This is some info I got from Mark tonight. I can't wait to get my hands on 4 of these.



Here are a couple of shots:

A short video of the excursion viewed using a strobe-a-scope. The noise

was everything on the bench rattling like crazy:

Here are some details you can share with the forum:


Voice coil is made by us, which uses a special Polyamide former instead of

aluminum. 40% lighter than aluminum, stronger and can withstand higher

temperatures. The coil will not generate eddy currents like aluminum

does, resulting in lower distortion. Voice coil will use aluminum wire

and glue that well exceeds the temperature of the magnet wire coating.


Cone is carbon fibre with pressed paper. very strong and sexy.


Motor made by us. Will have aluminum shorting ring to cut down back EMF


We are looking at ~33mm Xmax with Xlim at 44mm. This is the limit of the

basket design used.


In all, a serious step beyond the IXL. Listening tests thus far resulted

in comments of 'quick' and 'effortless'.

No, it was the 12 year old workers coming over to build them.

Was that really called for?

I planned on buying two more 21s after having my first pair built. I dont have alot of money like others and will have to wait and save. Mark said he can always make more of the same 21.


SO the initial order was a pre-order(300 deposit per 21) so Mark could see that enough people would actually be buying 21's. Mark said he can make more in the future also. Thats atleast my understanding. Lots of things change so who knows what the future will hold.

The carbon/paper hybrid paper cone and that tall surround look incredible. Coupled with the supposed performance of this 18, I can't wait to get a hold of one... Considering ordering my EP2000 now! Wish we had T&S's to play around with enclosure modeling

If it's priced right, it'll sell like crazy. Needs yo compete withe the inexpensive and efficient horn design offerings though. Or work well in a new, low knee horn design.

So will this be a decent replacement for a Maelstrom-X?

Oh my sweet Jesus!



Suuhhhweeeeeeeet!

4 of these and an FP14000 hmmm.

Yeah. That's what I'm thinking.

I'm looking for the rating, myself. This sure looks like an awesome driver. Any ballpark estimate on the price on one of these and availability?

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.

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.

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?

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.
