Thanks for sharing.

Actually this is an old (SD 18el) spec sheet. I think the power rating has been revised to 1000 watts RMS from the time I first heard the SD 18el almost 3 years ago.

As for the Xmax, I too find it underrated and so was my previous SD18. It's the predecessor of the SD 18el which only registers (Xmax of 5.0 mm only) . But the old SD18 is a hell of a speaker and I consider it as probably the best woofer I had. Nevertheless, I'll try to ask for the latest SD 18el spec sheet if it is available.

As for the other parameters, I think the PD should be a better speaker over-all since it's a Precision Device .

Just my two cents.

SD18 old series. For me the best 18" woofer I had.

^ yap you get what you paid for almost the same motor structure yet the other has more BL, This means the magnetic circuit where optimized, I could only imagine what the BH curve looks like, more linear, cause they where able to use a voicecoil with an 11 mm Xmax. If only someone could provide me with the the "other engineering data" cutaway view of the motor structure, the alloy or grade of the steel part (toplate, backplate) the grade of the magnet etc. or better yet the FEMM analysis of these beast. So that we will be able to see what is really going on "inside" the speaker and why the other manufacturer is charging that much. just my two cents

AB-36C...looking for 18" stroker mechanical dimension no luck...i lost my copy.
So there is no way i can tell if the JH's and the PD's will fit in.
if ever they do fit in...they will perform very differently from the original.
it may surpass the original in terms of robustness due to JH186 have approx. 6" VC and PD1850 have approx. 5" VC...if memory serves me right CV stroker have a 3" VC which requires an adequate cooling system...correct me if i am wrong.

One thing i am sure of if ever they fit in...with the JH's and PD's you got more sensitivity, SPL and power compression is so so far away.(Block of 4 boxes)

i used to have CV's a long time ago...Junior earthquake L36JE and the Senior earthquake L48SE...i know how they perform. i still have those original plan.

If ever your going to try and pursue to do the driver mods...good luck.

have fun,
jojo
