Klipsch SW-8 terminal Connection Questions

[PatrickCostigan]

    Hello. We recently moved into a house in which the previous owner had a built in entertainment center. He also left a 5.1 A/V surround sound receiver with some very nice front speakers, and 3 sets of Sonance in-ceiling speakers, which are in several rooms. Each of these speaker pairs have their own in-wall volume control, all commonly connected, with output from a Klipsch SW-8 subwoofer. My questions are about the cabling I need to establish between the Yamaha RX V-590 receiver and the sub. The SW-8 has two RCA type input terminals & two RCA type output line level terminals. It also has has two sets of left and right High Level (speaker level) terminals.  One is  marked “TO SPEAKERS” and the other is marked “FROM AMPLIFIER”. The previous owner’s cabling between the A/V receiver and the subwoofer consisted of two, 4 conductor speaker cables. One was marked “TO SUB” and the other was marked “FROM SUB”. The A/V receiver has a Low Pass Terminal for output to a monaural amplifier driving a subwoofer.. Only frequencies below 200 Hz from the a front and center channels are output

    I must admit that I have never had a subwoofer in any stereo system that I have owned. But I don’t want to have Sonance ceiling speakers that I don’t use. My questions are:

1 - should I connect the output from the receiver’s Low Pass Terminal to the subwoofer’s monaural Line Level input?

2 - should I then connect the 4 conductor cable marked “FROM SUB” to the subwoofer terminals marked “FROM AMPLIFIER”?

3 - should I then connect the 4 conductor cable marked “TO SUB” to the subwoofer terminals marked “TO SPEAKERS”, matching the polarity from question #2?

Will this allow me to correctly connect the A/V receiver to the subwoofer, in order to provide low level output to the ceiling speakers in my other rooms?

Thanks in advance for any & all responses.
