How much of High End Audio is Horn Speakers?

To answer the OP’s question, years ago, Klipsch did have name cache with audiophiles. (about 45 years ago) That eroded as boutique American brands appeared as well as the great British brands. At that point, the image of Klipsch became less exclusive, because they expanded beyond the Heritage range to less expensive models as well as moving into home theatre.

Meanwhile, they still produced a few of the Heritage models, and steadily improved them. Today, with the renewed interest in the improved Heritage models due to the enthusiastic professional and consumer reviews, I think that the Klipsch image has really regained some of its former luster and prestige.

I have owned Khorns, Cornwalls and still use Epic CF 4’s as my main speakers,. This past weekend in fact, I bought a pair of KG 3.2 off of Craigslist for $150.00 for my shed, and they sound amazingly good.

I have a pair of JBL 4349’s that use a wave guide for the high frequency driver.  Essentially a horn.  I don’t think I’d ever go back to a non-horn speaker.  What a treat to listen to.  They project and fill my listening room extremely well.

Klipsch have good potential ,for the inner Xover is the weak link, even their latest model  the Xover parts are very cheap and not even a average level of 6-7 

15  being the best theXover being the ❤️ or 🧠  of the speaker  ,this is  not a isolated incident even in $15 k speakers  None have top parts 

go to Humble homemade Hifi Capacitor test , you will see what I mean

 Duelund are the most expensive and at top level , And byw all Copper foils are the best poly caps are sprayed metal on plastic and paper 

Jupiter, Milflex ,VH audio Copperfoil are also very good each sounds a bit different ,

resistors  Mundorfs new Copperfoil resistors are the most detailed , path audio is a close second a bit warmer ,  many use cheap Solen caps, or from Taiwan ,even in Harbeth ,revel and many others ,even Wilson ,they bough5 Rel caps kthey are better then average but not near the top.I told the engineers at Marten Logan on their flagship $80 k speaker mid grade Mundorf Evo capacitors Really ,a $20 cap ,at least put in Mundorfs best silver gold oil which are very good , ifyou can’t see many companies cheat ,also gold brass connectors ,when copper gold is 3 x less resistive ,more conductive , I am just making a point after modding Xovers for 20 years now.

Here's the deal... no speaker is perfect each type has strengths and weaknesses (conventual sealed box & vented, electrostatic, ribbon, horn, and a few others).  There are so many types due to people's preferences between speed, dynamics, imaging, resolution, tonal color, frequency range, AND cost.

I have made the journey over the years between several types and top brands and have landed back with horn speakers for the last 3 years and continue to love them.  Do not be detoured by what others preferences are or brand snobs. 

This hobby is a journey, enjoy the ride and discovery along the way.

It is clear that Klipsch are special, you either love them or not, I'm a definite not despite trying to do so for 50 years.
