These guys have a great rep, looks like they're backlogged at the moment: https://www.ebcelectronics.com/acurus-a100x3-Repair-Service.html

Spec wise they look very impressive, comparable to the RSW-15 but with slightly lower frequency response:

Klipsch offers an H-II to H-III conversion kit which includes all the parts for a reasonable price if you have serial numbers might want to call Klipsch parts and see if they can hook you up.

Honestly if you're H-II's are stock you might be better off just ordering TI diaphragms and updating your factory tweeters. If you want these I'll sell them to you let me know thanks.

Just a way to reduce output to an individual driver: https://www.simplyspeakers.com/speaker-crossover-l-pad-a-542.html#:~:text=L-Pad controls the volume of each individual driver,and minimum volume is as much as -40db.

I believe these are recommended for @ClaudeJ1 super Heresy project might run a little hot for stock H-II's without an L-pad.

These have been sold thanks.

I used these in Chorus II cabinets but the cabinets need to be modified slightly as the horn is much shallower than stock and the front board on the Chorus is an inch thick. I took a dremel tool and rounded the inside of the cabinet to get it to slip into place. As far as I know these should bolt right in to other models with this tweeter type no problem.

***SOLD*** Original A55-g drivers very low hours and work perfect just no need for them now thanks.

These are almost the same size as the k510 I've used these as mid horns in a few projects mated with k-55 style drivers with great results these horns are used and have light marks in the plastic as seen in the pictures no deep scratches these are very rare and fairly large asking $200 shipped thanks.

***SOLD*** These are the "cheap" version of Dave's MAHL tweeters same great drivers easy bolt in for a lot of the extended Heritage line

Need to clean house and move some extra stuff laying around these were pulled from my KP-301-II's and updated with titanium diaphragms they work perfect horns has some light rub marks as seen in the pictures I can email hi-res photos if interested $150 price includes fully insured shipping payment via Paypal friends and family thanks.

Hello, these speakers were made 1997-2001 I believe Klipsch has not offered replacement woofers for many years now best bet is to keep an eye on eBay as they do get parted out quite frequently or you can buy new aftermarket copies from a reputable seller although I have no personal experience going that route good luck! https://www.ebay.com/itm/154113477049?hash=item23e1e109b9:g:pxoAAOSwd4tT9lyK

I have yet to hear the new F-IV but from what I gather it is head and shoulders above the older iterations due to advancements in horn / phase plug technology, significantly higher end compression driver in the mid range and the latest and greatest extreme slope crossovers.
