The KSN-1005 with its long snout is the one I never really liked. It is more efficient, but sounds noticably different. There are some others that I don't like, such as the versions that aren't horn loaded and most of the generic knock-offs. But I like the Motorola KSN-1038 and I've stuck with them for the low cost two-ways for over twenty-five years. There's just a sound that I like and a simplicity of the design that appeals to me.

There is a slight rise in both the current Alpha 8 and the Alpha 10 in the upper vocal overtone region, around the 2kHz to 4kHz octave, just before upper cutoff. That's what the 0.5mH coil is for. I find the one π and two π speakers to be very pleasant, and I've always been proud of them. But if you want to build a more expensive speaker, you can always make different choices.

As for me, I think the one π's and two π's are perfect, just the way they are. I can't think of any better set of parts that gives so much satisfaction for fifty bucks.
