How 101 can you get...................



These were one of the things the Japanese market wanted. The 902-8A with 811B would be much better replaced with a large format driver (say, a 288 w/511E),IMHO, if it would fit. The cabinet is probably not deep enough without cutting the backboard for the driver (sans early 846's w/ 804/806 & 811). A 500 or 800hz crossover seems fitting for the 411 in the 9861, as in the 873A Barcelona. Maybe the horn load yielded some civilization for 1200hz.
1200hz & 8000hz works for my horn loaded 515-8LF's w/ 288-8G/511E, & 802-8G (A7-500WII).
