What is the best Hz for a subwoofer?

[Tom Walkers 5]

Hi, there! What is the recommended crossover frequency for the subwoofer?

 

[DizRotus 9129]

Too many variables for a simple answer.

Hi Tom.....welcome to the forum.  I'm betting my gear is different from yours but my SVS PC-2000 Pro is set at 50.

Yeah, too many variables. You just gotta experiment with your particular combination of sub, speakers, room and 'your' ears.

Depends on the low frequency cutoff of your main speakers. Ideally, the subwoofer would take over seamlessly from the low end of your main speakers.

 

Start by setting the subwoofer high pass filter to the manufacturer's spec for the low frequency limit of your main speakers. Adjust up or down from there.

Whatever frequency makes the sound.......................hertz so good 😀

Well, The recommended crossover frequency is 80hz.

That would depend on the characteristics of the speakers that the subwoofer is working with.  Some speakers have useful output down to a relatively low point, so the accompanying subwoofer crossover point should be set fairly low, while if the speaker’s useful low limit is not that low, the sub rolloff should be set to suit that.

 

Since the frequency response of both speakers and subwoofers does not cut off sharply, you need to set the crossover point to allow a certain amount of overlap.  This will avoid having a dip at the crossover point, where both the speaker and sub will be down by 3 or 4 dB.

 

If you have a sound level meter (an SPL meter) and a test CD, you can check the combined output of your main speakers and your sub, and adjust the sub’s high frequency cutoff to give the smoothest bass response, with the minimum of dips and peaks.  You won’t get perfection, but when you’ve got it as good as you can, it’s time to put away the test equipment and just enjoy your music.

 

Welcome to the Forum and happy listening!

Thanks for your recommendations.

The question really cleared up.

But I should have been more precise with the questions.

I recently bought a ROLLS SX95 Stereo Subwoofer on Amazon, now I'm testing it.

my blend well below <60hz with La Scala's in my room.

60 Hz. is the best choice in my experience, but I prefer 40 if/when possible.

Start at 80 and tweak from there.

Starting at 80 is a great recommendation, thanks. It turns out there is an opportunity to find out the best option for your device.
