Wow! the latest motor from Adire Audio

I thought you guys would like to see this:  http://www.adireaudio.com/Files/Dan/Parthenon/

Man I love that company.

that makes the cone go up and down in lame mans terms.

It is a beast of a motor tho. to bad it starts out at 3k$

Just some great quotes about it to get you an idea of what this baby can do:

"Flat anechoic response to 6 Hz. And capable of over 66 liters of linear air displacement! That will generate reference level (121 dB SPL) output at 20 Hz, when sitting naked in a room - no room gain, no baffle, no box required."

"Pretty easy to stretch the motor to 12" of peak-to-peak stroke"  And BTW, that is linear stroke, not just an uncontroled cone moving around.

Yes it is expensive, "But considering what you have here - more output than 12 Tumults in the base 2004 CES trim! - it's a relative bargain."  BTW, their Tumult driver is a mean 15" monster and it has the largest linear displacement of any sub on the market right now.  Their new sub can outdisplace 12 of those subs.  Here's a link so you can get a full idea of the Tumult: http://www.adireaudio.com/diy_audio/drivers/adire/tumult.htm

And just in case you are thinking that it is just another company making claims that they can't back up, this company has a history of reaching these goals.  They always match what they claim.  Their Brahma driver was reviewed in Mobile Entertainment a few months ago and actually exceeded some ratings.
