ok, right now I have Seas L18RNX in my doors getting about 100watts from an Alpine MRV-F540. Then I have an Arc4050XXK powering my Arc ACS230 mids and Max Fi tweets. I have the mids crossed at 2.5khz @ 12db, and the tweets are crossed at 3.2khz @ 12db. I know the tweet can go lower, but i like to play as many freqs as possible from the mids, so what should i cross them over at? The mids are made by Rainbow, i believe they are from the contour line of woofers, 5.25". The thing i dont know is if the freqs above 3.2khz would be better left to the tweet or mid. I tried playing with it but i cant tell, and i dont have a freq response graph of the mid so i dont know if there is any rolloff or dips/peaks i should be worrying about. I've tried doing it by ear but wanted to hear some other people's experience with MaxFi tweets or Rainbow Contour mids. Thanks.
