Had to do a little unexpected work on my SVS last night

I'm not sure if any SVS owners have had a problem like this, but here is what I experienced last night with my PC+:
I started watching a movie, probably the first in a week or two. The damn bass sounds a little funny. Its an older movie, so I thought the soundtrack just wasn't good. About 30 minutes into the movie, I couldn't stand it, I had to get up and investigate. I was hearing some crazy vibrations coming from the direction of the Sub. Put my ear close and it sounded like it was coming from inside the sub
So I pulled it out a little and sure enough, it is coming from the sub. I rap my knuckles on the side and there is a very aweful sounding ring that comes from inside. I paused the movie and turned off the sub.
Broke out the screwdriver and first I started with the tubes on top. I tightened them cuz I noticed they were a little loose. Didn't help the noise at all, so I pulled out the 10 or so screws that hold the amp in and pulled it off. I had to disconnect the wires from the woofer because there was absolutely no slack. Once the amp was out, I found about 3 or 4 screws that had come a little loose.
I tightend them all down and started to reassemble, but I can't manage to reach inside and put the wires back on the woofer terminals. Its too tight because the terminals were on the opposite side of the amp. I was thinking, what jackass put the woofer in this way? I gave up after a few minutes of fussing and decided to take the woofer out and re-orient it.
That was kinda a pain, the base has to come off, then the woofer is held by about 10 or 12 screws, but it was worth it because it was the first time I really got to look at the beauty that lies within the PC+ sub. Chrome plated magnet, aluminum woofer, just a marvel. Anyway, put the sub back with the terminals facing the amp and tried again. It still wasn't easy because of the way the amp frame juts into the cylinder, but I managed after awhile. If I did it again, I would have oriented it with the terminals about 90 degress from the amp instead of directly facing it. Oh well.
Anyway, got it all back and took the time to tighten every single screw that I could find. Fired it up, and nothing but clean bass again! Took more than an hour total. By this time it was late so of course, I ended up falling asleep before the end of the movie dammit!
So, if your SVS starts making funny noises, don't worry too much, spend about an hour to tighten everything back up and it will be fine. Of course, you better have square bit drivers, and multiple sizes of phillips head too. In all, I probably used about 6 different bits including a flat head to pry out the amp. Good luck.

I'm kicking myself because I didn't put loctite on the ones that came loose. I'm sure in a year or two, I'll probably have to do it again, but that will be the last time, cuz I will use loctite then!For rig details, see my profile. Nothing here anymore...

Haven't had any problem with mine. Maybe I'm not using it enough:D I will be tearing mine apart when the new woofer is shipped.
Glad to hear it was not to bad to fix.

After this thread, I checked mine in several spots.
The screws around the amp (on the cylinder and the actual plate) could be turned 1 or 2 times, sometimes more...
The screws holding the base on could be tightened 3-5 turns...
Various screws on the amp could be tightened.
Thank god i have over 300 bits to chose from because they used alot of different types.- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit. -

I found quite a few that were loose on the outside, but the REAL culprits for the vibrations were from the inside on the amp on one of the circuit boards.For rig details, see my profile. Nothing here anymore... -

As I was reading the thread as was thinking I wonder if he used any Loc-tite? Oh well, at least you know what it is the next time it happens.Carl
