Default Q113 / Pandion

In looking for the next project I stumbled on to information about System Audio's design process of Pandion speakers. It seems that the designs were largely based on volunteer work and some or maybe all of the data was published on a blog.

I've seen that there were two versions: evolution and revolution. I understand that the evolution became Pandion 2 and revolution became Pandion 30. I don't know how close the final evolution/revolution information is to the Pandion 2/30.

I am having difficulty in finding the the designs of the final Q113 and/or Pandion.

Does anyone have diagrams/drawings/schematics/parts list for Q113?

Thanks!

Plans for the q113 can be found online but it takes some digging

I have crossover schematics and cabinet drawings for both pandion 2 and 5.

The only difference between them are cabinet size and different values on some components in the crossover.
The cost of building them are the same for both.
Funny how the price for the pandion 5 are double of the pandion 2.
They only use cheap components in the crossover, same for the pandion 30, the 50 I don't know.

But I see no reason to build them other than fun when you can buy them used for only a little more then DIY

System Audio is really hard to buy in Australia. There is 1 place that I know of that sells them. The price is high. They are clearing out stock so the prices are better but still high. After that I have no idea where to buy them as I have not seen them on second hand market.

I like how the System Audio speakers sound, the ones that I heard. I own Saxo 50 that I bought. They were the floor clearance stock and the price was really good.

My interest is because I like how they sound. More importantly I was hoping to use the design and change the crossover to active. So I wanted to see how good they can become with the change in crossovers.

As the project was an open collaboration I thought it would be ok to use it as a reference. It's a known reference so a good starting point.

As a note here are the current prices:

Pandion 5 $US 3,060.77 (SOLD OUT)
Pandion 30 $US 9,182.92 (on sale for $US 4,897.27)


Would Pandion DIY cost $US 1000? 1500?

Hello Gwurb,

Were you succesful in your search for Q113 drawings?
Is so, I'm interested. I spend already quite some time searching but I cannot find any practical information about the Q113.

Thanks in advance,

Daniiel
