tweeter capacitor

Won't even a good 2way system suffice? I mean, as long as the tweeter can reproduce freq's above 10kH, right?

Time delay will probably eliminate the need for them also, correct?

It's just that i've never even heard of 'ambient tweeter' systems. I figure it would be in the comprehensive front stage sticky if it was necessary.

Lastly, now this is all theory again:)  The engineer at Polk Audio told me to use a 6db crossover to get a smoother roll off curve.  Where as there's other companies that offer 24db ambient tweeter sets.  Wow!  What a difference.  Maybe it's because of the SR tweeters itself.  I know it can go down to 3k.  Maybe that's why they told me to run a 6db for the ambient set.  Who knows?  Anyhow, here's the picture. 

He probably told you to build a 2nd order crossover because it's so far superior to using 1st order, and less expensive than building 4th order.  HERE is an assortment of calculators.

Your tweeters should likely perform to another octave below 3K.

Is that a center channel in the middle of the dash?  Get a grill on that thing!

I hate the sound of so-called "ambient" tweeters.  You will most certainly want to include a pad on those things unless you like harsh sibilance in your face.

I've been thinking about them. I figure they would help in a low powered system or even to add them to factory systems where a single fullrange driver is used.

This, BTW, is what you call a theory.

Yes that is a center channel.  It's 5.1 Dolby Digital using the alpine processors.  I didn't want to use the grill because I highly doubt anybody will damage them up high like that.  I guess and acquired look!
