definitely kick some ass. The "problem" with the passive is the points get quite a bit higher, with the gentler slopes. You can cross from the 15 to the 8 at 341 with a 24db LR active filter, but since the passive is 12db, they cross at 600. Also, JBL recommends .416ms delay on the woofer; not something we're going to accomplish with the passive. HOWEVER, it will be nice to be able to lug them around and run them off one amp or powered mixer, and also drag them downstairs for HT use. How many of them did you buy?? MBB
