Let's see if I can summarize what you have:
- 2 EAW full range boxes of some kind that you normally run bi-amped
- 2 Yamaha S3115H boxes with replacement JBL woofers
- 2 TL505 subs
- 2 TL505 subs with replacement Carvin drivers
- 2 CE 1000 amps, normally used one per channel for the bi-amped EAWs
- 2 CE 2000 amps, normally used one per side in bridge mode for the subs
- Some undefined crossover or processor
- I assume some undefined mixer
Is that an accurate summary?
Do you have to run the EAWs bi-amped or could you run both off bi-amped but off one amp? What is your mixer and system processing and what EQ and other processing might they provide?
You did not mention anything about the pattern of the boxes involved. If your concern is coverage then that is probably going to be a crticial consideration. If nothing else, it makes it difficult to offer recommendations without knowing the speaker patterns involved. Also consider that your subs may be greatly omnidirectional.
Are you thinking of running mono or trying to be stereo everywhere or perhaps some mix of stereo for some coverage areas and mono for others?
Dick hit it on the head with what may be realistic and if you don't have what is necessary to make it work acceptably in general then you may want to focus on making it the best you can for a more limited area.
