as for crossover settings, this is what i recommend.
find a cd with heavy bass, disconnect your sub, turn the radio to the highest listening volume, but not all the way up, your radio will clip the signal. one of my radio goes to 35, i do my settings at 30 and don't ever go past that.
ok, turn the HP crossover up and turn the radio on the highest intended volume. now start turning the crossover down until you here the speakers start to distort from the bass, turn it back up a hair.
ok now the sub,
start at 60hz and turn on some music with alot of low vocals, now start turning your crossover up until you here vocals, then go down some.
with all speakers going run some sweeps and make sure you have a good sweep and you can hear all freqencies.
this is how you tune a daily. equilizers are used to compensate for excessive peaks, which you will have.
sorry LS1 RULES but your correct in theory but wrong in the real world.
you may have your LP set a 60hz and HP set at 110 and have no dead spots. crossovers will "bleed" over past your settings, how much they bleed depends on the brand of crossover and type of crossover used. electronic crossovers provide the best results but still can't chop off a signal at a desired freq.
and as for gain settings there are ways to do it without an "O" scope. but the scope is the preferred method.
for instance termlab will show your sine wave and can be used much like an o scope.
the most popular method is using a multimeter.
if i remember right, you disconnect one speaker lead and put the meter inline with the pulled lead and the amp. using volts you turn the gain up while playing a test tone and wait for the voltage to stop going up. when you reach clipping the amp no longer puts any more voltage into the speaker. turn it down slightly.
final adjustments are always made by ear, these are ways to start, tuning is an art.
