Axiom Home Page Forums General Discussion Stereo Crossover setting for a Sub

I think the Rel instructions are only thinking of stereo systems with full-range floorstanding speakers, not AV systems with smaller center and surround speakers.

It's possible that the crossover setting on the Rel subwoofer isn't actually the 3dB point but more like "the lowest frequency the mains can handle" then the actual -3dB point is somewhat higher than the number the dial is pointing to, eg. if you set to 25 Hz the -3dB point might actually be 40-50 Hz. Just a guess though.

Isn't REL's suggestion the way subwoofers used to be used way back before home theater? I am a big believer in higher crossovers, but I do see where they are coming from.

I bought an M&K subwoofer long before home theater was popular.I recall them saying to set the crossover to the - 3 db point of the mains. They also said if a person did not know what this spec was to set the sub to 85Hz.

The real beauty of our bass management systems that we put so much faith in, is the fact that we just KNOW that all the sonic information recorded on our CDs or DVDs or whatever, is going right to our subs along with the LFE stuff, no matter what.

That all that center channel data below 80hz or so is going right to our subs if 80hz is our crossover setting. That our surround sound data below 80 is doing the same all the time.

We just know that not one cycle of info is being lost.

We know, cuz it's set up that way! Right??




It's also a blessing that our subs all sound just as good as our mains.

I mean; we sure wouldn't want to be giving so much responsibility to an inferior sounding transducer.

Rick, I listen to several genres of Metal mostly, but other music as well sometimes (easy listening). Bass, especially tight, fast and accurate bass, is an important feature at my music as well.

With the type of music you listen to do you really get that much info from metal that goes to 20 to 25 Hz. It would seem that a higher setting would serve you well.
