Same problem as most of posts (C6 cap blown clean off board).

JBL should be made to stand by their engineering & repair/replace product!

Strengths:
Good Thump for home theater

Weaknesses:
C6 (capacitor 6) factiryt defect (50v used instead of 100v as spec'd)

Price Paid:  $25.00 from saved from going to

Summary:
I saved this sub from going to the dumpster. My neighbor had purchased it. He blew it and didn't have any idea what to do with it. I (being a Technician) said I would take it off his hands and see if I could fix it if he didn't want it. JBL service people were very helpful. Fixed it with a kit I purchased from JBL and they provided me with the schematics. I feel that if they know what the fix is and it was a design flaw....why did I have to fix it? Why did I have to pay for the parts? They screwed up, they should fix it whether in or out of warranty. I haven't had a problem with the PSW-D110. Good bass. Could be cleaner but not bad for a lower end Sub woofer.

Strengths:
Good "thumper". Great price (ha ha). Volume knob on the front a plus.

Weaknesses:
C6?

Summary:
Just got done reading all the horrible reviews about this model. Guess I got lucky.. I've had my JBL for just about four years now, and I have been very pleased. I keep the volume up high (about 3/4) and have always experienced room-filling bass. I've taken this sub to hell and back, and it has always come back for more.
What is interesting though (and the reason I decided to write this review) is that I too woke up on night to some odd booming sounds. The sub was the cause, and I still can't figure it out. It wasn't a machine gun sound, but rather a boom every 5 seconds or so. I first unplugged the sub from the receiver, but the boom persisted. Next, I unplugged the sub from the surge protector, and plugged it in a few hours later. I haven't heard the sound since. The sub continues to work, so I haven't gone out shopping yet. Disappointing to hear insufficient caps were used.. but mine is still working -knock on wood-.
Overall, I feel I've gotten my money's worth out of this unit. Great sound, and not too expensive. Even if it blows tonight, I still have a few months warranty from Best Buy.

Strengths:
Great sound, and has been a reliable unit.

Weaknesses:
All the bad experience others have had.

Summary:
Liked the subwoofer sound. Rocked the walls in action sequences on a medium setting....but when it quit...it quit. This speaker is long out of warranty, but suspect the same capacitor problem seen by other reviewers. I saw one review which said the service bulletin and info on repair kit to fix the problem was on the JBl website, but couldnt' find it. If anyone knows where the information exists will appreciate posting the info.

Strengths:
Good sound when it works! Strong Rich bass.

Weaknesses:
LED light doesn't indicate correctly whether a signal is being received....and it died just like the other reviewers said.

First experience with a subwoofer although have heard others. Sound seems to compare well, but not working presently.

Summary:
I read all the reviews up to this point, and it is clear that there is an issue with the C6 capacitor in this model. I also read the service bulletin from JBL concerning this issue, and they did indeed use a 50V instead of the correct 100V cap. My C6 was blown clear off the amplifier board, but I could still read that it was a 50V capacitor. So, JBL suggests replacing this blown out C6 capacitor with a 10uF, 100V, NPE cap. They also suggest replacing the C24 cap with a 100nF, 50V cap, the R46 resistor with a 47ohm, 1/4 Watt resistor, and the R23 resistor with a 20kilo-ohm, 1/2 Watt resistor. The whole kit is labeled part number 30721, or the C6 Kit from JBL. Another option is to find the parts separately from an online distributor going by the given specs, or even Radio Shack. To buy from JBL is more costly, $16, but you ensure getting the exact parts and even instructions on how to repair the product. JBL was very helpful when I called in. Although the product was too far out of warranty to fix, they let me know the issue and told me how to fix it on my own to save the money from a costly professional service.

Strengths:
Decent bass.

Weaknesses:
Reliability.
