- I'd locate & use 813c duplexes since they're based on JBLs', E145 woofer. IMO, its' cone & coil topology will better drive the back-loaded horn of the C-40 ( 4530 ) .
- The 813a ( Altec based ) would be my second choice ( albiet, a close second ) followed by the 813b ( a distant third ) .

I have built hundreds of the single scoops ( 4530 / C40 ) and the altec / urei / jbl coaxes are too deep to fit unless you make a serious baffle extension.
