Greetings,I have a pair of JBL 2416 and a 12" pair Dayton DC300-8 12" Classic Woofer: http://www.partsexpress.com/pe/showdetl.cfm?Partnumber=295-320 ; I plan to put them in Altec Seville cabinets (4 cubic). What crossovers should I use for these. Can I please have some plan that would work with my drivers. Thanks.
