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.
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
