ELIPSON | LA PERFECTION DU SON
You may recall my visit to Jullien Thaler and my story about his collection of Elipson speakers and paraphernalia, most probably the largest in existence. You might want to read it again here ...
Jullien, whose nickname in his endeavours elipsonesques is Violet, had a website where a lot of this information was stored in a somehow erratic way, as he started that website way before any serious web builders were available... It was at risk of disappearing altogether...
So he decided to start from scratch and six years and 667 pages later, he has now published the Elipson Bible with an enormous amount of new material, historical photos, reviews, schematics, patents, etc...
I thought i knew a lot about Elipson, but in fact it’s about the same as my knowledge of Saint-Julien, that famous plot of land in the Bordeaux Right Bank, where I know only 14 Chateaux out of 48, and it’s even worse if you go about the whole Bordeaux region which has around 4800 wineries and I might know and drank less than 200 in half a century! So the comparison is very appropriate!
I have chosen to show you this particular page, as this patent is what makes Elipson speakers sing...
For sure, the use of resonators, although seldom in speaker design, was not entirely new, but what Joseph Leon found out is that in order to tune the resonator properly, one need to adjust the Q factor of ditto resonator, in other words its bandwidth, hence the second opening...
Monsieur Leon went on to patent time alignment which is important in getting the group delay just right, so the timbres of instruments and the slew rate of the music are reproduced correctly.
The late Siegfried Linkwitz and fellow HP colleague Riley did some more research on how to achieve this in the crossover as well.
So i won’t lose any longer on the subject matter and will entice you to read the Bible yourself!
