Excellent work and right-up.  Fantastic (specialised) tool that you used to remove the shelves inside the cabs. I can clearly see why it only took 15 seconds.

Thanks

Additional info
I forgot to mention in the write up that the graphs all show an arbitrary x axis . The true sensitivity of this set is 84-85 dB working back from the mid bass at 89dB and giving up about 4dB for baffle step compensation. They do fine on SS amps 40 W and up

Correction
 I mention that the new back panel is fixed with low profile hex nuts this should have read low profile or low head cap screws but  then again I am sure  you got  what I meant............

Original two way , now 3 way,  with band pass ( hidden )  driver doing most of the bass duties up to say 100Hz , the front facing  mid bass taking over from there to 3K and then handing over to the tweeter. Another way to look at this would be,  to say, 2 way plus passive sub , but the band pass woofer is not really a sub
