In the frequency response curves, the distortion looks a little bit high.
Or am I misinterpreting the curves?

Still have to do new membranes to the new motor as it is somewhat wider and double the height of the old one.
I plan to have two membranes in series for each motor.

Wow
Those are big
Even the 15" speakers looks small.
It is a good idea to make 2 diaphragms .
How many pleats? Width,depth and hight?
Do you need 7my alu/paper? I got some.I have 10my alu/paper too.

The waveguides are "tuned" to 500 Hz.

Alu/space ratio is 5/3 mm and fold ratio 6,5/1,5 mm, pattern is attached.

Since the trip to Copenhagen this summer I have all the 10 um alu/paper I need, thank you for the tip on where to find it Click the image to open in full size..

It is the AE TD15H with Apollo upgrade.
I'm currently XO at 500 Hz @ 24 dB/octave.
