These are 1979 vintage, so the plain old E networks, new caps, reversed wiring on the now Cornwall B type network. I would like to find a set of 1.5's reasonably priced to make another pair. All the drivers were original, K-22, K-55-V push button, and the K-77 tweeter. The back panel screws were all mismatched, so I bought all new hardware. Another great song if you want to test the bass: Mystic Rhythms, Rush.

I think it should be a brand new, shiny thread to avoid confusion and mixed signals within this thread.

@Treyphan I did have a Homer moment during the rebuild. I had just finished cutting the port, cementing the tube in place, and finished the last bit of egg crate. I buttoned it up, and plugged it into my amp. It sounded very flat. Not good. I was shaking my head, and wondering where I went wrong. I opened the back and rechecked my connections at the crossover. Sure enough, I had forgotten to run the squawker and tweeter negative to positive. I had simply wired it straight, according to the connections shown on the side of the crossover. Swapped the wires around quickly, buttoned it up again, and PRESTO! Needless to say, I felt like a bit of an idiot. [Homer] DOH! [/Homer]

Thanks! I didn't do anything with the tweeters, because I wouldn't get any benefit from upgrading them. I have high pitched tinnitus, with many different discordant notes in either ear, covering a lot of the high end. All from bending down to put air in a motorcycle tire that exploded next to my head, back in the late '80's. The cabinets I picked up were horrible, but the drivers all worked. One side of this particular speaker had an entire corner de-laminated, and it was missing a third of the veneer on one side. I have gone with body filler, re-laminated the corner, filled in all of the chips and missing veneer pieces on every edge. I decided to make these black textured, and it looks decent for such a beater. I was just doing some Blackmore's Night, and the sound is a little awe inspiring. Stevie Ray Vaughn sounds great, too.

@ClaudeJ1 I must, first off, say "Thank you" for the incredible mod, and all the work you put into this project. So, here it is: Thank You! I appreciate you sharing this work with the Klipsch forum, and for the benefit of anyone on the 'Net. I just completed my first Super, and in side by side testing against the stock Heresy, this thing is awesome. I don't have anything in the way of hardware to do "real world" curves, all I have is my aging, tinnitus filled ears. With that being said, the mids and bass are outstanding with this mod. The difference is night and day. I'm listening to some Heart, Jethro Tull, Eagles, Foreigner, Van Morrison, Fleetwood Mac, etc. The sound out of this speaker is crisp, clear, and the bass / midbass gains with the Eminence Deltra Pro 12A are fantastic. I didn't mess with the stock tweeter, because I would not be able to tell any difference there with the hearing issues. I know it produces sound, so that's good. I will mess around with placement, seeing if I can tune it just right. For something bass heavy, I played "Juke Box Hero" and it sounded out of this world. Comparable to the Cornwalls I have heard in the past, maybe a bit better (Probably because these are MINE!) Anyway, for anyone thinking about undertaking this project, I would say that it is well worth the effort and expense. You will not be disappointed.

Any reason why you wouldn't plug the front ports, and do the backward firing ports?

Here's the link to the @ClaudeJ1 Heresy --> Baby Cornwalls modification thread. Basically, you upgrade the woofer to an Eminence Delta Pro 12A (right at $129 each, but there are other options for the woofer as well), rearrange the crossover a bit while replacing the capacitors (which you would want to do anyway), and there is an optional tweeter upgrade. You would add a 4 1/8" port for the bass in the back panel. Then you would do a layer of egg crate sound foam on the inside. It's all really straightforward, and it boosts the midrange quite a bit, plus you get a lot of bonus bass out of the deal. It's a Cornwall in a much smaller cabinet, which is a benefit for apartment dwellers or someone with a small office that wants big sound (this includes me!). I'm using this project to also upgrade them to a 5 way binding post setup, and adding fast blow fuses. This is a good idea here in Central Florida, where we have lightning strikes nearby almost daily, with brownouts and surges. I am in the middle of doing a pair myself, taking my time and enjoying the process!

That's a fantastic looking setup. Are the Heresy speakers in Pompano on eBay yours? I was looking at a pair with a heavy black ring on top of the right speaker...

That's a great price on those. I wish I were closer. Someone will be getting a great deal on these.

If I were you, I would buy this pair of Cornscalas in TN: Damned cheap for what they are. I think you would be happier with these than a simple vanilla pair of Cornwalls.

These were owned by a 90 year old lady that never abused them, and she only listened to gospel on Sundays.

These things appear to be huge! The squawker / tweeter setup reminds me of the engines in antique Moto Guzzi models:

Congratulations on the nice pair! Can we see the sides? Now all we need is a new model (CF-5?) that uses 15" woofer pairs...

Congratulations on finding and repairing the problem!

Where are you located, and how much are you asking for them?

It looks like they have at least a couple of them up for sale. https://www.musicgoround.com/p/939765/used-klipsch-kp-115-sw-speaker-cabinet Used Klipsch KP-115-SW Speaker Cabinet | Speaker Cabinets | Music Go Round www.musicgoround.com Used Klipsch KP-115-SW Speaker Cabinet Music Go Round Lincoln, NE

Here are two auctions I found. These appear to be original, the "W" set has K-55-V squawkers (and seem to be built later into 1981), and the "X" set has K-52-H and are being sold with the original Klipsch box (and seem to be built early in 1982). So it appears to me that the switch occurred between 1981 and 1982, from looking at these photos: 117W496 146X056

He mentions in the auction that the serials are consecutive, but doesn't either show them in a picture, or give them as part of the description. Laziness.

Fantastic information, gentlemen. I really appreciate it! The reason why I asked is this eBay auction for some Heresy 1's: https://www.ebay.com/itm/Klipsch-Heresy-speakers-series-I-consecutive-serial-numbers/163140553557?hash=item25fbef4b55%3Ag%3AzOYAAOSw7VRbQjz-&_sacat=0&_nkw=klipsch+heresy&_from=R40&rt=nc&_trksid=p2507978.m570.l1313.TR7.TRC1.A0.H0.Xklipsch+heresy.TRS1.TSS0

I dug around, but could not seem to find what I was looking for. Unless this is the Heresy 1.5 version that I have seen referenced? Anyway, I was looking for another pair of K-55-V Heresy 1's to use as surround speakers, and I needed a cutoff date so that I am matching the horns.

Free bump. It's one stop shopping at Joe's! Decorators for the front L/R, this for the center, and a rare KG subwoofer.
