Anyone know about sforzando design JL One

Can't find much info on this speaker system but I hear good things about them. Any input would be welcome
I was told of your thread at our NJAS meeting today. I own a JL-1 speaker system that has been a bit of a test bed for the designer (he's a member of the NJ Audio Society) so it's been tweaked a bit, and another member of NJAS also has a stock version of the speakers; there may not be others out there other than for the designer and the man who builds them. I love them, but they are definitely not for everyone--those who listen exclusively to pop may be disappointed. You can e-mail me and I can fill you in on them in more detail; if you live near the NYC area or are visiting you're also welcome to hear them. If you like symphonic music or well recorded small-scale classical or jazz, and particularly recordings made in very large reverberant spaces (especially choral or organ music), these speakers are excellent. They create a huge three-dimensional soundspace, go down to about 20 Hz or lower, and can sound surprisingly real with the right recordings and associated equipment.
I too have a set of these loudspeakers. They are everything rcprince said and more. I can confidently say they will be my last speaker system. I know this might be a vague term in audio, but they sound like music to me. I am also in the NJAS and they normally retail for around $12,000. I can truthfully say that they compare with speaker systems upward of $30,000 that I have heard. I am running the bass units with a solid state amp and the satellites with the Quicksilver V4's. To say that I am happy with them is an understatement. Even though they are about a 5-6 year old design, they still compare favorably with anything built today. I live in South Jersey and if you would like to hear these wonderful speakers, drop me a line. They are a bargain at their price.
