PSW 111 not working with Onkyo TX-NR708

Hi. I recently was gifted a TX-NR708 receiver (which I love), and then later got a PSW 111 subwoofer. I've tried hooking these two together with little to no success, as no sound comes out of the subwoofer (even when the receiver is in setup mode and is sending audio to the other speakers for a sound levels test).
I currently have the subwoofer hooked up with a regular red and white RCA cable, with the right audio jack in the proper port, and have set it to LFE and ON. I've left the Phase to 0 but I'm not entirely sure about any of this in terms of what I should mess with, so I figured I'd come to the experts.
I have a subwoofer specific cable, but that doesn't fit into the sub input in the back of the receiver (or maybe it just fits poorly, it feels loose). Any advice?

Hello,
Welcome to Polk's forum, I'm sorry there's a problem. Let's see if we can determine where the problem might be. To do this turn the volume down on the sub and remove the cables you have from the subwoofer. Then disconnect your DVD player (I'm assuming you have one of these) from your receiver and bring it to where the sub is. Then use a good quality cable connect the right and left audio outputs, of the DVD player, to the corresponding right and left inputs on the sub. Then start playing a CD and turn the volume up very slowly on the sub until you can hear sound.
Let us know what you find.
Regards, Ken -

I did as you asked (sorry for slow reply, took a while to get a DVD player that used RCA), and got sound. So it's not a dead subwoofer. It was boom-y sound, a lot of base, but that's normal, right?
At least I know it isn't busted. -
Hello,
Thanks for doing the test, now we need to figure out the receiver's part in this. The sub-out connection (a purple RCA connector), on the receiver, is located to the left of the antenna connections, if you're facing the back directly. This connection is the same RCA type connection that you used to connect the DVD player, but just one instead of two.
The other thing you'll have to do is go into the receiver's setup instructions and turn the "sub-out" function "on".
Regards, Ken -
I have turned on the subwoofer output before this, and I did make sure it was plugged into the right place. I know it works, because it outputs sound, but only when touching the tips of the connectors or hooked up to that DVD player.
Apart from that... -
Hello,
In that case it would be best to telephone Onkyo's CS guys, there might be a defective sub-out function on the receiver. An alternative way to connect the sub is to run a second set of right and left speaker wires from the receiver's front speaker connections to the corresponding right and left speaker level inputs on the sub.
Then set the receiver to front speakers "large" and sub-out "off". This method works as well as the sub-out connection.
Regards, Ken -
And that won't stop my speakers from sending sound? Because I have two polk R50s hooked up to the front section.
-
Hello,
The front speaker will function as they have always done,
Ken -
Okay. For clarification (So I don't destroy anything), do I run the wires into the area where the front speakers are already plugged in? That's not a bad thing?
-
Hello,
Correct, there would be two sets of wires running from the front speaker connections. One set going to the front speakers and the second set going to the sub. The sub contains it's own bass amplifier, it won't cause any problems with the front speakers, all of the receiver's power will still go to the front speakers.
Regards, Ken -
Okay, I matched the wires and plugged them in, onto the top set of inputs for speaker wire on the sub. I changed the settings in the receiver. What should I do now in terms of flicking switches on the back of the sub, and then how should I test if this works?
-
Set the sub's volume to around then 9:00 o'clock position and set the auto on/off to the "auto" position. Set the variable low pass filter to around 80Hz and simply play some music or watch a movie.

Thank you so much, Kenneth, I can feel vibrations through the speaker. Sadly I can't adjust it perfectly right now (I'd wake up the neighbors), but tonight I'll configure it to where I want it. Thank you for being such a huge help.
-
I'm glad the sub's working, usually a volume setting of 9:00 to 10:00 o'clock will give plenty of bass information and not sound overly boomy. If the sub is near a wall or corner you can reduce it even further.
Enjoy, Ken
