Up for sale is a pair of modified Klipsch Type AA crossovers. I've been building these since 2004. These will work in the Klipschorn, LaScala, or Belle Klipsch.

I normally use Jensen paper in oils, or Jupiters for these builds, but decided to build something a bit more affordable - something that bridges the gap between "relatively inexpensive" and "oh crap".

After trying some different builds in my LaScalas, I've decided to stay with an AA type build. However, I am making an important change. Since the great majority prefer a little bit of output shaved off of the midrange, I'm going to go ahead and incorporate that into the build. However, I think an additional 3dB is too much (6dB total). So, the midrange will be attenuated 4 - 4.5dB, which sounds "right". I personally prefer the stock setting, but I have a small room and listen at very low volumes.

Adding the additional attenuation also allows for a lower value primary capacitor (10uF instead of 12 -13uF), which means a higher quality capacitor can be used. There are more high quality 10uF caps then there are 12 or 13uF.

Capacitor choice is always a challenge for me, especially when trying to build at a lower price point. There really just isn't much of a difference between inexpensive metalized capacitors.

I've decided to use the Audyn Cap Plus, because it's double wrapped (like an Auricap), and non-inductive (like Mundorf). It also has a very high voltage rating (800Vdc), which means it's more linear in its performance. It's a very good part, and doesn't come attached with a voodoo audiophile price.

The price is $525.00 a pair, built on red oak, Universal Transformer autotransformers, Erse Super Q low pass coils, and the Audyn Plus capacitors. I will not be using the zener diodes, which I think are unnecessary.
