Here in this section, I am going to show how to replace the original crossover in a Forte II speaker with our B & K Sound Forte II crossover. With minor differences, this is the way that you would change out the crossovers in many of the Klipsch speakers including the:

Designing a crossover network, even if you have the specification sheets on every component is not easy. It requires that I have the COMPLETE speaker, in the cabinet, for testing. Here is a Klipsch forum thread describing the development of the network for the Klipsh Forte I. It should show you what is involved.
In all of these cases, you will need to remove the old crossovers (usually from the back of the input terminal cup) and install the new crossovers in a new location. For this speaker and others with a passive radiator, removing the passive radiator will give access to the area where the new crossover can be mounted. For speakers without a passive radiator, removal of the woofer may be the way to gain access to this mounting area.
Forte II Specific Instructions:
Remove the Passive radiator from the back of the speaker.
After removing the passive radiator, put it in a safe place to prevent damage to the radiator.
A look inside the back with the passive radiator removed.
Now remove the screws holding the input terminal cup.
Here is a look at the original crossover from the inside.

Input terminal cup with crossover outside.
Three pairs of wires (in the case of this speaker) go from the crossover to the drivers. You will want to notice which wire is positive and to which terminal of the drivers that positive wire hooks up to. Each pair of wires have one black and one colored wire (red, green and yellow in this case). The colored wires are connected to the positive terminals of the drivers. It is good to pay attention now to make sure you know which is the positive terminal on each driver.

Now we work on getting the original crossover removed from the input terminal cup.
Remove the two screws holding the autotransformer. We need to move it out of the way first to have access to one of the screws that holds down the crossover circuit board.
Now we can remove the screws that hold the circuit board in place.
Time to place the new replacement crossover in position. For this speaker, the perfect place will be mounted flat on the bottom of the cabinet. Velcro tabs will hold the crossover in place.
Notice that now we can remove the crossover and place it right back on the velcro tabs. Microsoft lync 2013 client for mac.
Bring the input wires from the new crossover out through the hole for the input terminal and connect them to the input terminals.
As we connect the wires from the new crossovers to the drivers, you may need to close up the connectors a bit to get a snug fit on the driver terminals.
Route all the driver wires to the drivers and connect them.
Re-install the input terminal cup.
Connect and install the tweeter.
Re-install the passive radiator.
The biggest improvement in the sound quality of the Klipsch Heritage series is to replace the stock K400 or K500 midrange 'squawker' horn with a better one. At this time the choices are very limited. I know of only two good options. The first, if you are up to some woodworking, is the Eliptrac 400 2-inch elliptic wood tractrix. This horn will require a 2-inch driver or an adaptor to continue using the Klipsch K55 driver.
Enlarge The picture at the left shows the finished Eliptrac 400 horn kit installed in a frame for the Klipschorn. The frame must be constructed to allow the tweeter to be mounted alongside the horn. The frame is NOT currently available. You need to build it. Here's the plans: Enlarge
The horn kit comes like this:
Here are the actual assembly instructions for the kit.
Email Dave at: [email protected] for pricing and to order.
The Eliptrac 400 is a 2-Inch horn. This adaptor from Parts Express will allow the stock K55 driver to be used.

The venerable old Altec 811b and 511b 'Voice of the Theater' horns are no longer made but can be found on eBay. These are 1-inch horns and will require an inexpensive adaptor to use the Klipsch K55V squawker driver. They are MUCH better sounding horns than the stock horn!
The least expensive option is to add damping material to the OUTSIDE of the midrange horn. You wouldn't think this would make any difference, but it DOES! The material is stick on asphalt sheets available from automotive parts stores like Pep Boys or AutoZone. The best known brand is called Dynamat. It helps on any horn, even the Altec VOT horns.

The Edgar horns sound much better then the stock Klipsch squawker horns.
The program is a Windows 'console' program that will run on any version of Windows by simply double-clicking on it from Windows explorer. You can download it here:
TRACHORN.EXE, Version 1.8b for 32 or 64 bit Windows
Trachorn.exe program has several command line options.
- Enter a new length in Inches to see the effect on the horn throat. It's not good for anything practical as you want a perfectly square throat.
(S)-Square adjusts the length to return to a square throat.(F)-File generates a text file (trachorn.txt) that tabulates thedimension X and W/2 dimensions describing the curved sides and dimensions required to make the assembly jig.(M)-Macro will generate a macro file for either (A)-AutoDADD or (G)-General cad to make a precise template of the curved sides.(Enter) will exit the program.
