Default TS parameters and specs for these drivers???

I bought some loaded pa boxes today and managed to get the guy to try them out for me. I bought the lot for 150

Tops are : 2x 12 inch x 6 inch flare + RCL 393 phenolic comp drivers rated 50w rms each in 18mm plywood box.

Mids are: 2x dual 12 inch McKenzie Forte dual cone speakers rated 100w rms each driver,16 ohm each driver in 15mm ply boxes.Sealed cabs

Bass are: 2x 15 inch Celestion K15B-300 rated 300w rms each driver, 4ohms each in 18mm plywood slot reflex cab with chipboard baffle.

Well I can't complain as I got the whole lot for 150, and he tested them out with 3 amps and an active x over and sounded pretty good. But would like to change the chipboard baffles on the bassbins for plywood baffles and change the 1/4 inch jack inputs for speakon.

Top drivers are RCL 393 phenolic comp drivers, mids drivers are McKenzie Forte and bass are Celestion K15B-300. So does anyone know where more specs and ts parameters are for these drivers???

Would like to know the vc size,magnet weight,QTS,BL and Xmax for those drivers etc
