NEW 15" Max-x MX15 Subwoofer Review compared to the Ultimax 15

15" Max-X Subwoofer mx15-22: bit.ly/mx1522

Any prayer of MX15 performing well in a 2.6CF box? I have size constraints in my project, it's for mobile DJing. Put another way....what part's express 15" (seeing 4ohm load, probably as series wired DVC 2ohm VCs) will perform best in a 2.6CF ported box?

Looks like money well spent on parts express's side. I just wish they had some better box kits as most of their boxes are small sealed cubes and not ported boxes. I think they could make a dual port maybe 6 cubic foot box with some bracing that came with adjustable length ports and that would work for various drivers since you can adjust the length depending on the tuning frequency. GSG has some nice pre-built boxes though.

How well do the dayton 15s do in the higher end, like 30 to 40? I love my deep bass but i dont want to have to compensate with another, maybe smaller, subwoofer for the rest of my music. This would be a car application

It's a lot prettier of a curve when tuned to 15Hz when compared to the Ultimax, or even the SI SQL-15.

did you ever build a box? would love to have seen it.

Using the 5.3 cu ft enclosure tuned to 22 hz, would I need one or two 4 inch diameter round ports and how long should they be? I can't make any sense of your screen it says 2 x 15 inch which must be a slot vent or something. I tried several online calculators none make any sense to me. thanks!

I'd wager Dayton went with a steel basket for marketing & product range considerations. I'm thinking that when this driver was on the drawing board (figuratively), the design engineer envisaged it having a cast aluminium (yeah I'm a Brit) basket. But when senior marketing guys got their hands on it they realised that with a cast basket it would sit too close to both the Ultimax and the Reference drivers. So this is the result and, if I'm honest, it's still a close competitor to those other options. Don't get me wrong, it does look like a nice driver and it will be a consideration next time I build a subwoofer enclosure. But I'd have been more interested if Dayton had released a slightly cheaper option or preferably, something obscenely brutal that'd clearly sit at the top of their LF driver range. I want something like a 1500-2000 WRMS 12" driver with a 3" dual 2 or 4 ohm coil, 30mm XMax, 25Hz Fs, 1.5 cu.ft Vas, 10' 3 or 4 layer spider in a cast aluminium basket for $300-400. And it should be user serviceable, with replacement cone/surround/coil assemblies available. But I want this with the anonymity that Dayton drivers can provide. No branding or labelling anywhere please. And the DIY market would go nuts for it. Both at home and in the car. Possibly even the pro market..

I have a brand new Klipsch spl plate amp and 1 utimax um12-22 I was going to build a hammer out of. Would this hit better with that amp in a full enclosure like you made?

Will this work in a Marty Cube?

With vented applications you never know what could end up contaminating the gap. I'm thinking for a large number of DIY'ers, gap contamination is most likely to occur during construction and final assembly. Also, with a daily driver car audio system, dirt/dust contamination is a legit concern. I've seen steel mesh there in other drivers, including Dayton's. However, in this particular instance, aesthetic appeal ... elevating the driver's apparent quality is also at play.

Given the quiet operation of the motor , would you recommend this for open baffle or is the Qts value too low ?

6:46 Am I correct in assuming that the impedance rise in that area will protect the drivers from seeing 800w and going over xmax? About 56v going into 4 ohm is 800w, but they both rise to a safe impedance where they will see less power and in theory never go over xmax at that voltage.

What size enclosure would you recommend for the x-max 15 tune 32 Hertz for a car

The small vents up top with the grates over them are for cooling obviously and the the mesh specifically is to prevent material from getting in and fought up in the coil gap. You are correct that acoustically there is no benefit to them. Although it would sound pretty bad if something got into the coil gap.

I'm thinking of using the 12" Max X to replace the UM in small sealed box in my ruck. The Max X makes more sense "in theory", but because the UM makes so much excessive bass, I'm saving power since I need to trim the EQ so much (-12db @50hz). I reckon I'd use more power running the Max X with the EQ set flatter, but it would likely sound better.

Great video

great infomation......im thinking of buying these mx 15-22 subs my room is 18x12x7 what do you think of 4 of these subs in my room in a ported box..?..im a bass junky lol have you built your sub box yet ..?...video ?

How will the Max-X do in a sealed box with more power and EQ (miniDSP) to boost up the bottom end? Would this be a decent sub for that? What size sealed box would be optimal?

Wonder if the apparently brand new GRS 18PT-8 Would make a great subwoofer on a tight budget.
