How to set Crossover frequency for Subwoofer

Theoretically:
The specs says that the speaker system frequency response is: 30 Hz to 25 KHz.
So, 30 Hz is my crossover frequency ?

Practically:
Is there a way to pass 30 Hz frequency signal to the Front L/R & Center Speaker and listen, they are responding to 30 HZ signal or not ? When speaker start responding that frequency will be exact crossover for the Sub.

Is this the procedure?

Thanks.

the lowest value of frequsncy does not mean you set your HPF from there. Usually speaker drivers are provided with a value called f/s and you should ideally cross from twice that frequency....
in your case I would advice looking at a frequency between 60 and 100.
try different frequencies and locations for the sub also

Which speakers do you have? When speakers set to Large, they get full range.

Even if you can set your speakers at 30hz, its of no use. Practically most drivers cannot go that low. Moreover, it puts a lot of strain on the receiver's amplifier to send those low frequencies to a speaker. You are better off doing bass management and allowing the Sub to handle the low frequencies. Cross your speakers at 80-90hz and let your sub handle everything below that.

I guess such topics are already covered in great detail on this forum, please search for them to avoid redundancy.

Set the Crossover frequency control to match the -6dB
low frequency cut-off frequency of the
speakers. Note: Both -3dB and -6dB figures can be
found in the specification of speaker.
If the satellite speaker manufacturer quotes
only a -3dB frequency, the optimum setting for the
Crossover frequency control should be between 0.6 and
0.9 times that figure.
Ex., for my B&W DM603 S2 are :
37Hz at - 6dB
48Hz at - 3dB
But generally you can set f = 60 80 Hz...

Its always advisable to let your sub do the heavy lifting in the low frequency end. Even if your front speakers are rated to go very low, it is mostly marketing bluff. So it is safe to set the cross-over around 100Hz.(THX recommends crossover at 80Hz).

Your speakers will thank you
