Announcement:

I have decided to retire from full time crossover network building. I will accept no new formal orders.

However:

Having built so may of these over the years, I have a good idea of the most popular models. I expect to build some of these models occasionally and offer them for sale. You will find these and other items on the FOR SALE page


The economical upgrade for any of the Klipsch heritage series speakers.

Here's the latest ALK Universal network in it's new Universal III form. These will soon be available from Michael Crites of Crites Speakers built to my specifications. They will look a little different but the performance will be as good as ever!

Here are the details direct from Crites Speakers: [ Take me there! ]

Interested? Michael is making a list. Email him at critessales@gmail.com


Between 2000 and 2021 I have built over 2200 crossover networks. I am burned out!

I am 75 years old and anxious to reduce my work load and do other things.

Parts, especially iron core inductors, have become nearly impossible to get. Substitutions have been just as difficult to identify and obtain.

Note that my telephone answering machine has been turned off and I will usually not answer. Your best bet to contact me is by email (ak@alkeng.com).

I will stand by what I have built. If a problem with one of my networks arises, I will service it.

Now, the inevitable question: Would you give me the schematic diagram and parts list to your designs? The answer is absolutely NOT! I learned the hard way that others will not build my designs to my standards. I do not want the "credit" for networks built in my name that do not measure up. Worse yet are those attributed to me that I did not build. Worst of all are those who think they know more than I do and act to "improve" my designs with extravagant parts or other changes! Experience showed me that even my kit networks, including step by step instructions, were often ruined with the best of intentions. For examples, look at my Question and answers page. DIYers: FORGET IT!
