SPL Curves for JBL 123A-1 drivers

[maLx]

Looking into building a set of monitors with some vintage speakers. Chose the JBL 123A-1 drivers for low end. Going to pair them with Hiel ESS AMT's. Question, does anyone have SPL Curves for JBL 123A-1 drivers? I did find the QTS and dB ratings but looking to see if they are flat or if I need to build in some resolnation into the box (excuse me if I'm talking like a noob). Want to avoid using a DSP with these, trying to go all analog. Shooting for 100-1000hz range or somewhere on these with these 12" drivers.

Thanks!
Joey

See Here about half way down the page is a FR comparison of the 123A in an L100 and on a curved baffle.
