Hello, no I have no experiance with that driver. The information at the JBL site (graphs) indicates a much higher resonance at around 700 cycles were the 2001 is down around 300 cycles. I believe the JBL will only go to around 800 cycles and start to roll off. The 2001 will go to 600 in the 500 cycle horns. On the top end with lots of padding they'll probably go to 16-17k. 20k is possible but it looks like the response drops too fast to expect good results way up there. Overall they will probably sound great in the horns, but compared to the TAD they will be limited in both ends of the spectrum. There is a fellow, Paul Butterfield, selling a reconditioned pair of the 2001's for around $600.00. He can be contacted at paulbutterfield@mindspring.com Hope this helped.
