That's it exactly, good job! It doesn't relate to your previous question, but I dearly love it as an illustration of the difference between front and rear duplexes. Indulge me. I'm old, not that bright, and easily amused. The front duplex thing, incidentally, doesn't care if the duplex is long, short, tuned, or not. The effect is the same. The rear duplex thing you asked about is, I think, pending more sensible explanation, the length/excursion/mass thing. Pending further enlightenment, and entertainment... Ron N
