    -Impressive home made equipment - I must say.

    yggdrasil! Im impressed

    Very nice home made milling machine for the routing process. I can see that you could make any sizes of horn mouth in this jig.

    Do you have any "blue prints" of it ? If yes, could you send me a PM ?

    Regards

    The project have been finished a couple of months now. Things really do take time.....

    Here's a couple of pictures a while back. The 2405's have gotten their own stands and both the stands and the mid-horns have the same finish as the main cabinets.

    I have attached the frequency response of the mid - hf section. It is an average of ~50 samples, no other smoothing.

    I designed the crossover with 24dB slopes on both the 2425 and 2405 while giving the 2235 12dB slopes.

    I added zobels on all drivers.

    The l-pads are built with resistors (other values than in the drawing), and are chosen by measuring and listening.

    Neat project!

    I'll keep watching as I too love horns for audio!

    Still very impressive... I have quite a bit of patience in the wood shop... not sure if I have that much.
