Dayton Audio 12" Ultimax Subwoofer and Cabinet Bundle

Buy this 2.0 cubic foot knock-down cabinet together with the Dayton Audio UM12-22 12" Ultimax subwoofer (at regular price) and save half off the original price of the cabinet. That's a savings of over $50!

About the Cabinet

This particular cabinet is designed specifically for the Dayton Audio 12" Ultimax subwoofer, but works for any subwoofer with an overall diameter of 12-3/8" or less, and a cutout requirement of 11-1/8" or less. For optimum performance with the Ultimax 12" subwoofer, add one pound of Acousta-Stuf polyfill for a Qtc of 0.707 and an f3 of 36 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.

The end result is a resonance-free, sealed subwoofer cabinet that is purpose-built to extract the best performance from Dayton Audio's 12" 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 subwoofer volume): 2.0 cubic feet • External dimensions: 19" H x 16" W x 20" D • Subwoofer recess: 1/2" • Weight: 41 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: 600 watts RMS/1,200 watts max • Le: 1.22 mH • Impedance: 4 ohms  (2 ohms/coil) • Re: 3.3 ohms • Frequency range: 20-1,000 Hz • Fs: 24.9 Hz • SPL: 87.7 dB 2.83V/1m • Vas: 2.53 cu. ft. • Qms: 3.45 • Qes: 0.71 • Qts: 0.59 • Xmax: 19 mm • Dimensions: Overall diameter: 12-1/4", Cutout: 11-1/4", Depth: 6-1/2".

Dayton Audio 12" Ultimax Subwoofer and Cabinet Bundle
Dayton Audio 12" Ultimax Subwoofer and Cabinet Bundle is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Awesome!The kit is super easy to build and pieces fit together like a glove. I used Titebond 2 to glue it together with light clamping pressure. I finished it off with green croc vinyl (loctite adhesive spray) and bed liner spray on the front. I'm powering two of these with a Berringer iNuke 3000DSP. They sound awesome!

Could I run this as a 2 ohm sub using only 1 VC? I have a 400w RMS mono amp into 2 ohms. It is only 240w into 4 ohms.

Asked by: rigormortus
I would not recommend using a single coil. Doing that will not allow the speakers motor to work to full capacity, and it will drastically change the TS parameters, changing the cabinet needs for the driver.

This sub will be used outdoors, for an amp I can use either a plate amp of a rack amp such as the Dayton Audio SA1000 Subwoofer Amp fired from a Sonos Connect:Amp sub output (amps would be mounted indoors). Is either amp style preferable?

Asked by: Big Vinegar
The SA1000 with work fine for this subwoofer. The rack mount will probably be more practical for this application if the amp will be separate from the subwoofer.

Wanted to purchase this sub and use for an automotive application. What is recommended to be the best suited amplifier for this type of application

Asked by: newguy97
There are many options. I would recommend no less than 500 watts RMS, 600-800 would be best. Any mono amp we offer that is rated for this output into 4 ohms will work with this woofer.

I was thinking of getting this and was going to get the Yung 500 watt amp because of the sale and cannot decide on the one with boost or the one without, which one of these would be better for this and why?  Thanks 

Asked by: The Shwortz
We generally recommend the boosted amplifiers for sealed enclosures to help extend the low end roll off. If the sub will be used to home theater, this is recommended. If it will be mostly music, the boost isn't necessarily recommended.

What is the frequency response with typical room gain of this kit?  Do you have any graphs of what this kit is capable of?  Can it do 20hz reasonably loud?  Lower than 20hz?  

Asked by: Tbus
Most rooms will have a bump in the response between 40-60 Hz. If you can bring this bump down, this will reach 20 Hz around 3-5 dB down assuming proper placement in the room.

What mounting hardware would you recommend with this? the 10-32?

Asked by: johnnydrama
Yes the 10-32 will work well with this kit.
