Klipsch may have them. Since I own a lot of Palladium speakers, I inquired about driver part numbers and availability last year. This was the response from Klipsch support:

Thank you for contacting Klipsch! Our sincerest apologies for the extremely delayed response, we've been experiencing substantial traffic increases.
You are correct that all Palladium models utilize the same K-151-OB tweeter (part #129112).
The 4.5" midrange driver is also the same on all models (part #1007682).
The 7" woofers do vary a bit. Part numbers below.
1010100 P-17B 7 INCH WOOFER
1007631 P-37F 7 INCH WOOFER
1010099 P27C/P27S 7IN WOOFER
The 8" woofer on the P-38F:
1007632 P-38F 8 INCH WOOFER
The 9" woofer on the P-39F
1007633 Woofer 9" P-39F
I took a look at our inventory and it appears we do have all of the above drivers available as replacements if needed, though there is only one of the P-37F 7" woofer available.
Please let me know if you have any questions.
