[QUOTE="keep_hope_alive, post: 8214834, member: 576029"] above 3kHz the wavelengths are shorter than the distance between our ears - so we cannot resolve differences in phase. that is why tweeters don't need T/A in a 3-way system. 3-way systems use much higher crossover points (usually 4kHz or 5kHz and 24dB/oct). with 2-way systems, you usually have to use lower crossover points because the woofer starts beaming below 3kHz. you also need to factor in the slope of the crossover - if you run a 4kHz crossover that is only 12dB/oct then you still have appreciable output below 3kHz and thus T/A may be desired. it's system dependent - but in general, you can get by with level adjustment only in a 3-way system - either with balance or amp gain or crossover pads.
