HO would deliver the lowest distortion performance in that box volume within the envelope of the amplification provided.

Sealed vs Vented

With Parts Express enclosure volume recommendations, what is the frequency response to be expected from a sealed vs vented box? Also, would anyone recommend low frequency "bass-boost" amplifier technology with either enclosure design for this particular sub? This will be used in a home theater.
Asked by: Leroy
i would personally recommend keeping these sealed in 1-1.2 cubic feet per woofer. This will allow ample headroom for EQing and plenty of output. I just built a pair for my HT and with no EQ I am getting response into the upper 20's very easily. Vented will likely go lower although the enclosure size goes up substantially for a decent response.

downfiring clearance

How much clearance above the floor does this driver need for a downfiring enclosure? Does it matter if it fires into carpet vs something harder?
Asked by: darrellh44
I would give this driver at least 4" of downfiring clearance. The surround sticks out over 1-1/4" alone.

Sealed Volume, Driver Volume

I have used a few different calculators, and all of them recommend a sealed volume of about 0.9 cubic feet with f3 of 40.3 hz (Qtc 0.7), but Dayton seems to recommend much smaller. Any idea why this is?Also, I am trying to estimate the driver volume, and it looks like it is about 0.05 cubic feet for just the magnet, so maybe a little more?This makes me think it should fit nicely into a 1.0 cubic foot box, does this sound good?
Asked by: FocalX100
Yes these work very well in 1 cubic foot sealed. I build a pair with an internal volume of 1.04 cubic feet and they are excellent subwoofers.
