What would be involved in updating Hersey II’s to Hersey IV’s?

UPDATE...I found a pic and some info on a Klipsch community forum along with this quote from a Klipsch dude at RMAF: "In speaking with the Klipsch rep, he stated the change in the Heresy IV from the III is:  (a) the speaker is now a bass reflex speaker with port in the back, (b) all three drivers are updated based on what they learned from the Forte III, (c) the box is about 1" taller to accommodate the updated design, (d)  the riser is updated (in black and no curve), (e) grills will be updated , (f) binding posts are updated to a higher quality, and (g) in addition to the standard three finishes, the IV will be available in distressed oak with the linen grills." Supposedly to be announced 12/19.

Wolf, glad you found it. All that was needed was to Google : Klipsch Heresy 4......Roy Delgado is truly taking these PWK designs, to the next level, imo.....

Thanks for the info wolf_garcia,

I  was on the forums last night and all I found was the Model III, Heritage series, special edition.  New tweets, midrange, woofs and posts.  I must have been in the wrong area.

I’ll look again tonight.

Thanks again.

There's a bit of hyperbole in both of the previous quoted statements.  Klipsch speakers are abundant and there are a number of sources for upgrade parts.  My KLF-30 speakers were a lot easier to listen to after I replaced the original tweeters with aftermarket parts.  I'm not sure if the crossover upgrades made a lot of difference, but they were 30 years old and it seemed like a good idea and was pretty reasonable.  A bead of Titebond III around the back panel kept them from rattling at high volumes.  An inexpensive and worthwhile upgrade/repair.

My Heresy I speakers sounded really good when I bought them.  I replaced the woofers mainly because I had some spares that I had used in the KLF-30s.  The Bob Crites tweeter upgrade seemed to give them a little more detail, and applying Dynamat to the outside of the mid and tweeter horns seemed to make them more cohesive in the mids and highs.  I replaced the crossovers because the ones from 1976 were definitely showing their age.

Were any of these upgrades game-changers or take them to a level way above their price point?  I don't think so.  Was it a waste of money?  I think I put maybe $500 into both pairs of speakers and they definitely sounded better after the work I did to them.  To me, it was easily worth it.  A lot cheaper than some fancy cables or power conditioners or many other things people do in their quest for improved sound quality and probably more impactful than most other upgrades would be for that amount of money.

You either like and appreciate the Klipsch sound (especially at their price points), or you don't.  If you don't, then the "lipstick on pig" analogy makes sense.  Why try to fix something you don't care for in the first place?  If you do and want to get the most out of them, upgrades are worthwhile and inexpensive.  Perhaps others have experienced more dramatic improvements than I have with their upgrades, but my advice would be to have realistic expectations in regards to the results.  The Klipsch forums have a wealth of information about upgrades.
