Yes, I agree with everything you said and not being an engineer I don't
understand fully some of the principles discussed, though Matt and others
have taken the time to explain some to me.
I guess much of this boils down to common sense. Though I don't understand
all the various reasons WHY this is the case, common sense would dictate
that a round speaker that matched the round voice coil would produce the
most linear pistonic movement as I have already mentioned. Though some of
my explanations may have been off the mark a bit, I attribute that to my
lack of education regarding accoustic and electrical engineering. I'm an MBA
for Pete's sake, I CAN probably tell you the best way to market a
speaker...
.
But I appreciate this thread and learning more about speaker design.

oval speakers. But look at MOST of the speakers out there that use
pistonic

the
voice coil, which is ALSO round.
Naw, they use round cones because thats what they can get from CHINA the
cheapest!
Durbin makes a good argument that there have been some manufacturers
that experimented with OVAL drivers for a reason, there are PROS and
CONS to ANY cone shape.
It isnt because the VC is round.
I would think the biggest advantage to a round cone is its uniform
strength. An oval cone would not have the same strength at all point
around its cone as the round cone would.
But a round cone would have some FIXED resonance points, where the oval
cone would have TWO resonant points (one for width A and one for width
B) and there for not a larger single resonant point as the round cone.
(in not talking about FS, Im talking about only the cone)..
Its kinda the same type of reasoning where they tell you NEVER build a
square box, a square box will have a single resonance, where a box with
three different side length have three different and much smaller
resonances.
I can get more into this if you like.
