My old JBL L110 Monitors had paper mid and bass drivers - wooo, they were fun! Musical excitement by the spadeful.
Their drivers were undoped pure Kevlar cones. Kevlar has a midband resonance that can either be filtered in the crossover as B&W did or sort it out by doping the cone. Filters kill music.jandl100 wrote:Ah, you mean the dopes at B&W didn't dope the Kevlar drive units properly? - they sounded kind of soggy to me.

I only ask because many systems today, using any source, seem clearer and easier to 'hear through' than they were back in the mid 70's ime. Not saying it'll make a silk purse out of a bucket of turnips, but it does seem to help them no end to use an amp with good damping factor (if you believe in such things - Harbeth don't:(), decent gauge speaker cables and a good digital or clean vinyl source (not the way we used to site a turntable, with no real thought for isolation).
Yes, I quite agree with you that modern electronics and ancillaries can raise the game of older speaker designs. (I think I've made the same point myself on AOS).
The reason I use a duck in all my avatars goes back to a disagreement I had with a guy on the Wigwam who insisted that my latest fave speaker purchase at the time (Bowers Active One's, remember them?) had unacceptable levels of 'bextrene quack' from the cone material used. Try as I might - and compared to a nice example of Quad 57 stats - I couldn't hear it with the modern electronics I was using - I said the only quack I could hear came from a nearby lake with ducks onand changed my avatar accordingly. I invited the guy over to have a listen (to the speakers, not the ducks) as he wasn't too far away, but sadly he didn't accept the invite. It would have been interesting.
And yes, I've heard the vintage Rogers Export Monitors previously mentioned with modern electronics, as well as more modern Spendor SP1/2 and others. After the initial "Wow" factor of tonal neutrality, which lasted a quite impressive couple of days with the SP1/2, all of them are like watching paint dry as far as I am concerned.
