I don't know much about mounting but I always thought that in a 3-way you should mount all three components on the same axis. I'll choose the door pad.

Animal instincts, actually. Anyway, a good videotape should sort you out.

Midrange and tweet in one plane and the midbass in another is just fine. Dont try out any of the mounting sequences from the videotape with the speakers however.

for drivers to have a 6db XO they should not only be close together but also be capable of handling a lot of power (esp the tweeters) and have farily smooth roll offs.

series XOs (read Andy Graddon's paper on this) can be 2nd order as well and with careful selection of XO freq, drivers, etc.. one can make do with a quasi 2nd order slope approximating about 9db/oct. remember these are only electrical slopes. combined with the roll off of the drivers concerned the system slopes will be steeper (18-24db/oct).

if you study a series XO you will realise that since each driver is part of the other driver's XO the transition is natural.

Disclaimer: I have not yet used a series XO in a car. To attempt that one must have a full understanding of the individual driver's capabilites, frequency response curves, and T/S parameters.

Thanks for the info navin..
I'd really like to come for practicals and some theory! When do your classes start?
Do you give personal attention to each student?

Seriously! I'd love to learn..

Feeling frisky, eh, B&T?

Actually even I was wondering how MF is going to manage getting all the 3 on the same axis, and he choosing the door pad at the same time! The videotapes (videotapes, b&t bhai? Kya yaar, this is the age of VCD / DVD / downloads) are going to queer the pitch even more, really.
