New To Home Theater: Need Help Calibrating/Setting Crossover Frequency

Ybaiani, something here is not right. There's no way these speakers go down that low. They are great speakers but not that great.

Do me a favor, google "50 hrz note" and download it. Basically it is a 10 second 50 hrz dash.

Let me know if it comes out of any speakers, and if yes - from which.

If 40 is your cutoff point (given that you have all speakers cut off) then the 50 hrz note is supposed to come out of the speakers, but I kind of doubt they will dig that low, especially under normal listening levels.

If you do hear the note - you are golden.

Doing it right now. Trying to find the frequency but am not having any luck. Will post updates here in a sec.

Okay, here's what I got so far.

These were the files I tested.

All of these came out of the subwoofer.
30hz
40hz
50hz
60hz

I find that very strange as the EQ is what gave these crossover frequencies. What do you think? Are there better files to test with as these files were only coming out of the subwoofer??

... Initially, the audio sounded good but wasn't great. The subwoofer was sounding a little funky and was actually hurting my ears. I went ahead and did an EQ and got some weird settings.

1st EQ:
Fronts: 100hz
Center: 40hz
Rears: 80hz

The sub sounded really boomy with these settings and I'm not too sure why. ...

That's exactly what I would have expected, and why I suggested trying the lower settings earlier. Those BIC/Acoustech subwoofers are great, affordable Home Theater subwoofers, but they're not very musical in my experience, and they are indeed boomy when the crossover is too high. This is probably a matter for personal preference, as I said earlier, but I hate boomy or sloppy bass ... especially if it's not associated with an explosion or something similar!

You may have a challenge taming that effect for music, though, if it bothers you like it did me. Some receivers allow you to memorize different settings that can be accessed at the touch of a button on the remote, making it extremely easy to optimize settings for Home Theater and music listening separately. If yours has such a feature (or has a dedicated subwoofer volume button), it might be worth investigating those options.

so the notes over 60 came from the speakers?

Perhaps set all speakers to 80 then.

You must make sure that the speakers can play the bottom end of the signal that you are routing to them. For example, if 50 hrz is sent to them but they cannot play it, then your crossover should be no lower than 60
