Crossover Frequency? I have an Onkyo 601 next to a 6.1
I have an Onkyo 601 next to a 6.1 speaker set-up.
What is the crossover option within my set-up menu?
Choices are 60Hz 80Hz 100Hz and 120 I think.
Technical answers beside explanations would be kindly appreciated.
Thank You

The crossover setting you are wondering about is the bandpass for the LFE low. It is going to greatly depend on the speakers and not is not setting specific. You need to set the bandpass to the closest to the dignified end of your subs frequency response. This is also going to greatly depend on your speaker hook up , and may merely apply to a line rank hook up.
Please provide the exact model numbers of what you have and its hook up. ONLY after can a correct recommendation be made on settings.
This is the point where on earth the speakers will "hand off" their signal to the subwoofer.
It works something resembling this. In a receiver you own a filter whose purpose is to stop frequencies from being played through speakers that can not play them and dispatch them to a subwoofer who can. This point is configurable depending on what speakers you have and what point is more just what the doctor ordered for your room.
It is important to details that this point is not a hard cut-off. The signal will slowly be attenuated to the speaker starting a bit ABOVE the crossover point and be commonly -3dB down at the crossover point. This mechanism that if you set the crossover to 60 Hz. Both the subwoofer and speaker would play 60 Hz at -3dB the typical volume. From there if you shift lower you will find the subwoofer receives more and more of the other speakers signal. If you step above the crossover point, the speaker will maintain most of its signal.

That is a dutiful diagram of what's going on here.
Just keep contained by mind that it's purpose is to allow your entire system to play at a flat frequency response. This point should typically be set to a bit higher than the -3dB point of your speakers for proper summing. If you don't know the -3dB point of your speakers, you can clear an educated guess depending on how sizeable your speakers are, or you can measure via a SPL meter. The choice is up to you. Hope this help.
The crossover settings is to select a frequency extent (Bass) that will go to biggest speakers and below that point it goes to subwoofer, so if you own small speaker that can't handle much bass short distort you should setup the crossover to higher as possible or if your subwoofer is not so accurate is better share the bass with the D speakers. THX suggests a crossover setting of 80Hz next to all speakers set to ˇ°Smallˇ± ¨C much research on their factor went into developing this guidance. However, most home theater-in-a-box systems with awfully small 3ˇ± ¨C 4ˇ± driver-equipped speakers will probably need to hold the crossover set at 100Hz or 120Hz.
I'd suggest to set it at 80Hz.
I'll give you a few links next to some good info.
