Crossover confusion

[Methost]

Assuming my Marantz crosses over to the LFE at 80hz when my mains (Axiom MTi22) are set to small, should I set the crossover on my sub way up and let the receiver handle the crossover? Setting my xsubs crossover at 120hz seems to make it boomy. But if my receiver is set to 80hz, shouldn't the sub only be getting signals below that frequency?

Yes, that seems right. However, if there is a switch to disable the crossover, use that. By the way, what subwoofer are you using?

I would agree with jaxvon as this is the accepted ideal method, but in some cases you may need to utilize the Xover in the sub to cut excess bass being passed through(this may also be exaggerated due to placement issues)

My advice is to experiment, find the settings that sound the best to you and use it. After all you are the one listening to it.

I have a Cadence Xsub.

Oh I do, but my method is to first try to use recomended settings and configurations so that I have a base point to start with. After that I follow my ears.

Crossover isn't a brickwall filter but a smooth curve that's meant to blend with the speakers. So technically its getting everything above it, just at a reduced amount.

My 2 cents.......

Use the receiver crossover, and disable the crossover on the sub. The only reason I could see where using the sub crossover makes sense is if your receiver is incapable of doing the processing. As for which crossover setting is best?? Only you can decide what sounds best I set mine at the standard 80hz. I've done extensive experimenting, and that seems to be the sweet spot for my ears.

I dont think my sub has an option to disable. Would just setting it's crossover all the way up have the same effect?

Yes. This will insure that the receiver is doing the bass management and not the internal crossover in the sub.

If you want a flat frequency response, you should bypass the crossover in the subwoofer if possible, and if not, set it as high as possible. If your subwoofer is then too boomy, set the volume level of the subwoofer lower (do not change the crossover). If your receiver does not have the ability to automatically set levels appropriately, the best way to do this is to have a SPL meter and, using test tones, set the subwoofer level such that it is the same volume as the main speakers.

Once again I must thank everyone here for the help. As always, this forum has been a great resource for me.
