Volti Crossover Networks

So Beautiful, You May Want To
Put Them On Top Of Your Speakers!

Speaker crossovers perform an important function for our speakers to work properly.  They divide the full-range signal from the amplifier into three limited-range signals, one for the woofer, one for the midrange driver and one for the tweeter.  They are also providing a significant role in the overal voicing of the speaker - either consciously or unconsciously by the designer.

Speaker designers who are consciously using the crossover to 'shape' and 'bend' the signals are doing so by testing and measuring as a starting point, and then they listen to music through the system, while making changes to the crossover components.  Speaker designers who are unconsciously creating a voicing of a speaker are using testing and measuring only, making decisions based on what is shown on a computer screen.

These are both valid approaches to speaker design and which you prefer rests only on what you like for a sound - because all things in this audio hobby of ours is subjective.  No matter how often, or with how much voracity the 'measurement first' designers shout out the proverbial window to the world that their way is the only way, it still comes down to what you like.

I'll tell you what I like.  When I sit down in front of my system, I want the music to be effortless, natural, and as real as possible.   I want my system to sound like music, and not like a hifi system.  I want the system to disappear.  I don't want any part of the system to draw attention to itself.  I don't want to think about the system when I sit down to listen to music.   I simply want music, floating in front of me to enjoy.

Volti Audio crossovers are not only beautifully built, but they will also help you get closer to the goal of enjoying the music exactly as the artists intended.  They will help you reach that goal of having the music floating in front of you, separated from the equipment that is reproducing it - as effortless, natural, and real as possible.

V-Trac Khorn Networks (VTK400)

I prefer a very simple electronic chain from source to speaker in my own system, and I have the same desire for my passive crossover networks.   I don't want a lot of components between me and the music, so my crossover networks are very simple in their design, much like the original Klipsch "A" networks back in their day.  The Klipsch "A" crossover network was the simplest one ever developed for the Khorn by Mr. Klipsch, and it was his preferred network for his own Khorns.

Some designers prefer to use crossovers that provide steep slopes between components (called Extreme Slope Crossovers).  Meaning that the tweeter is cut off very sharply to the midrange and the midrange very sharply to the tweeter, not allowing much, if any 'mix' between the two.  Other designers prefer to have a mix of the tweeter and midrange at the crossover point - not cutting them off sharply.  Both are valid approaches, and both sound quite different from one another.  Which approach you prefer will rest solely on what you like for a sound, because everything in audio is subjective.

I've heard extreme-slope crossovers on my own Khorns, with their multitude of components all crammed together on a board, controlling and manipulating the signals with great effect.  Some people will tell you that this is a more technically correct approach, but I found the sound to be more like a machine - dead and lifeless and boring in comparison to a simpler crossover with fewer components.  I much prefer the sound of simple crossover networks in my Khorns.  It is simply less intrusive and allows the music to flow naturally.

With the VTK crossovers, you will appreciate the simplicity of the design, and how they allow the music to flow freely and naturally, with a minimal number of very high quality components, doing only the job that is required.

The VTK400 has everything you need in a crossover for your
V-Trac upgraded Khorns, and nothing you don't need.

One of the nice features of these networks is that there are no barrier strips - screw terminal strips.   If you've got large speaker wires going to your speakers, you'll really like the fact that you can make a nice connection through the heavy-duty binding posts, rather than those tiny screws you normally have to hook to.  Notice how the front of the network board is angled back slightly to make plugging in a little easier.  The component hookups are done with brass binding screws that are threaded into inserts mounted in the wood.  Even the inserts are brass so the connections are very good.  

Hooking up the drivers to the crossovers is intuitive.  Hookups for tweeters are on the backs of the board, the midrange hookup is set to the left of the input in front of the autotransformer, and woofer connections are made to the right of the input in front of the woofer inductors.

Using this network is a pleasure.  You will finally have control over the voicing of the midrange and upper-bass in your Khorns.  There are so many different factors that influence the sound of your Khorns, especially in the critical upper-bass range.  Size of room, height of ceiling, less than optimal corners, volume levels, downstream components, etc...  With the VTK networks, you can adjust the midrange output in conjunction with the upper-bass by selecting different hookup points on the board.  There are many different combinations that you can choose to provide just the right voicing for your system.  

VTK400 Pair - $979, single - $540

V-Trac Belle Networks (VTB400)

Same design and specifications as the VTK400 networks, with slight changes to the components for better voicing with the Belle Klipsch speakers.

The networks also include a tweeter attenuation circuit built in.  This circuit is easily removable if you wish to have full output from the tweeter.

VTB400 Pair - $1,050, single - $570

The VTB400 networks are made to order and will require a 30 day lead time
