how to tune a crossover

can sumone quickly explain to me how to set up a 3-way crossover after intallation

should be easy to set, does the amp have a built in crossover too? (this does matter)
oh and u need to know the frequency response for your speakers.

[boom master cumup]

no the amps dont have built in crossovers

[Zilla]

ok well hence the need for the external one, a crossover is basically for setting specific frequencies for your speakers to play at, as they are commonly designed to play a specific bandwidth of frequencies, all u need to know is what ranges the speakers require and the capable frequency range of your amps and you can now begin to tune the crossover to suit those needs, remember that amps generally have an effective frequency range that they can function at, so u have to be careful not to set the xover out of that range.
If youre having trouble you can provide model info of your equipment and i can research the specs and help you set the most effective range for your system. hope this helps

Setting it up by ear to achieve good results will likely be difficult.

Some starting points to consider:

1. Subwoofers:
Set the LP filter on the x-over to 80 Hz, 12dB /octave. Adjust to taste. If x-over frequency is too low, the bass will sound rumbly and anemic, with no "punch". Set it too high and the bass may likely sound too boomy.

2. Main bass/midrange drivers:
These speakers are going to handle most of the range, so you really want to get the settings right here.
Set the HP filter on the x-over to 80 Hz, 12dB/octave. If drivers are smaller than 6.5", select a higher frequency. If you tend to play your music loud, select a higher frequency. The best point is where you have a good match between up-front bass and power-handling at higher levels.

Set the LP filter to 3kHz, 12dB/octave to start. Move up and down slowly, while listening to music. If the music starts to sound a bit "shouty", back off the LP filter a bit. Also try shifting the slope, if your x-over allows it. You may be able to get away with 6dB/octave with decent midbass drivers with poly or paper cones. If the cones are made of more exotic material, like aluminium or kevlar, you'll need to use steeper slopes, if your x-over offers that feature. This particular setting is going to make a significant impact (our ears are more sensitive around 3kHz), so plan to spend a lot of time getting this particular setting right.

3. Tweeters:
The HP filter setting for tweeters is VERY dependent on the size and capabilities of the tweeter being used. For example, for a 1" tweeter, I would not go lower than 3kHz, 12dB/octave (you can try a bit lower, say 2kHz, if your x-over allows steeper slopes). For 3/4" speakers, start at 5~6kHz 12dB/octave. Do NOT use slopes shallower than 12dB/octave. Start at about 1.2 times the HP filter setting you used for the bass/midrange drivers, but not less than 3kHz. If mounting the tweeters in the sail panels or A pillers, set the output level of the xover at least 3dB below the setting for the bass/midrange drivers.

Then tune to taste
