I merely couldn't resist here; now that the Maelstrom-X is shipping, we need another Fox to chase. Not to mention it will help distract my thoughts as I put the basement back together.

Ask yourself mortal , do you have as much displacement as me ? The answer is no unless you have a Windmere fan sub.

If the Sick-o 21's ever materialize and you buy some, throw a party with an open invite. KC is only an hour from me.

I've not given an update lately because there isn't much to give. We have quotes on the first round of tooling/parts and we are going back to re-design some of them to make them cheaper to build. The first quote for machine work came in way high so we are working on ways to decrease the part cost via design.

This is just part of the process, nothing to get excited about.

Kevin, how about telling us what are your target parameters for 21" sicko? Also any decision regarding cone shape and material(s)?

Absolutely not! It will work in boxes about 30% larger than the Maelstrom. There have been no choices on the soft parts at this time.

Kevin,

Take your time...give no info to the wolves. When its ready I will be there for two.

I like the Maelstrom-X's so much I may order two more...and do the one in each corner experiment.

What!

One thing is for sure,I am keeping my Acoupower 18's and will add the 15's.

Driver of this quality and performance level are keepers.

You guys must have your own version of reality.

Here's mine....



To answer your question Larry, It will probably be sealed. PR's have my attention, but I have concerns about using a pair of 18's. 21's would ease a few of my concerns. 4 PRs per driver is too costly. 10" monster ports have other side effects as well. Sealed & Simple is looking like a winner unless I'm convinced otherwise.

nice find V,
cool specs. The low mms makes me nervous about the cone not being structurally sturdy enough, hopefully it's something special. The X-Max VS X-Mech is real lean for a driver rated at 4KW program 10KW peak

such a tease to not have a picture of it

Dan

Wow that looks like almost like a 21" version of the Aurasound 1808 with the neo motor, light cone, and high sensitivity but with substantially more Xmax.

BTW, talked to the designer of these PASUB drivers. The listed Xmax and Xmech values are peak to peak, not one way. Still, 20.2mm Xmax is extremely good for a driver having +95 dB sensitivity.

I knew that too, but I wanted to see if anyone became excited before revealing...

Still a formidable amount of excursion. Looks mostly like a sound reinforcement driver, but its interesting. It was supposed to be demo'ed at NAMM Summer 08 last week. Didn't hear anything about it since.

21" will be as common as 18" in a few years, Just like electric cars.

Nice find. I wonder what it's going to cost? A 21 with 20mm xmax should do plenty of damage. Even the B&C 21 with "only" 15mm will probably get stupid loud above 20hz.

I got word some time back.

I cannot guess who is designing them...

Ask yourself mortal , do you have as much displacement as me ? The answer is no unless you have a Windmere fan sub.

Only 15mm on a monster of a 21"...and the B&C only hits mechanical around 30mm !!! That is massive ,two B&C 21's should be a delight.

I was many time on the verge to click BUY two times, I will wait to have my massive wall of subs ready to order two 21's.

Well, if one tuned the driver to PA standards and used a subsonic filter, the power handling isn't all that big of a deal. It is easy to forget, just because a driver has X power handling doesn't mean it was designed to handle all that (in any alignment) at one frequency. A normal input signal will be delivering output from all across the frequency band, not just one spot, this makes it a lot easier on the excursion of the driver, but harder on the amp/voice coil. Whenever I can, I try to design a system (amp/driver/box/filters) to be able to push the driver past xmax, simply because in real world instances, the xmax of the speaker will not be pushed, but rather, the amp will be, as long as the voice coil can handle the extra power.

OK Army,
it was just observation, and regadless of power the X-Max/X-Mech is lean IMO. I just bought 2 Maelstroms that I have the same opinion of and I'm not bashing it or Dan Wiggins. Just making an observation, no need for getting all worked up.

Anyone know what the cone is made of? It would be kick a$$ if it could stand up to horn loading.

Dan
