ALK Universal crossover network

The original "ALK Universal" replacement crossover network for the Klipschorn, La Scala and Belle Klipsch as been reimplemented to create an affordable option for nearly any Klipsch based 3-way loudspeaker.

High cost is no longer a reason to turn the clock on your Klipsch back to 1975 with a newly built A or AA "Clone" from other vendors, when you can turn it forward with a modern design!

Introducing...

The Universal Economy

The "CSW"

(CornScala-Wall)

An economy network for almost any 3-way loudspeaker.

Note: The option to upgrade the capacitors to other brands is NOT offered. The Cornscala-Wall is an economy network. It represents the best bang-for-the-buck as is. If more performance is desired the ap12-xxx and ap15-xxx sets are suggested. Read more about this

Frequently asked and related questions about the original version:

1-Why is this network called the "Universal"?

2-Can I change the woofer / squawker crossover up higher to allow me to replace the K55 driver with a better one since most will only go down to 500 or 800 Hz?

Here's the answer to both questions: Look here

The new CSW-450

The CSW-450 network is an upgraded version of the CSW network that is ideal for the Klipsch LaScala or DIY CornScalas. It adds a second order (12 dB / octave) woofer to squawker crossover section at 450 Hz to the CSW to give you a better performance at a modest price. It is an ALK design but will be available soon from AmpsAndSound .


ALK Engineering upgrade for the Klipsch Forte I and Forte II balancing network

(The development of the Forte I network was described as it was being done on the Klipsch forum. The design is there for the DIYers)

(The Chorus models are NOT compatible.)

Titanium replacement diaphragms for the Forte tweeter are compatible with the Forte networks. ALK has no opinion about their value. It is your choice if you choose to install them.

Special option: The transformer on the stock Forte crossovers can be reused on the new network. If you remove the old networks along with the interconnect cable and return them to ALK you can deduct $48.00 from the price and I will attach the interconnect cables to the new network for you. The down side is that you will be without your speakers for about a week. What remains of the old network is useless and is donated to the trash man!
