[QUOTE="mat3833, post: 8791921, member: 587645"] Thats not the real issue. Passive crossovers are a set crossover point and use 12db slopes. Nothing specifically bad about 12db slopes except in this case you are sending alot of extra power below the point you want the speaker to play. A huge limiter on how loud a speaker will play is low its playing. High passing your 6.5's at 80hz vs 100hz is a big difference in clarity and volume. Same goes for tweeters. If your passive set crosses them down around 2.4khz(pretty standard), raising that crossover point to 3k will let the tweeter take a fair bit more power and play alot louder. I don't know the formula, but for every octave you drop you require some measurement more power to reproduce the same volume level. By raising the crossover point, you are increasing the amount of mechanical power handling of the driver and also reducing the "distortion" present in the playback. Raising mb y midrange crossover from 250 to 500hz was a HUGE boost to my overall volume level and clarity. Matt [/QUOTE]
