I have know Michel Visan for some time, in fact since his time as Technical Director of Siare, then the main competitor to Audax, these two companies having the lion share of the French drivers markets.
When Michel started Davis, he was one of the first (with arch rival Mahul...) to try Kevlar and carbon fiber cones.
I have never been convinced to use kevlar for midrange drivers, as I find them pretty dead. I could use carbon fiber for woofers, but never did, mainly for cost reasons, as paper woofers would mostly do the job and be almost half price at the time.
I also think - and this is a very personal view - that most driver manufacturers are not necessarily the best at making good speakers, and Davis fell into that category, again in my view, for a long time.
But walking into their suite at the show, changed that opinion within seconds.
Obviously the Karla is no ordinary speaker; it is a 3-way, 4-driver contraption with a 93db sensitivity, 25Hz to 35KHz frequency range, in a twin enclosure.
MV is using Kevlar drivers for midrange and tweeter, and carbon fiber for the bass.
Interestingly enough, the cut-off frequencies of the filter are 90Hz and 4KHz, my favourites ones, as it gives a chance to the main part of the spectrum to be reproduced without any phase distortion.
I guess this is one of the reason why this speaker plays music, rather than being a high-end hifi speaker. I stayed quite a long time, listening to a very good demo.
It was quite touching to see Michel and his wife sitting at the back of the room, gently (dare I say, lovingly...) watching their two sons running the show...
Quite a refreshing sight...and sound!
The Karla costs 15,000 euros, again in the range of the Elipson 4260, and the Waterfall Niagara.
