Post Subject: Flat cone geometry?Posted by haralanov on: 8/15/2010

Paul, the
problem could be unsolvable if this peak is due to cone geometry. Flat cones in
general behave very good up to a certain frequency, but they have strong standing wave
mode (its magnitude depends of the internal damping in the cone) above that
frequency which is dependent of the cone size and it’s thickness. If your Reps
driver uses the same paper as the original Lowthers – you are in trouble (I
wish I was kidding, but I’m not). It is very thin and weak and it can’t resist
the fast acceleration of the voice coil above 2-3kHz. The ribs of the cone
improve the situation, but not much. I took a photo of a friend’s lowther – is the
main cone the same like yours?
Best regards,
Haralanov
