Dayton Audio 15" Ultimax Subwoofer and Cabinet Package

Buy this 3.0 cubic foot knock-down cabinet together with the Dayton Audio UM15-22 15" subwoofer (at regular price) and save half off the original price of the cabinet. That's a savings of over $60!

About the Cabinet

This particular cabinet is designed specifically for the Dayton Audio 15" Ultimax subwoofer, but works for any subwoofer with an overall diameter of 15-3/8" or less, and a cutout requirement of 14" or less. For optimum performance with the Ultimax 15" subwoofer, add three pounds of Acousta-Stuf polyfill for a Qtc of 0.707 and an f3 of 35 Hz.

During the CNC manufacturing process, rabbets and dadoes are cut into the back panel for precise panel alignment. A unique two-piece brace adds superior rigidity without affecting the subwoofer's performance. Both side panels feature 3/4" rabbeted extensions with recesses to perfectly install the first piece of the two-part, double thick baffle. Plate amplifier installation is made easy by following the scribed interior guide with a jig saw and by modifying one of the braces.

The end result is a resonance-free, sealed subwoofer cabinet that is purpose-built to extract the best performance from Dayton Audio's 15" Ultimax subwoofer. All that's left to do is finish it to match your décor or paint it to stand out. When your friends ask about it, you get the pleasure of saying, "I built it myself!"

Specifications: • Panel thickness: 3/4", front baffle is 1-1/2" • Panel material: Medium Density Fiberboard (MDF) • Finished net cabinet volume (subtracting the double thick baffle, bracing, and woofer volume): 3.0 cubic feet • External dimensions: 19.25" H x 19.25" W x 20" D • Subwoofer recess: 7/16" • Weight: 52 lbs. • Made in the U.S.A.

About the Subwoofer

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.

Specifications: • Power handling: 800 watts RMS/1,600 watts max • Le: 1.31 mH • Impedance: 4 ohms  (2 ohms/coil) • Re: 3.4 ohms • Frequency range: 15-1,500 Hz • Fs: 19.5 Hz • SPL: 89.5 dB 2.83V/1m • Vas 7.92 cu. ft. • Qms: 2.4 • Qes: 0.59 • Qts: 0.47 • Xmax: 19 mm • Dimensions: Overall diameter: 15.28", Cutout: 13.78", Depth: 7.55". 

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

Dayton Audio 15" Ultimax Subwoofer and Cabinet Package is rated 4.9 out of 5 by 10.
Rated 5 out of 5 by from Everything fits perfectlyWell done cabnet, everything is cut perfectly. Subwoofer hits really hard with my Crown 1100 watt amp, shakes the front door, and moves pictures on the wall. Just about the perfect amount of Bass :)

Rated 5 out of 5 by from Great subwoofer for Home Theater and MusicI ordered the 15" Ultimax Sub and Cabinet package as an upgrade for my home theater. And what an upgrade it is.First things first: The ordering process and support while I was researching this product was top notch. I used the live chat to ask a few questions. The tech that I spoke to had all the answers I needed and made sure that I had a list of everything I needed. My order was placed on a thursday morning the week before Christmas. My packages were delivered on the following Monday, allowing me 3 days to build before Christmas.Unpackaging the components, I noticed how well everything was packed. And the driver is HEAVY. Its a beast. Everything about this driver screams quality. The cabinet pieces are nice solid HDF (maybe MDF), I dont know the difference. But it is 3/4" and everyting fits together with minimal work. I was able to glue and clamp it together in a couple hours and let it sit overnight before finishing it.My home theater room is approximately 16' wide by 24' long. I had been using a Mirage 310 subwoofer (10" 300watt). It was great in my old listening space, but when put into the home theater, it left something to be desired. I now have the Ultimax 15 powered by one channel of a Behringer NU3000. I am soon going to order a second Ultimax 15 and run two of these in my HT.Sound quality: Not only does this configuration produce huge bass, it does so with quality. My goal was clean hard hitting bass for movies and some use for music. I ended up with a subwoofer that produces great sound in movies. But i find myself in the room laying on the couch enjoying music alot more than I used to.I listen to alot of older rock (Pink Floyd, Zepplin, the Who, etc...) But to test the setup, I threw on a couple base heavy tracks from the Beastie Boys. It handled everything with ease and no distortion, even when I turned it up unreasonably loud. Pink Floyd and AC/DC can give the sub a workout, but I wanted to see how musical this would be. I brought up some Yo-Yo Ma, and symphony music. I was amazed at the tone brought to the music. I switched between my old sub and the new one during multiple songs. Not only did I hear notes I never knew were there, I could actually hear vibrato created by the bow on the strings. Simply amazing.I cant say enough about this subwoofer and Parts Express. If you are considering this product, buy it! You wont regret it.

Rated 5 out of 5 by from Better than Epik Empire, very impressed!I never review products, but has been such a good purchase I had to write one.First off the box kit was very well built and is super inert and very solid. It took me about 2 hours to put everything together. Unfortunately I didn't have clamps large enough so used wood glue and screws.Sound: this sub is precise.The Dayton has scary amounts of excursion, this is why it probably goes a lot lower than my Epik. I can continually get 12hz tones that shake everything in my home theater room. the mid bass is well rounded too, with no bloating. The only area that the Epik does slightly better in is the bass between 80-120 hz but that range of bass doesn't really matter to me since I have my cutoff frequency at 80 hzOverall I am astonished at the level of quality that Dayton has put into this driver. I am equally as impressed with Parts express and their level of service and price offering. Cant believe this came with free shipping !!If you are looking for a serious home theater sub and have never done a DIY project don't be afraid. This project is easy and the payoff is huge.Five stars !

Rated 5 out of 5 by from Excellent valueI purchased this combination a few weeks back. Delivery was prompt. The cabinet was very easy to assemble with a few bar clamps and wood glue. The sub itself fits the cutout perfectly. I do plan on adding a little polyfill when I put the finish laminate on the cabinet, but the response is great. I paired the unit with the SA-1000 Dayton subwoofer amp. They work great together. I was planning eventually having a second but have absolutely no need now after measuring the response from the single cabinet. I am using this for the media room in my basement, and the effect it adds is subtle (not boomy) and blends nicely with my soundstage. In the room over the basement you would think the walls are flexing. Superior performance.

Rated 5 out of 5 by from Yes!Yes! That's all I can say about this thing. I just received this behemoth a few weeks ago, and other than weighing 30,000 pounds, it is an amazing sub. Simple to hook up. I have (2) of the Ultimax 15" subs and 3cu/ft box combo's, and I currently only have one hooked up. I could not imaging having both of them hooked up in the same room. I have this powered with the Dayton 1000w Rack mountable amplifier, and one of them in a 3cu/ft box has no problem putting out 20hz with authority and shaking pictures off the walls!

Rated 5 out of 5 by from So smooth and powerfulI bought this and absolutely love it! The response is so smooth! This thing moves quite a bit a air and has some insane excursion. I'm thinking of adding some passive radiaters but for a sealed system it puts out.

Dayton Audio 15" Ultimax Subwoofer and Cabinet Package

I already have a Dayton HPSA1000-R amp.  Can I drive this sub with the voice coils in parallel with this amp?  

Asked by: Doc H

Would like to use this kit for a garage woofer. 2 car garage, open beam ceiling. Mix of HT and music. Prefer it sound best with music. Will this kit in conjunction with an 500 watt plate amp do the trick?

Asked by: Javi
This will work but in an area that large you will have to try different placement options in order to get the best room coverage.

Would a  SPA500 be a good choice for this combo? 

Asked by: Patrick1229
I would recommend the SPA1000 in order to get the most from this woofer.

I'm wanting to replace the driver in my Sub. with a  Ultimax Series DVC subwoofer. My box has a max internal vol. of 2.843 sq ft. Would my box be to small for the 15" or to large for the 12" ? Witch one would you recommend for home Audio and HT.

Asked by: J Hull
The 12" would work very well in that volume as long as it is sealed. It would be on the small side for the 15".

Besides the spa1000, what other plate amps would be a good match for this combination....Will be used for HT mostly.

Asked by: Maestro7954
Too many to mention here. Any amplifier that will produce 500-1000 watts RMS into 4 ohms will work for this subwoofer. The Behringer NU1000DSP would be a popular choice.

Will the Dayton Audio SPA1000 fit in the back of this box? 

Asked by: maestro7954
Yes that amp will fit.
