Here are my opinions based upon me doing a Super Heresy upgrade (and we both know what most opinions are worth!):
1. Yes, you will get a bass boost swapping in the Eminence Pro 12A, and the port seems to help in that as well. I left one of my boxes unported for an A/B test and you could tell a difference, especially if the ported speaker was near a wall or corner. The woofer upgrade does work well for me, in my particular room.
2. Bass boost won't have anything to do with the crossover changes. No extra power is heading for the Pro 12A either before or after performing the x-over alterations. The crossover changes are to "harmonize" the upper portion of the woofer frequencies into the lower end of the squawker, and then the same to the tweeter. I feel that Claude's crossover changes are well thought out and executed. To explain this concept a bit further, the amplified signal is fed into the speaker and the positive connection goes into an inductor, and then straight into the woofer. The purpose of the inductor is to roll off the higher frequencies (plus the side effect of eliminating any possible DC current getting through).
3. You can use anything for the port material, as long as it is the same internal diameter, length, and most likely structural rigidity. Others might say something else.
4. I really can't answer the question about capacitors, because I am not one of the guys with extra critical sound discernment. Some claim to hear the difference between lower and higher priced caps, some don't. Some people also claim to hear differences in speaker cables. I don't remember ever seeing empirical evidence to this, where a double blind test was conducted, maybe someone else has. I went for the inexpensive caps, and they work fine for me.
5. Replacing failing caps will most definitely change the sound, usually moving the ball back toward the original line of scrimmage ( Closer to how the speakers sounded when new...).
As far as tweeters go, I didn't do anything more than the adjustments on the autoformer to them. In a recent hearing test, I couldn't hear much above 10 - 11khz, so upgrading those would have done nothing for me personally, due to tinnitus.
I have simplified some of this, and the more knowledgeable members may weigh in and elucidate further. @karlti

Those horn drivers appear to be the size of a Frisbee. Make that a brake drum from my old Plymouth.

Hi I am looking at a pair of 1985 Klipsch KBBRL H/2, rosewood is perfect but I really can't find any info on these. Does anyone know approximate value? Any help would be great
With that veneer and finish, I would expect the value to be rather on the high end for 1980's Khorns.

No? And why not?

Does anybody have an info on how hard it is to change out the tweeters on these? And what those tweeters might cost?
Shouldn't be that hard at all to replace. These are basically Heresy II's on steroids, and that's a damned good price on them. These are solid Birch Ply if I am remembering correctly, and much more robust physically and electronically than your normal Heresy models.
Offer the guy $250, seeing as the tweeter pair should run you $100 if you put K-77's in them. I have a pair that I could be induced to sell.

Just came across this: https://skyfiaudio.com/collections/speakers/products/klipsch-cornwall-vintage-speakers-in-oiled-walnut-1977-survivor-pair
Its at a shop, so I figured it would be more than out in the wild, but that seems like a ludicrous price for these? Maybe I'm missing something?
By this logic, my all original 1977 Heresy pair should be worth $2,500. Anyone want a really spectacular set of HWO for that price?

That person has no idea what they have
Then why did they take them down and add a grand to the price?

The listing was taken down because of an "error" in the ad. He put them back up for $2,700.

seeking information on Heresy II “ 1985 ?signature edition “ , serial number 8644405. I don’t understand signature edition.
The "signature edition" were a special edition of Heresy, with a different front emblem. If I remember correctly, Paul W. Klipsch worked on those himself.

Passing away at any age is sad, but at such a young age it seems all the more tragic.
All too young, I agree. I'm not too far off from his age myself, and I will miss bantering with him. I hope he and PWK can chat, somewhere in the universe beyond...
My condolences to the Payne family, and our thoughts and well wishes go out to you. He will be missed.

They are actually HWO, Heresy Walnut Oiled. Walnut stained and oil finished. I agree with the pricing model as stated above.

Good call, there. Jim will fix you up with decent prices.

I would hope so. These cost a tenth of your Khorns, brand new.

The banana plugs will fit properly. If you look closely at the tips, you will notice that they are hollow, with the sides being leaf springs. This allows them to fit snugly in holes of any close size.
Just make sure that you screw the binding posts all the way in before inserting the plugs. You don't want to bend or break anything.

Always nice when something like that happens to a friend you know. Great for a laff or two six months later after everyone's done w/the praise. That's when you get the back story on it all shared openly. Always nice to have good friends who have accomplished something other's can't do. Great award but I'm still waiting on mine. hahaha
I hope you get to walk that aisle one day.

...Jim West, best known for his guitar work with Weird Al. Talk about a guy that can play anything, in any style. His personal passion is for Hawaiian Slack Key, and he just won the Grammy for best album in the "New Age" category.
The odd thing about Slack Key is the weird tunings, because guitars were left behind on the islands after the early explorers visited, and no one really new how to play them. So the indigenous people tuned their instruments differently than anyone else, which means completely different chords. Different hand shapes. I could never master a guitar with the "normal" tuning and the myriad chord shapes. Then add on a dozen major tunings from all the different islands and styles. Mind boggling.

Ok thanks. Still to me the build looks a lot better than many of the home spun diy jobs I see posted on this site from time to time.
Baffle screws can be changed and counter sunk to improve visuals after the fact, that's not very much of an issue if it really bugs someone. The wood screws look to be well placed and not at all random and he used lots so this will be a solid cabinet. Given they come with parts that sell for more than stock ones would I don't think the asking price is much out of line (if lots of CW sell in this area then the asking price is going to be seen as high). I understand lots of folks don't want clones but if that is not an issue and they are well built as they seem to be lower offers could always be made citing the non original build to possibly leverage a better sale price. Remember also that lots of guys buy beaters and then refurbish them (these look pretty good as is). The market place will determine the value of these as it usually does. Should any members be close enough for an audition please let us know what you think about the fit finish and sound of these Cornwall clones.
I was mainly making a joke. Other people got it. But not everyone is the same, I guess.

I have no interest in these loudspeakers. I have looked at the photos and the cabinets look better than lots I see for sale used. So tell me what is it that you see that looks so bad to you? There is veneer on the edges of the cabinets, many Klipsch are raw ply edges all around, the back has veneer that's a bonus, over all it looks like a competent build to me.
I think it was all of the brass screws and washers looking random on the motor board. It just looks sloppy to my eye. On the back they "countersunk" screws without actually using the proper techniques. Just ram them home, as deep as you can with a drill. Nothing looks aligned properly in my opinion.
I'm sure it's functional, but it would bother my OCD.

Which is exactly how solid state radios work. A piece of quartz tuned to a certain frequency.
They can also be made to glow. The process is called triboluminescence and it is easy to do at home if you have two pieces of quartz. Take one in each hand, and practice striking the sides together running the length of the sides. In a dark room, you will see blue sparks appear inside the quartz.
Wintergreen Lifesavers will also do this.
