JBL Concert Series and biamp monitors?

dan

I’m using a DBX 260 and I’m preparing to setup an old JBL system. It consist of dual 18" subs (JBL speakers, JBL face loaded clone cabinets) and JBL Concert Series 4852A tops (version with 12" and 2" horn - no tweets). These are in great shape and sound excellent, but are old so I'm not finding any tunings for them. The 12's in the tops are on the same plane as the 18's, but I was wondering if it was worth setting delay to correct the horn offset? If so, are there any recommendations or articles I can refer to?

Also, we just reworked our monitor wedges, installing RCF 15" coaxial speakers. Was wondering if tunings and/or delay settings/recommendations might be available for these?

Thanks, Dan

I think the closest published JBL tuning would be this:

It is for a SR4732A which has similar components. I wouldn't put much faith in anything other than the XO points...I think this tuning was set with a BSS FDS366 Omnidrive. What amps are you using? Different amps will change the values a lot. Post some info on the RCF monitor speakers.
