AV Receiver Crossover Question

[mnsportsgeek]

I’ve had a pretty basic set of Klipsch satellite speakers with powered sub for 5+ years. I’ve got them paired with an Onkyo TX-NR676.

The manual for the Klipsch speakers says to run the LPF and crossover at 150hz or use 120Hz if 150 isnt available.
The receiver has a 150hz crossover available for the speakers, but only goes up to 120hz for the LPF.

The question I’m struggling with is should the LPF and crossover match to avoid losing frequencies? If I set the speakers at 150hz and the subwoofer at 120hz, will the frequencies between 150 and 120 be lost?

So I guess ultimately my question is should I set the crossover and LPF to 120hz, or should I set the LPF to 120hz and the crossover to 150hz? Or should I turn off the LPF on the receiver and set the LPF at the knob on the back of the subwoofer?

Thanks in advance for the help! I know I’m dealing with basic, entry level speakers here and either option will probably be fine. Just want to learn best practices for the future when I can upgrade equipment.

Setting the LPF to 120 should send all frequencies below 120 to the subwoofer.

Setting the crossover at 150 means the receiver should start rolling off frequencies below 150. Depending on the steepness of the cut-off, there could be a "hole" in the 120 to 150 range.

I suggest comparing 120/120 to 120/150 and select the version that sounds best to you.

Thanks for the feedback! Much appreciated.

that receiver has automatic EQ, just set the mic up and let the software (written with the help from people who have advanced degrees in this sort of thing) do it's magic.


I used to have a Denon receiver, and I'm pretty sure it would handle the LPF/x-over settings automatically, when you tuned it with the mic.
in case it doesn't, set the crossover to 150, and disable the LPF, before running the tuning.
