Connecting a PSW10

At the risk of covering ground already covered...

My receiver has 3 possible outputs for the sub:
- a single low pass sub out (RCA)
- two front line outs (RCA)
- standard front speaker connections

I guess I can use any of the above to connect to the sub:
- the single low pass out can go to the Left line in on the sub
- the front line outs can go to the L & R line ins on the sub
- speaker connections can go to the sub speaker inputs

Is there any real difference? It seems the middle choice (L&R line outs to L&R line ins) would be the simplest.

Thanks for the comments

    Welcome to the Forum Thomas......

    Try the different ones and see which you like best. I just picked up a couple splitters and am going to try another method to perfect what I have already. Right now I'm using speaker cables to the sub and I'm wanting to try RCA's for a change.

    Welcome to club polk. :)

    What front speakers are you running? What kind of reciever do you have? The reasons these questions are important....

    If your front speakers will reach down to 80hz (or lower) as a -3db point (will be in the specs for your speakers) just hook the sub out to your subwoofer and turn the filter on your sub all the way up (or plug it into an unfiltered input on your sub if there is one). In your reciever you will set the sub to on (or yes) and your the rest of your speakers to small (I am assuming).

    If your front speakers will not reach down to 80hz, hook up the sub one of the other two ways (either RCA or speaker level - with that sub I doubt there will be much of a difference) and set the level and crossover on the back of the sub to blend well with your speakers. (play music you are familiar with to set the sound (crossover and level) movies just will not cut it for this one.) In your reciever, set the sub to off (or no) and front speakers to large - (rear speakers will still be set to small).

    If your receiver (also called an AVR) has variable outputs for the bass (usually 40, 60, 80, 100, 150, 200 hz) just pick the lowest number that is above the -3db point of your front speakers and set it up like option 1.

    If this isn't clear or you have any other questions, just ask away...

    thanks for the quick replies and the welcome...

    My fronts are Polk AB755 in-wall speakers (32Hz-26kHz). Regardless of the specs, they really lack in the base department -- I think because of the large volume of air behind them (the inside of my wall!).

    My AVR is an "older" Yamaha (about 5 years old). The sub-out is set at 200hz.

    I suppose I can just play around with this and see what sounds best.

    (ps. what does the "Phase" switch do?)

    Thanks again !
