PSW111 Going Bad? Anyone Else Have These Symptoms?

rdbussman

I bought a brand new PSW111 a few months back and once I got it in the right place in the room it sounded GREAT! The bass was full and present and it blended quite well with my JBL bookshelves (Studio L Series-L830s).

Recently while listening to music, I noticed the bass would randomly fade out and then fade back in. It doesn't seem to happen in regular intervals or with any consistency. Today, though, I find that the sound from the sub is pretty much not all there. It's as if there are patches of the bandwidth not playing. I played some tracks I know really well and the bass just don't sound exactly as it has before and I have not messed with any of the settings.

Currently I have the Low-Pass on the sub set to LFE and have it connected to the LFE/Sub-Out line on my receiver (Harman Kardon AVR-1600).

Anyone else going/have gone through this?

Thanks!

Hello RDB and welcome to the CP forum. You indicate that the bass output, of the sub, seemed to be randomly dropping in volume then coming back to full strength, correct? Now, it sounds as though there isn't any bass output at all, correct? If so, maybe the first thing to do is try this test:
1). remove the connections between the sub and your receiver at the back of the sub.
2). bring any high level source device (CD/DVD player or media server) over to where the sub is and using good quality cables connect the device's right or left audio output to either the right or left (or both) inputs on the sub. At this point don't use the sub-cable you've been using for this test.
Start playing the source (if you're using a DVD player start playing a CD as opposed to a DVD) and turn the volume, of the sub, to around 9:00 o'clock on the sub's volume. Notice how it sounds, see if there are any changes in the overall volume?

I plugged in my CD player and the sub responded. I got to 9 o'clock on the volume knob and it was pretty loud.

Good, let the complete CD play and see if the sub seems to play without any changes. If it does, then turn the sub's volume down and remove the connecting cable between the CD player and the sub. Get the original cable that you were using and make the connection between the CD player and the sub. Now begin playing the same CD and see if there are any volume changes. If not then the problem could be related to the receiver's sub-out connection.
