RIP Larry.
As one of the “Knights of the Round Table”, Larry was a real asset to this forum and the loss is another chapter in the passing of an era.

I have an extra single Faital Pro HF104 tweeter compression driver - new, never used. 108db sensitivity, 80 watts, 8ohms. Neo magnet. Standard tweeter horn mounting.
Bought for extensive component testing years ago, but this one got left out completely.
$110 shipped in the US, payment through PayPal.
Thank you.

I have one pair of Faital Pro HF108 tweeter compression drivers. Never used, 8ohm, 109db sensitivity, 120 watts handling. Neo magnet. Mounting is standard and same as the lower HF line, B&C hf compression drivers, etc.
These are a top of line, ultra sensitive, high power tweeter drivers that are usually matched with a very high end system on a number of available horns.
Great for high end Klipschorn mods or use in professional custom builds with Klipsch professional series setups.
I purchased these several years ago and used one in about 30 minutes worth of controlled tests, then put back in the original box.
$235 shipped US for the pair with PayPal.
Thank you.

SOLD
Pair of Eminence APT-200 Super Tweeters for sale . Virtually no use as new. One was used in testing for a couple of hours.
These 8ohm tweeters have the large bi-radial lenses and deliver ~ 103db sensitivity with frequency range of 3500hz-20khz. Can be crossed as low as 3500hz.
Many use these as set top tweeters on top of Klipschorns or LaScalas.
These are pretty good sounding tweeters at any price and a real bargain in my opinion.
$70 plus shipping for the pair via PayPal. SOLD
Thanks!

Looking to build a 60” version of Claude’s outstanding quarter pie (half a Klipsch MWM) and don’t see his thread here. Am I missing it? Does anyone have the plans for the 60” version?
Thank you in advance.

Langston - outstanding contribution to this forum!
autoformers vs resistors - efficacy? Power loss, distortion, cost, etc.
I did a fair amount of testing years ago on a number of things, but only one involving the question of resistors - and then a very simple test. I built two identical crossovers designed to deliver a 400hz midrange cross point - but gave one the swamping resistor autoformer treatment, (with corresponding capacitor) and the other no swamping resistor, (with corresponding capacitor).
Running controlled full test sweeps on Klipschorns with all drivers running on the full network with amplifier setting locked, there was a significant difference, maybe 3db in output from the speaker between the two crossovers across the entire midrange. Very, very little impact response variance was measured. In any event, the swamping resistor crossover produced about 3db less output across the range. At the time, I laughed to myself because Bob Crites, a consummate gentlemen in every respect, described the difference as sounding like “someone put a sock in it.” Of course the issues raised by this thread are much broader than the question of resistors used for impedance swamping.
In any event, given the migration over the decades of apparently all speaker manufacturers, including Klipsch, to the full resistor-based attenuation approach, I too have wanted to get more insight and understanding of the potential advantages and disadvantages.
One thing is clear to me and to Roy’s credit, Klipsch heritage speakers with the latest passive, steep slope, resistor-based networks have never sounded better I’m my opinion.
Great thread!

I have one Crites type A crossover for sale. I purchased this new about 7-8 years ago while testing various crossovers and drivers. Probably has 5-6 hours of use from measurement and listening testing. So, this is several years old, but basically new. Kept in storage, but I’m cleaning out some extra parts. This is the same crossover with Sonicaps they now sell as the “Gold” edition.
Pretty straightforward item, but feel free to shoot questions.
$175 shipped with PayPal. SOLD
Thanks.

One original k-700 metal horn available. Great condition.
$50 plus $15 shipping.

Bump - rare original early k-55 still available.

Still available.

@mboxler - excellent work and observations. While the midrange and tweeter issues between network and driver variations are more well known, the woofer to midrange transition in a KLIPSCHORN is less understood. Your woofer polarity swap with a gentle 6db slope network is a great example.
It would be great to get Chief Bonehead’s insight on that issue.

For more than twenty years I’ve belonged to these Klipsch forums. I presently own four pairs of Klipsch speakers. Before and while being a forum member I’ve owned Khorns, Cornwalls, La Scalas, Belles, and innumerable Heresy variants.
I’ve restored La Scalas and Heresys for the band rooms of a local high school and a local middle school. Thousands of young musicians have been exposed to the clean low distortion high output sound of Klipsch.
None of that would have happened without the Klipsch forums. More important, none of it would have happened if the forums then had been like the forums are now. Apparently, it’s a sacrilege that I refreshed the La Salas’ crossovers with parts that we’re not from Klipsch, or that I modified the bass bins with reinforcement to address a known sidewall flexing issue.
I met many friends through the forum. My DIY tapped horn subs were brought to my attention by a post from Carl @CECAA850. My “Supered” HIPs were modified into existence with the assistance of Claude @ClaudeJ1. Countless other friendships started here. I sold a Harman Kardon receiver to Bruce @Marvel. Another member, whose name escapes me but the gratitude remains, sent a Dual turntable to play 78s. Sadly, many of those members have drifted away from this platform.
I just donated $60 to the Klipsch Heritage Museum Association to pay it forward for the kindness of @billybob, who sent me an equalizer so that I could play 78s. To the best of my knowledge, Klipsch does not make such equalizers.
I’ve been an ambassador for Klipsch since the 70s . The forum in the days when the mention of a non-Klipsch product was tolerated was a welcoming place. Unfortunately, that is no longer true.
I’ve lost track of the number of Klipsch products friends and family have chosen upon my recommendations. Clearly Klipsch can do as it chooses with its forums. If the mention of things other than Klipsch is precluded, then my interest in following the Klipsch forums is greatly diminished. The phrase, “biting of your nose to spite your face” comes to mind.
Is Klipsch in danger of losing more business by driving away me and others, or by allowing the mention of things non-Klipsch? I suggest alienating long term members is more problematic than any perceived “competition” from the mention of non-Klipsch modifications. Ultimately, it’s up to Roy @Chief bonehead, and others at Klipsch, whether to allow the forum to return to its former collegial atmosphere or to continue on the off-putting parochial path it appears to prefer.
Change is inevitable and usually resisted. In my opinion, unnecessary changes have made this a less desirable neighborhood. It does no good to tell me and others that we’re wrong to feel alienated. Whether or not that is the intention, that is how I feel
Peace!

After close inspection of the installed driver pictured, it does appear to have been labeled as a K 55. I’ve also noticed that this rare driver’s diameter is bigger and the throat casting of the rare K 55 is clearly different from the MA-25 and much closer to the SAHF, but likely intended to replace both. This driver is a University build, albeit likely a test or transitional model using the basic design elements of the SAHF, and built specifically for Klipsch prior to the atlas k55 that followed it. Unfortunately, I cannot find any additional information.
-
Great pic of the rare driver in a speaker and very helpful Looks like a ‘59-‘60 heresy. Can’t read any designation on it, but it is clearly an example of what I’m selling and clearly a different midrange driver than the earlier SAHF or MA-25. All from University I believe. Horn looks like the first Heresey , and Cornwall, and looking back, I believe I was given reference to the first Cornwalls before they came up with the k-600 and atlas k-55.

And here is another of the traditional University midrange driver’s that most of us are familiar with:
This is the SAHF 30 watt midrange driver used for several years on the 1950’s Klipschorns. This example is one of mine, from one of my 1950’s Klipschorns. Note the typical University screw wire pins, the L1 and L2 pin designations and the same Allen head pins used for diaphragm access.
On other Klipsch models, variations, like the MA-25, with the same shape and style we’re used. Of course the University driver I’m selling isn’t either of these University models.
I would have to believe that the Klipsch museum must have one or two of these mounted in their original speakers. Anyone?
-
Let me provide more help on this. That is probably true for the atlas k-55, but this is a University transition k-55 used in the last 1950’s, following the University SAHF driver, but before the now familiar Atlas k-55 v drivers from the early 60’s on. I am unsure though on how many or which Klipsch models featured them and for how long.
-
I have a very rare, working k-55 midrange driver for sale. These were used on some models in the last 50’s, and very early 60’s I believe. I’ve never paid much attention to this, so someone on this forum may have a lot if additional perspective and information. Faint identification on this one as a k-55, other rare examples of this are also labeled as Klipsch k-55.
Update: Apparently this driver was an OEM University build as a transitional model using the basic design elements of the SAHF, and built specifically for Klipsch prior to the now familiar atlas k55 that quickly followed it. An interesting piece of Klipsch history.
DCR: 12.5
Thank you.
