$400 dollar price range

By my calculations, this matches the Maelstrom-X dollar for dollar by displacement.
It actually has a fraction more displacement and if at $400, then it's $20 less than the original price of the Maelstrom-X.

So basically, the same sub & value, displacement-wise. Maybe a tad better.

Beautiful.

Yup. Been modelling around with it in Unibox since my last post.

This is one serious driver. Let's just hope the supply of these is as serious as the copious amounts of bass one of these will produce. Dayum.

The WinISD default recommended -3db enclosure comes up as a 17hz tune in only 9 cu^3.
I modeled it with a high pass at 17hz.
It starts to exceed x-max at 4500 watts.

Very close, although it appeared to model kind of closer to an LMS in a sealed box.. q = .5 in only 200L whereas a mal-X needed 450L to get q = .5

but the maelstrom had a bit more bottom end efficiency, a bit less top end efficiecny.

It almost seems as if this driver has been optimized to work with an EP2500 as it squeezes every watt out to get to xmax

Would be interesting to see distortion numbers comparison between the two drivers. I think the Maelstrom-X had XBL2 technology didn't it?

Wish I could find a Maelstrom-X WinISD file to use.
Time for me to get some sleep or I'd just create one.
But it was always difficult to get true specs for the Tempest-X to properly model it. Dunno about the Maelstrom-X?

Sorry, I wasn't referring to anything other than displacement.
I haven't been able to model it against any other drivers yet.

I've never seen it referred to as Lp, but it seems to be the only parameter that makes sense to represent sensitivity. Isn't 92.9 high for a driver with such high xmax and a real bottom dweller? I'm not complaining (amp friendly actually ) just rare to see.

I've got the specs for the Mal-X in Unibox and that's all the specs you'll need.

In my model it actually looked slightly less sensitive than a Mal-X Gen II so I'm not sure we're they're pulling the spec from.

I mean it works in half the space so it's all good, but the mal-x with about 1600w in 215 L has about the same transfer function and SPL as the Mach V fed 2300w in about 130L - below 60hz at least.

Above 60hz I don't know what kind of rolloff the Mach V has. If they really optimized its inductance, its sensitivity spec could be inflated from the high sensitivity at higher frequencies above the crossover point (great for a bass bin). The Mal-X started to roll off 6db/octave starting around 90hz with a -3db point at 200hz - which could describe the difference in sensitivities if the Mach V is -3db closer to 600hz or something wicked like that..

I don't think any of us would complain about optimized inductance

Very nice specs.
I've already asked locally if they'll be importing some.

Mark has advised that you run no more than 1200 watts through this driver at the moment. I have played around too and it is very difficult to model in a low tune with say 2000 watts which it can take without going over max excursion but port velocity is very high. Malx models slightly better. I got quoted from Mark yesterday approx $450 per driver so I am going to wait for the blueprints before I make any final decisions.

It does model very well sealed though.

1200 is to be safe and cautious I am sure, very conservative. i dump more than that into IB3s and 1803s.

A quality passive radiator will do the trick...

...and i'm assuming Mach V plans to have one available... around 2300g mms / 36mm xsus optimized for this driver?

What size is optimal for ULF if fed a nice chunk of power with eq?

The bigger the better. Model up 20 cubic feet vs 40 cubic feet vs 80 cubic feet vs 800 cubic feet vs 2000 cubic feet... changes wont be drastic. If by "ULF" you mean 15Hz down to 3Hz.

1.5-3cuft per driver depending on input power.

I think 4.5 to 5 cu.ft sealed, give or take works well with this sub.

The amount of EQ necessarily will depend on placement and room gain. Concrete walls + corner loading (for an ULF assuming you've got other subs to smooth out the response) and you could have pretty sweet results with minimal EQ.

if you can go 9 or 10 cu ft you might be able to make a really nice passive radiators sub.

Thanks for the responses.

How much power is the biggest question, then how much EQ... could sumone who has been modeling these do a few separate plots, say 1 cubic foot with 500 watts, 1500 watts, and 2000 watts, then another in 2 cubes same power levels to compare, and another in 4 cubic feet? Im going to guess that this thing will take 3kW like the other drivers like it did, so an EP4000's 1800-2000 watts would be the norm? How about 1 more plot at 8 cubic feet 500 watts-2000 watts?

damn it man I said F it and started entering it to WinISD, had to google HTS's entering driver data proceedure, almost done... then I see what a swell guy you were providing a download FRACK!



I never used to change which alignment it autocalced, sweet! Of course I did the -6dB lol 12 cubes 13Hz

Then I had some fun with a 20cuft enclosure 48" long 8" port 11Hz tune only 400 watts gives 110dB to 11Hz 115dB from 15Hz on up. EQ +8dB @ 15Hz and +3dB @ 30Hz, used 10Hz HP to compensate for electronics rolloff. Xmax is surpassed from 14Hz-18Hz but still under Xmech assuming this is 40mm-44mm... peaks at 38mm at 16Hz... bumping down the EQ at 15Hz a notch or two would fix that if it worries you. Air speed peaks at 22m/s @ 12Hz and would be even less with less EQ.







Sub at the bottom, port going strait down from the top, 6' enclosure standing in a corner with 8' ceiling the port would load into the corner. Otherwise do a slot port.

That enclosure is going to have one hell of a low port resonance with a 48" long port.

So these are the specs



Fs 19, 92.9dB, Xmax 34mm........um, that seems almost impossible to have that high sensitivity . If its true then I might be selling some LMS5400s

Pretty damn sweet for $400

Anyone know the Le value??

Still trying to find that out. I'd sure like to know. For right now, I'm using 4mH as a nominal number for that.

I think the FiCaraudio 18" IB drivers still move more air then this one.

Maybe just by a hair. These work in small sealed boxes though.

That sensitivity is for 2.83V instead of 2.0V so it's more like 89.9dB.

Seems to be a cheaper and slightly less powerful drop in for the LMS in the Gjallerhorn enclosure...Cool. Anybody need outdoor HT type output levels?





Half-space 100v input (3100w peak)



100v excursion (Needs 14hz hpf)
