High pass filter on psw125

Hello guys,

Just wondering if anybody knows the frequency at which the high pass filter on the psw125 is fixed?

Meaning at what frequency the subwoofer filters everything from, when using the high pass filter built into the subwoofer.

This question is because I am going to use a 2.1 system and would like to know what frequencies the bookshelf will be receiving.

Regards,

Eduardo

    If it's like the PSW110, the dial is a Low Pass dial and only affects the sub output frequency.

    Using a speaker level connection, the sub will output frequencies at and below the Low Pass dial setting and the speakers will always get full range output regardless of the low pass dial setting.

    Using a line level (LFE) connection, the Low Pass dial setting will combine with the receiver's crossover setting (if available) thus double-filtering the sound.

    Eduardo, although a very few subs do have a separate fixed(commonly at 100Hz)high-pass filter on their speaker level outputs, it doesn't appear that the PSW125 is one of them. If you have specific information to the contrary, you should contact Polk directly for details that don't appear in their materials.

    If not, and you have a filtered sub output from your receiver or processor, you should connect it to the unfiltered LFE input on the PSW125 and connect the speakers directly to the receiver/amplifier. If you don't have bass management available in your receiver or processor, the low-pass filter control on the sub will roll it off above(roughly)the selected frequency, but this isn't a crossover(subs don't have internal crossovers)and has no effect on the speakers, which would have to run full-range.

    thank you fir th info,

    i guess it does not have a fixed high pass filter, which is what i need to hook up a sub to my audioengine p4 speakers, the amp is a small desktop amp by them as well.

    thank you all,
