Going by the measurements, it should fit in the same flat pack as the 3 cuft model made for the 15" Dayton RS model.

Remember guys, Lilmike said this driver would be good in the f20. So anyone considering a build should snap this up today!

How does this driver compare to the HO15 and the HF15? What about the Titanic Mkiii 15"? I need to pick up a few more subs, and this seems like a good deal, I just want to make sure that I am not better off going with one of the other HF/HO models.

Handles more power than the HF, plays lower than the HO. Is very similar to the Titanic.

HF handles about 350 Watts, Ultimax 500 Watts, HO 600 Watts.

F3 in a sealed box (approximate) HF- 32 HO- 44 Ultimax- 29

Box size approximate:
HO 2 cubes Ultimax 4 cubes HF 3.5 cubes

They say the Ultimax 15 likes a 3.1 cubic foot box, but that seems to put the Enclosure Q around 0.9, which is a little high.

Of these three drivers, the ultimax appears to be the best for low bass, in a sealed box, with the caveat being it likes big boxes and doesn't need a ton of power, but is also not the most efficient.

It also has cleaner top end response then the Titanic. Le 3.11 vs 1.31

WOW, I just modeled the Ultimax and the HF in 4.42 ported boxes with a 21.4Hz port with 775w and they model EXACTLY the same except the HF blows past it's xmax while the Ultimax still has some on the table. I just thought that I'd put that on the table as it was kinda odd to me.

FYI, I already have this box which is why I modeled it. I know that it's not the ideal box but I wanted to see how they would perform in it.

It's pretty nice. I think of it as the higher output version of the 15HF that we all wanted. It will require semi-large sized cabs (for a 15") but the extension is smooth and deep. I'd opt for this one now over the 15HF.

So if this needs such a large box, why wouldn't you just put the Dayton 18" in there instead? They both want about 4cuft sealed it seems

Serious question lol. If someone could model the 2 that'd be great!

I'm thinking about going the DIY route instead of picking up something like the Outlaw LFM-1ex, Epik Empire, SVS pb-12nsd, etc. I'd think the 18" Dayton sealed would be better in most aspects

Beeeecause this is currently about $170 and the Dayton 18HO is $250. That's reason enough for some people. wink.gif


Oh? Did someone say comparison model? I can do that! Back in a flash!

Yeah good point lol. Pretty bad I didn't even think about that. I thought about saying it's the same price as the 18"HO for you AK people, but you'd have to pay shipping on that sucker too! That sucks eek.gif

So here is a comparison of the new Ultimax 15 versus the 18HO each in 4cuft and with 600w per driver. The T/S specs used were provided from PE/Dayton.

Just from a quick assessment, that appears to perform pretty close to the HO. Might be a great alternative option for many looking for a budget build.

That doesn't look like too much of a difference. Around 2-3db at most. All else is equal but price....looks like you can save $80-100 and go this route or spend that and get a few extra db.

Definitely a great choice for the $$$ spent and literally only 2-3DB from the 18 across the board. Just recommended this to a buddy with a new theater project and he picked it up. We'll be building soon!!

I've been trying to talk him into the 2nd driver right off the bat. biggrin.gif

Except the Ultimax exceeds XMAX at 600W. It's got less cone area and is less sensitive.

When we designed the Ultimax subwoofers, we were aiming for excellent performance in a sealed box. Performance in a vented box took a back seat to making sure the sealed alignment performance was competitive with anything out there. This isn't to say that you "can't" do a good vented enclosure alignment with them, but they really shine in sealed boxes, whether for home theater or car audio. (IB use isn't recommended without close attention to excursion -- we offer a purpose-built driver for that.)

Using them sealed also gets rid of the question of how to properly port them for maximum air movement. A pair of the PR-15 passive radiators from AE Speakers are just barely enough to cope with a single 12" Ultimax driver. The Ultimax have Klippel-verified 23mm Xmax (19mm is the coil-length-derived figure), but they have even more mechanical excursion, to help them stand up to abuse, and it's at those levels that even the pair of 15" high-excursion PRs won't be able to keep up with the Ultimax 12" model.

We recommend the SPA500 plate amplifier for the 10" model, and the SPA1000 plate or SA1000 rack amp for the 12" models. Be careful to wire the coils in series to achieve the correct impedance: (Amp +)======(Coil1 +) (Coil1 -)======(Coil2 +) (Coil2 -)======(Amp -)

Happy bass-ing.

Would someone be kind enough to run a quick sim on the power required for this thing to hit xmax at 20 or 30hz in an infinite baffle arrangement?

True to form I have got myself in another subwoofer design mess and need to pick up the smallest amplifier wattage that will drive the heck out of it in an infinite baffle (sort of... more like 17 cu ft leaky box). I'm hoping ~500 watts is sufficient. I'm away from my computer that has modeling software on it for a couple days and wanted to buy something, oh, say, tonight or tomorrow. lol

Thanks,
Chris

500 watts in an IB will hit 23mm xmax at 23 hz. By 10 hz you would be at 42mm. I hope you have some kind of high pass filter

Perfect. Thank you very much for your time. Seems like if I go with the smaller amp (~500 watts) it'll be more than sufficient. I do have a high pass filter, adjustable at that.

Thanks again,
