View Full Version : Coax and Crossovers

OK, I just picked up a pair of Alpine Type S coax speakers for 25 bucks at my local tweeter store to tide me over until I get enough cash to get a nice pair of Rainbows. I have a pair of tweeters from my CDT components that I blew that I would prefer to use over the little piece of **** tweeter in the center of the coax. I also have the passive crossovers that came with the CDT's.

Now, what I want to do is run my bandpass to the coax speakers and my highpass on to my CDT tweets from the CDT crossover. On the speaker there is a capacitor run in series to the driver, and I assume some sort of capacitor in the space below the coax tiny tweet. So can I simply snip off the capacitor on the coax and run the bandpass to it? I figure since the tweeter is so small on the coax it can't go very low, and therefore it should be almost completely outside of the frequency range of the bandpass CDT xover. Then I would run the CDT highpass to my CDT tweeter, probably attenuating it at +3 db since it is meant to be fed more power than the alpine woofer is.

Is this a good plan, or completely wrong?

Usually there's just a single capacitor in series with the tweeter, to block the bass from it. Usually the midrange has no such filter, and is run full range.

Since you're just doing this more as an experiment than anything else, with spare parts and cheap speakers, I see no reason not to give it a try.
