Summary: hmmm...
Review: This sub worked phenomenally for a few months... but I noticed a couple months ago that the mighty bass has been brought down to nothing more than a whisper- it powers on and detects the input (which is apparently a step better than everyone else who's bought it), but the sub barely fires- i have to actually TOUCH the driver to make sure its working. irritating.

Summary: Sound greats if it works
Review: This unit sounds great for a reasonable price. Too bad it does not last due to the fault amp. I bought both PB10 & 12 and they all died on me in less than a year. What a waste of money!STAY AWAY FROM THIS BEAST OR PURCHASE SOME SORT OF REPLACEMENT WARRANTY.

Summary: Should be recalled
Review: We purchased JBL PB12 subwoofer June 2001 for $390. In July 2002 (barely after warranty period expired) there was a pop and then unit failed to get power. The unit wasn't even being used at the time and had surge protections in place. "Dead part - Amp module" replacement cost $165 and took four months to complete. Another pop and failure occurred this week November 2003, with less than one year of use after repair. We do not "crank up" the volume, nor have we ever pushed the limits of the unit. From reading multiple other reviews online, it is obvious that a significant portion of the product units are defective because they all have the same repetitive problem. Will attempt to resolve issue with manufacturer this coming week, but reading online documentation of people's past experience with lack of appropriate response from JBL is discouraging.

Summary: JBL needs new power amp source!
Review: Well, after reading the reviews and 4 out of 10 had failed amps, I no longer feel so all alone. I used to use a lot of JBL equipment with my sound company...that was in the 70's. I always have been a fan. I got this PB12 as a replacement for the PSW-D112 that I purchased in Feb 2001. It's amp blew out. Now after two years of limited use, this one has done the same. I guess it's time for a change of mind set. I give it 4 stars when it works...too heavy to be returning all the time.

Summary: JBL PB12 Amplifier flaw
Review: When I purchased the PB12 in October, I had to wait another month for all the other components for my home theater system. Once all was connected the PB12 was superb. It did everything I wanted and I didn't even have to crank it up. Movies sound better than music for whatever reason but I am (was) completely satisfied, until last week. On Wednesday 2/13/02, I was in another part of the house and heard a loud buzz. When I walked into the living room, I noticed the red led's on the PB12 were not lit. The system wasn't even running and the amp took out the fuse. I haven't had any luck yet to resolve this problem but have read several other complaints about the same thing. Good luck to all who have this great sounding sub and please wish me some. It sounds like I'm going to need it.
