Save yourself $12-25k, these JSE Model II’s sound fantastic.
Richard Modafferi’s 2 patents: Infinite Slope Crossover and Bass Shift (unique way of using the 10" and 12" woofers).
Used, nobody knows about them, they cost very little. They were a huge hit when introduced, BUT, they decided to make the enclosures themselves. Late, Late, Late, cancelled orders, Harveys stopped carrying them despite how awesome they sound.
Joseph Audio still uses some of Richard Modafferi’s patents. Jeff was a salesman at Harveys when the JSE’s came out.
Good luck finding something sounding better!
My friend has mine, I went back to my Vintage Horns I inherited from my Uncle. Replacing the Dynaudio D21 Tweeters was the best thing I ever did, the D21's were famous for burnt coils. The SEAS tweeter is John Solecito's recommended replacement.
Have seller confirm if the 12" woofer is the original dual coil one.
