[QUOTE="keep_hope_alive, post: 8334253, member: 576029"] asking questions is great and that's why forums are here. i only use test tones for setting gains. if i need to evaluate crossover points i use pink noise and an RTA. you can get RTA apps for your phone (Audio Tools for Apple or Audio Tool for Android). each tweeter has a recommended frequency range and the crossover slope determines what safe ranges are. steeper slopes let you play lower. the woofer is a major player in determining the best crossover point. it will roll-off due to being off-axis. if it rolls off above 3kHz then you'll need to push the crossover point on the tweeter lower to match. as you force a tweeter to play lower it will distort sooner. a shallow slope takes longer to attenuate. the slope is literal - 12dB down when you are an octave lower (octave is halving or doubling of frequency). check out these graphs [URL="http://www.rane.com/note160.html"]http://www.rane.com/note160.html[/URL] [URL="http://www.linkwitzlab.com/crossovers.htm"]Crossovers[/URL] [/QUOTE]
