The next big driver hype: Textreme


Just thought I'd mention it now, since in a few months we are probably going to be seeing a number of drivers, possibly tweeters as well as mids and woofers of this material.

At least one manufacturer, SB Acoustics (think Tekton tweeters, among others) is releasing a line of woofers for DIY and OEM this year.

Fun stuff.


Best,

My new Purifi 6.5 is incredible..
Looking now at HiFi Compass.com  for the excellent testing methods of many woofers and tweeters of all brands and materials . An excellent source of up to date information.  Like to see the latest from SB..Tom
 




     What is that....A dream?

      Yes, that's Textreme!

     Sorry, I've been working on their upcoming marketing campaign/blitz non-stop for weeks now and I'm going a bit bonkers.

Thanks guys! That article was really fascinating speedbump6. It will really be interesting to hear speakers with this technology in the future. 
I saw the Purifi measurements.  I was more than a little puzzled, as the claim is that the IM distortion is coming from doppler effects, but the Purifi still moves the same way.

Weird.
It is all about a polarity of shear that travels the cone and returns on both sides of the cone and thru the cone back towards the point of the intial wave launch. The voice coil. How many wave collisions will there be on a flat moving foil.. how many more will there be on a moving cone suspended between at least 2 very different materials and shapes each with their own geometry and shear velocity..many more collisons of waves and eruptions and direction changes.

Pay $, Point  German laser scanner at driven cone, review graphic results over entire surface of cone: blue in phase to input signal, red = out of phase, review results and weep... or rejoice

repeat until perfection attained at reasonable cost.

The shear also travels the basket the flange the baffle and all sides all at different material velocities traveling in near infinite and changing directions. All tied back again to the next wave launch from the voice coil. Tom

Eyeballing the waterfall plots of similar drivers which use different diaphragm materials, Textreme diaphragms are competitive with Beryllium as far as cumulative spectral decay goes. Textreme’s settling time is extremely fast.

Based on encouraging initial tests a couple of months ago I contacted a company which manufacturers drivers with Textreme diaphragms about having something custom done. Apparently the company thought it was a good idea, as it now looks like my "custom" version will become a regular catalog item from this company, probably around the end of the year or the first of next year.

buying into the hype bigtime
Between the Purifi and Textreme drivers it is a really fun time to be around if you are in to 6" mid woofers.
Implementing a more refined mechanical grounding method that couples the Purifi driver to my cast speaker cabinet. I am able to externally tune the system harmonics much the same as I do with my Grand Concerto endpin system for cello. If Geoff were around and I really hope he is we could discuss the importance of reducing shear wave interference in most everything including all speakers. Tom
