Hi Everyone,
I have asked this question once before without great response so I figured I would ask again...
I am now at the point where I am finishing up my stereo Hartsfield pair and am again thinking about bass woofers and crossovers.
Right now I have a pair of 130A woofers which I plan to swap with other 15" drivers for find what I like best. I fear the 130A cones my be to compliant for a horn loaded enclosure. (Also one suspension is much stiffer than the other so I doubt they are well matched)
My question is, what would be some other good woofers to try and swap in?
I do not have a wide range of experience with the JBL product line and could use advice from someone with experience. The 150-4c's are not an option, at least for now due to thier cost and I am willing to bet that most are tired and worn out since cones are unavailable. Also, it is difficult to find a suitable replacement without experience since there are no published or measured Thiele/Small parameters.
If anyone has woofers that may fit the bill and are willing to part with them, let me know.
As a side note, I have started to model the 130A speakers with my 3115 crossovers in Cadence using the approximate parameters found here:

The response is very peaky (+5dB at around 200Hz) with very nonlinear phase response.
I recently acquired the Dayton Audio DATS speaker test system which I will use to to characterize my final woofer choices and optimize crossovers.
Thanks for any help,
Matt
