Speaker settings for a BI-AMP setup?

[Nejc]

Hi,

I have my two main, large, self-standing, left and right Klipch Reference speakers bi-wired to a receiver (Sony STR-DN1080). They were connected that way by a friend who knows more about audio than I do; I am still a beginner (and because we had extra cable and speaker ports on the back of the receiver).

I already have the extra ports set to Bi-AMP in my receiver settings, but my question is this: should I still set ALL the speakers to small and use the recommended 80 hZ crossover for all the speakers (or maybe 60 hZ for the mains), or should I set the two front left and right speakers to large, and the rest to small with an 80 hZ crossover?

Either way, where should I have the low-pass filter knob set on the back of my subwoofer so it doesn’t interfere with my receiver crossover settings? The subwoofer’s low-pass setting goes up to 120 hZ, and on the right is LFE (see attached image)

In addition, the receiver also has a subwoofer low-pass filter ON-OFF setting. Which one should it be?


Thank you for your help!

There’s no good reason not to set all the speakers for 80 Hz. Set the crossover on the sub all the way up to the LFE setting. If the sub overloads during demanding passages, then turn on the high pass filter.

"If the sub overloads during demanding passages, then turn on the high pass filter."

You mean low pass filter? That's the only setting on my reciever.

When your sub is set to lfe on the lpf you can set the low pass in the avr. If your sub has a built hpf, it's internal. As for the biamping part, your not gonna gain anything except using extra wire, it's 99.9% marketing hype with passive crossover and with an avr.

Got it!

I've set my main left and right speakers to small, with an 80hZ crossover and set my sub low-pass setting to LFE on the back pannel of the sub.
As for the receiver setting, should I turn the subwoofer low-pass filter ON or OFF?

The lpf for lfe should be on and set for 120(unless you have special considerations). That controls where the upper range of the .1 channel is cut off. Lfe, or .1 channel is 3hz-120hz, and is completely independent of any XO settings. Therefore it's best to leave it alone. Unless, for example you have localization of lfe effects in movies(there's no .1 in music).

Cool, thanks for the detailed answer.
