It All Matters

I've been offering these upgrade parts for Khorns and Belles for a very long time now, and it has become obvious to me that my customers who have purchased the entire upgrade package all at one time are the most satisfied customers I have.  There's good reason for this.  The Volti Audio Klipsch Upgrades system is a complete engineered system that depends on each and every part to contribute to the whole.

In the past I've offered my Klipsch Upgrades parts A La Carte, as a way to help some of my customers who are on a more restricted budget at least make some improvement to their Khorns and Belles.

Due to changes in my business (increased Volti Audio speaker sales), I am slowly moving away from the A La Carte business in favor of providing complete upgrade packages to my customers.   I'll continue to do my best to provide parts when available, especially the New VTK crossovers, but please understand, I may not be able to always accommodate your requests for individual parts in the future.

I strongly recommend that you purchase the entire engineered upgrade package all at one time, as opposed to purchasing each element of the system individually over time.  The individual parts of the system all enhance the end result in some important way, and if you only choose to purchase one or two of the parts, you simply will not realize the benefit of having the whole system in your Khorns.  You do want all of these upgrades - you deserve to have all of the upgrades - you really should do it sooner rather than later, because when you hear the difference this system makes in the quality of sound from your speakers, you'll wish you had done it many years ago.

I know there are some less expensive options available to upgrade your Khorn speakers, but I'm simply not interested in, nor do I have the time to try and compete with the cheaper stuff.  The Volti Audio Klipsch Upgrades are the very best available and that's what I enjoy offering to my customers.

You'll not find a better engineered combination of replacement components for your Khorn speakers than the Volti Audio Klipsch Upgrades.  You will also not find a better sounding setup for the Khorns.  This is the best sound you can get from these iconic beauties.

Even compared to brand new stock Klipschorns, it's not a fair fight.  The sound quality of the Volti Audio Klipsch Upgrades package in an old pair of Khorn cabinets completely embarrasses brand new stock Klipschorns.

It's not that Klipsch is incapable of making a better sounding Khorn, because they certainly have the talent and resources to do it.  They choose different approaches to speaker design and construction than I do based on their corporate structure, huge overhead expenses, and VOXX shareholder profits.  I'm fine with the way Klipsch operates and I think it makes a lot of sense.  They are very good at what they do.  But things are very different over here at Volti Audio.

Klipsch is a very successful business operating on a very large scale.  When you break it down to the level that I'm working at - a very small company working with a very low overhead and no shareholders, it becomes more about the parts quality and what actually sounds better.  More like how you would do it for yourself if you could.  

Look, I'm just going to be blunt here, you can't use midrange drivers made in China that cost twenty bucks each and put those on a midrange horn designed in the early 1950's with a throat size barely the size of your pinky finger and expect to be able to complete with the sound quality of the Volti Audio hand-built, wooden, midrange horn with a full two-inch diameter throat and a top quality, Italian or German-made midrange compression driver attached to it.  There simply is no comparison.  It's not even close.  It's exact opposite ends of the quality spectrum.

If you want something better . . . . . significantly better, that's where Volti Audio comes in.

If you can afford it, you really should just buy the complete upgrade package.  Trust me, you'll spend the money one time and you'll be enjoying the very best sound you can get from your Khorns for the rest of your life.

Here's a rundown of the individual components that make up the Volti Audio complete upgrades package for a pair of Klipsch Khorn speakers.   Click on the underlined links to go to the individual component webpages, where you'll find more detailed information about each piece.

V-TracII Midrange Horns

The stock Khorn midrange horn (all models) is a perfect horn to use if you want to illustrate what a 'honky' horn sounds like.  The tiny (11/16" diameter inlet), and long throat of this horn, is responsible for creating colorations and a constricted sound to the midrange that is completely unacceptable by modern horn speaker standards, and also completely fixable with the upgrade to the Volti Audio Khorn V-TracII Horns.

Open up, warm up, and smooth out the midrange with the Volti Audio V-TracII horn.  You'll be amazed at how this midrange horn improves everything about your Khorns - even the upper bass out of the bass horn takes on better definition and detail.


Khorn V-TracII Horn

New Volti Tweeters

I'm always on the hunt for great sounding high-sensitivity tweeters.  Choices are limited.  Most high-sensitivity tweeters are made for P.A. use and they have that irritating 6Khz - 8Khz peak that is a hallmark of P.A. tweeters.  That may work for Klipsch, but it doesn't work for me.   For years I offered my customers the Beyma CP-25 tweeter, and even though it was less than perfect, it offered us a vast improvement in smoothness and bandwidth as compared to the old K77 tweeters that came with our Khorns.  They were lush sounding and integrated nicely with the V-Trac midrange horns.

I've recently discovered a very nice combination of driver and horn lens that is significantly better than the Beyma CP25.  With smoother response and much higher extension, this New Volti tweeter sounds wonderful.


Pictures forthcoming.  This tweeter update is happening 11/20/2023 and all upgrade kits from this point forward will have the New Volti tweeter in place of the old Beyma CP25.

VTK400 Crossovers

The VTK400 Crossover is a Greg Roberts design that offers a similar design philosophy to Mr. Klipsch's Type-A network, but with much higher quality parts.  It is a crossover that is carefully tuned to correctly 'balance' the components of the system.  By using fewer parts of exceptionally high quality, the purity of the signal coming into the speaker is maintained as it passes through the crossover and to the individual drivers of the speaker.  It is a pure, 'do no harm' approach to system design that allows the music to flow naturally and effortlessly.

The Volti Audio VTK400 Crossover is the best sounding crossover I've ever designed for the Klipsch Khorn.


Midrange Drivers

A very important part of the Volti Audio Khorn Upgrade package is to replace those old K55 midrange drivers (originally designed as firehouse station siren drivers - yes really), with modern, very high quality, 2" outlet midrange compresson drivers.  I offer two different choices, both chosen because of their diaphragms made of natural materials like paper and/or phenolic material, as opposed to metal.  In combination with the big, 2"-throat, wooden, hand-built V-Trac midrange horns, they are nothing short of amazing in terms of providing that effortless, full, rich, spacious midrange sound that Volti Audio is known for.   That 'midrange' that makes you believe you could walk into the soundstage and shake hands with the saxaphone player!

B&C DCM50 $1,200/pr

BMS 4592-MID $1,900/pr

Woofers and Wiring

Are the woofers in your Khorns the original ones?  Are they K33 4-ohm woofers?  Unless you bought your Khorns new and you know that the woofers have never been replaced, I recommend you have a look inside to make sure they are the correct woofers.  It is common for people to change out the original woofers for something that is not correctly specified and the performance of the bass horn suffers because of it.  The Khorn bass horn requires a properly specified woofer to work properly.

So you've opened them up and verified that they have Klipsch K33 4-ohm woofers.  Great.  Those woofers can last for decades.   But if they are very old, how do you know if they are 100%?  It's hard to tell, which is why you might consider replacing them with new woofers.

If you decide to do that, the Crites 1526C woofer is the one you want.  It is designed and manufactured to be an exact replacement.

Will you get a big improvement by doing this?   Honestly it's hard to say.  Maybe not, because if you have two good working original K33 woofers in your Khorns, the Crites woofers offer very little improvement, if any noticeable improvement.  But if your 40 year old woofers are worn out, you will probably notice a nice improvement by changing them out.  In the big scheme of things, it's a $350 investment in new parts that will compliment the rest of the $4,500 parts you are buying.  It's a bit of a risk I guess, but at least it's only a $350 risk, and in the end you will have peace of mind knowing that you're getting the highest level of performance from your bass horns.

Crites Woofers

It really wouldn't make much sense to upgrade all these parts and not change out the wiring now would it?  Of course not, which is why we offer two different options for internal wiring.

Klipsch Belle Upgrades

Hi Klipsch Belle owners, thank you for scrolling down here.  I used to have a separate webpage just for the Belle upgrades, and it was nearly identical to the Klipschorn upgrades webpage.  But I've simplified things and just have this one webpage.  I have the same exact upgrades listed above for the Klipschorn available for your Belle speakers.  The only difference is the Belle V-Trac horn is slightly smaller than the K-horn V-Trac horn so that it will fit inside the tophat of your speakers.  I think the improvement in sound quality when upgrading Belle speakers is even greater than with Khorns due to the smaller midrange horn found in the Belle.  Wanna turn your Belle speakers into world-class horn speakers?  You're at the right place!
