Verified Purchase(What's this?)
This review is from: Polk Audio PSW10 10-Inch Powered Subwoofer (Single, Black) (Electronics)
I'm using this with an Onkyo TR-606 alongside a Toshiba 62" DLP HDTV and a full set of Polk speakers, and the sound quality is remarkable.
The only caveat is that the subwoofer input has two connectors, but you really only need to connect one of them. The manual is far from clear about this, and plenty of people will probably spend extra on a Y cable, or worse yet, put in an adapter which will add both cost and loss of fidelity. But just connecting to the left input works fine. Subwoofers are mono anyway, and the double inputs are primarily there to make certain wiring configurations easier, not to add more sound fidelity.

Hi, what's the Auto Switch and the other switch for 180 for? Thanks.

The auto switch is for the subwoofer to turn on and off automatically. Say you turn the stereo off and after a short time the sub will power off as well. The 180 stands for In Phase/Out-of-Phase. When this is turn on, the sub will be out-of-phase with the rest of the speakers. Sometimes this is needed depending on where the sub is placed. You can read more about this if you google "phase switch subwoofer".

What am I missing here? Doesn't the Cable connect to the Line-in jacks on the Subwoofer, which are female? The above cable is 1 Male to 2 Female. The 2 female jacks on the Subwoofer won't connect to 2 female Cable ends.

No, they won't connect that way. My sub is hooked up to my receiver using a Y-adapter that has one male and 2 female inputs. The Y- adapter plugs into the receiver with the male input. Then the females are connected to your basic red and white RCA cables which connect it to the Line-in jacks on the sub. So basically, all you need is some RCA audio cables (with male-ends) to get your sub running.

Does this Sub has an inbuilt amplifier or do I have to buy and amplifier/Receiver to use this with speakers?

Smith Hayward says:
The powered subwoofer has an inbuilt amplifier which amplifies a pre-out sub channel from your receiver. You cannot connect speakers to the "speaker out" connectors and then connect this subwoofer to an iPod, laptop, etc. using the R/L RCA connectors and get full stereo sound. If that's what you're asking... If that's not what you're asking then I don't understand your question.

I did purchase this sub and figured that out.
I should have deleted my question.
Many thanks for answering anyway.

You can buy that one, but then you'll need to run two cables to the sub. Why not buy a 1 female to two male and run one cable?

I don't own these and haven't seen the manual but the O.P. may be confusing the left-only setup with a bridged car stereo amp. Unless a subwoofer only has a mono input or says left-channel alone will suffice for mono, you should combine both channels. A Y-adapter may not give true mono in some setups.
The reason subwoofers can get away with a single (mono) driver is that bass becomes non-directional below ~60Hz. Unless the bass is perfectly centered between both channels, a one-channel input will rob the bass of important tones. Bass drums might exist only on the right channel, or 1/3rd of the way across the stereo image, etc. That's why a system where the main speakers can handle most bass above 60 Hz will give the cleanest sound.

For the comments about the "Y" cable. For some reason, I needed the Y cable in order for the "Auto" mode to turn the sub on. When I connected my LFE to just one channel (regardless if my fronts were set to "LARGE" or "SMALL"), it hardly ever came on unless the audio track had a dedicated LFE signal (i.e. my DTS movies) but adding the Y cable it's now coming on and staying on (until the receiver is shutdown) as expected for TV, Movies and Music. My other sub doesn't have this issue and also had 2 inputs but I only used the "Left" (which was almost marked as mono). All I can do is think that when you split it, the circuitry to detect a signal with just one connected isn't strong enough unless you raise the volume enough. Not sure if it is the actual problem but worked for me and may help others who's auto mode isn't working (coming on).
