Don’t worry. I’m a big boy. Yes I came down hard but the reality is that mods should have never been allowed on the forum. I guess that statement makes me a foe but I can live with that. And anyone can think of me anything they want. Won’t bother me….I promise. Now back to the topic….
Well on a positive note.
Didn't think I would be reading or researching Klipsch Horns today.
Even though recent mod post came up.
It was inspiring enough to want to know more about Klipsch
Have to admit been reading and looking at quite a few models and history most the day now.
Something I probably would never have done.
Being a worldwide forum is has positive potential of introducing people
to the company and products, who might not known it even existed.
Or know the name, but limited knowledge and inspired to view in more detail.
Maybe not everyone can have a Jubilee , but would if they could.
But gives second thought to purchasing a Klipsch system that would work for them.
The negative and positive politics of mods and info are pretty straight forward.
Both sides reactions make sense.
But yah gotta own one to mod one.
And un boxing one just might be a pretty good day.
At least for us, dont know if my neighbors are willing yet to experience Jazz Music
cause they gonna be hearing it , like it or not LOL

It has been said that there is no such thing as bad publicity.
I use a pair of the original Forte's for my TV speakers. They are quite adept at that. I don't use them for music as I have many other diy, and the original Forte utilized a 12" drone to augment the 12" woofer so they tend to struggle at higher levels. I am glad they saw clear in their ways to up the drone to a 15" in future models. I had considered doing the same but since they perform as they do for their chosen assignment, I didn't wish to mess with originality.
I purchased these at a local yard sale from a friend who had them stored upside down in a dark, cool and dry environment for years to counteract sag. The price was right for a friend. I think I still owe that person a favour. His Mrs. was just happy to see them go. So, a favour was done in each direction.
The hand written paper stickers are still with the speakers.

I'm of the modders, with understandable proportionally popular success with PWK's "box that saved the company 60 years ago." I simply ported the real Wood PWK original Heresy Box in the rear (since there was no room in the front) using Klipsch's own Pro Woofer, the K-42. It was motivated after listening to YOU, Chief, (and paying attention) at the U-Jubefest, 2007. The "curve tipping" aspect of a higher BL woofer, to get better midrange and having to port back the lost bass, created a bigger monster than I could have ever imagined, without adequate test gear. So it was all the the other Turkeys and Chickens in the Barnyard that objected to the "no more Mods" rule changes, NOT ME. You know I was totally cool with it and understood, inherently, why it had to be. So, no problemo, amigo! I'm sure everyone here has the same respect for your mad scientist skills as I do. no Bovine Sediment!

I disagree. If the 001 true/false ratios are 50% Yellow Button, and 50% accurate, then no one will know the which is which for sure except for YOU. And you have better things to do than keep up. At least here, things are pre filtered by way of low volume so it's easier for all of us and YOU.
It's also frustrating for the many of us who know better, but can't address the overwhelming number of posts, which appear to be 24/7 based on the TENS of THOUSANDS of posts and counting. There are many Yellow Button perpetrators, but he gets the crown.
But hey as long as he has nothing better to do with his life and can serve as a marketing shill, then why not? There are not enough people offended to make a difference anyhow, so it's all Yellow Button complaints from all of us anyhow and makes no difference in the big picture of life and Klipsch Brand.
Life is good if we all remain positive going forward.
Hi Claude,
I have a pair of Heresy II's that I want to mod to supers. The recommended Eminence woofers' outer diameter is a little too big to fit in the countersunk hole and the midrange horn's flange.
I found a pair of these JBL's open box for a reasonable price. Will they work for this design relative to spec's. The Vas is lower and the BL is higher than the Kappalite. Sensitivity is 96 vs 100.5
I also posted over on the Klipsch forum, I wasn't sure if you still frequented there.

That's a NO. The mod is for a Heresy 1. I don't intend to do further R&D on this (10 years ago with hundreds of happy modders). Get someone with wood working skills and route out a slightly bigger hole if you insist on a II, which is a different animal, just because it has 4 legs........you know the rest.
Hi claude and klipscheads
Well it seems I’ve joined the ranks.
I’m not sure I can be considered a “Klipschead”…maybe more of a “Klipschbumm”…I pulled the trigger on a pair of Industrial LaScala bass bins that came up cheap on fee-bay.
I’ve gotta go pick them up tomorrow about 2 hours away.
Crossing my fingers there’s no serious issues with them. There were no internal pics and I did notice some screws driven up through the mouth that look to be holding the dog house cover on the bottom. I hope there’s nothing ugly like stripped holes in the motor board.
They look pretty solid in the listing pics. Mostly scuffing, scratching and chips in the paint. Maybe a few chewed up corners.
If they work out for me I’ll figure out a way to make them prettier for home use.
The seller doesn’t know a lot about them. He got them in a purchase of a larger group of items.
He had K-43 drivers as well that were pulled…two pairs for sale. I wasn’t sure of their condition and said I’d like to look at them when I pick these up. The K-43 listing’s disappeared…not sure if he sold them or is waiting to see if I take them.
I have a pair if reconed Electrovoice EVM15B I can try in them that I originally bought to build either a conical mid bass or Quarter Pie…which I just couldn’t find the time for.
If that doesn’t work well I can always look into the Eminence Kappas, Crites etc.
The idea is to finally get a bass horn up and working in my new house that I can try various “heads” on.
I’ve got a few I’ve hoarded over the last several years including some 511B, Edgar 350Hz round wood Tractrix, Oris 200 some custom conicals and some big B-52 horns I picked up on clearance at Parts express.
I’m not sure what drivers will work best I’ve got some Dukane 5A540, Radian760pbneo, Dynavox D54 and even some BMS 4590 coaxials. Plenty of high efficiency wide bands as well. A two way may be the easiest way to start.
The LaScala bass bins will be driven by Hypex FA502 amps which will hopefully allow me the flexibility to adjust things well enough to meet up with what’s on top.
I have a pair of the hypex, so they’ll even be the flexibility of a second channel on each bin if I decide to go three or four way and add a mid-bass.
Already thinking about the ported reflex base modification tothe LaScala for the possibility of some added bass extension.
Looks like an exciting time ahead.

Not sure what your expectations are but a LaScala is not a bass bin. They start to roll at about 140 Hz and in a multi way systen should be crossed at around 90 Hz. to a woofer. At 50 Hz. their response is about the same as a Heresy. Just so you know.
A number of us have done variations on the DJK ported LaScala, using the PRV Audio WG45-50 horn and their D2200PH driver and assorted tweeters and detailed the builds either here or at Audio Karma. A couple were top-ported and extend to 35-32Hz; I built a set with a 15” passive radiator in lieu of a port, that extends 23Hz - 20kHz -/+ 3dB: https://www.diyaudio.com/community/threads/lascalus-a-horn-loaded-lascala-chorus-hybrid.403921/
In my opinion, they sound better than a Klipschorn and are a lot more flexible with positioning.
Hi Moray
I’ve no direct experience with the LaScala.
I didn’t mean to imply that these were meant to be a complete bass solution.
I’ve read enough about them to know they don’t go as low as quiet a few would like them to.
That’s why I mentioned the ported reflex modification for them. I can always try it to see if I can wring a little more out on the bottom end.
I’m hoping the Hypex amps will help in that area as well as the top end where I need the LaScala to hand off.
My experience with various front and back loaded horns and wide bands in the past was always focused on support below 150-300Hz.
I do have a Jamo subwoofer that has been a big help in the past below 75Hz.
P.S. Dave Ault's tweeters have also been on my radar for a while now.

With a pair of 4” x 7” ports, either below or in the upper horn enclosure, you can easily get to at least 35Hz; I don’t have any direct experience, but I’ve read that ports as long as 11” will enable even more extension, but it also sounds “boomy”.
My clones used Dayton Audio 15” passive radiators with no added weight and JBL 2226H woofers and a cabinet volume of around 9 cubic feet. It had simulated to 28Hz, but in actual practice, I got down to 23Hz. & I’ve sold my subwoofers except for a small one in my home theater setup.

A Heresy does not have a 7 db peak at 140 Hz.
The HORN portion of a LaScala cuts off at 104 Hz. the rest is a closed box in a really tight "corner" in the cabinet that gets further Augmented by a room corner. The Peavey FH-1 is a far flatter, better built, MIDbass Horn. They both need subwoofers below 80 Hz.
I’m definitely looking forward to getting them up and running so I can experiment and see for myself what’s possible.
I’ve been finding all kinds of threads with information…some also with missing content…but for the most part its out there and accessible.
These are the buyout horns I got from Parts Express a few years back:
https://www.parts-express.com/TE-8180-1-Horn-22.5-x-10-1-3-8-18-TPI-299-2306?quantity=1
I was originally going to try and build a MEH from them…might still try. I modified them by removing the threaded throat and building my own flanges out of PVC so I could mount my Dukane 5A540.
Some test sweeps with my mic and REW showed a lot of potential…very good extension.
I also built adapters for my 511B horns, but haven’t taken any measurements yet.

Things went well today with the pickup.
The horns are very solid and in overall very good condition for their age (70s).
I don’t think it will take too much work to get them smooth and ready for some fresh paint or some other finish to pretty them up.
The seller also still had the 2 pair of K-43 drivers.
After looking them over and measuring them with my DMM it became apparent which drivers were in better condition and belonged together.
The pair I was interested in was cleaner overall and measured 3.4 and 3.5 Ohms. I suspect they might be recones.
The only real issue I found was one driver had a section of gasket that has partially delaminated. Not a big deal to fix with a replacement.
We talked about price. I decided to take them just so I could have a set in case I ever pursue a build that follows the original design more closely with a passive crossover.

K-43's are superior woofers for LaScalas. You should just build a pair of Anarchy Tapped Horn Subs to place underneath with the cheapest subwoofer amp from parts express (25 W) I even used a pair of them to driver MWM's. LOL. Flat from 25-100 hz. and they will amaze you for their small size. They will also raise up your tweeter by 7" if you place them underneath with the mouth towards the back wall, making it invisible.
Hi Claude
I’m glad for any suggestions you have to offer.
I’ve spent a lot of time on different forums reading about your various horn adventures. You have a lot of experience I can learn from.
I gather your talking about these:
https://www.avsforum.com/threads/reed-exodus-anarchy-25hz-tapped-horn.1238398/
I’d not really considered what my final sub solution might be…or that it could just pickup where the LaScala left off.
I guess I got wrapped up in the idea of trying to make the LaScala do more.
Interesting idea. I could just leave the LaScala LF cabinet as is.
I’ve wandered in and out of tapped horn threads for years and thought to myself “some day”.
I haven’t read all the details, but it looks like a fairly old (albeit good) design that would be fairly easy to execute.
First hurdle that pops up…are there drivers still available?
The only Google hit that popped up for me was this:
https://www.diysoundgroup.com/speaker-parts.html
Closest thing I see is some 7” drivers that are out of stock.
It’s not clear if they are even the correct drivers.
I’ll have to do some more searching to see if there is anything available that is compatible with the design.
Using the K-43 in the LaScala LF horns pushes my thoughts more in the direction of what to pick to try on top first, and whether I want to be able to use some kind of passive crossover there at all.
As I said, I’ve hoarded a bunch of different horns. I’m not sure any of them are ideal.
Picking one to integrate with the LaScala LF successfully for a beginner like me should probably be kept as simple as possible.
