I hope Louis doesn't mind me answering your question, he's likely busy pushing orders out his back door.
I know the new drivers are 8" bicones, higher Q, lower Fs, and made of hemp.
I have read a couple of very good things about hemp cones for guitar amps, which are Hi quality wide rangers; Steve Howe was raving about them in an interview, and who here is going to question him on guitar ANYTHING? So I figured I should be interested too. Then Louis mentioned these babies were due.
Whatever they are made of, it's hemp plant fiber ("paper") with pleated fabric surround, which is a magic combination of ingredients for the organic portrayal of the essential midband from 200-500Hz, where the music lives, I don't care what anyone says. Look at Tannoy, Altec, Radian, Emilar, TAD, Selenium, JBL, Eminence, EAW, Ciare, BMS, Beyma, and on and on, paper and pleated fabric. Always has been.
I am waiting impatiently for the Good Word on these. No XO, Tannoy smooth, and intelligent whizzzering . A couple pix are on his site under News.
