Mine makes the electronic farting noise at least once during every movie I watch and after it's turned off.

It is annoying and embarassing while having any friends over.

I can't believe anyone would rate this speaker higher than one because most of the time it works.

This isn't rocket science. A speaker should not ruin any movies by making loud random noises.

Avoid it like the plague.

I too was interested in a cheap sub, and this seemed to fit the bill. I read about the farting noise when it went into sleep mode, and figured I could live with it. Well, maybe, but that's not the only issue I had.

The amp has two switch positions: "off" and "auto". It does not have an "always on" position, and this is a critical failure. At certain volumes, the auto-sensing "feature" will put the sub into power-save mode mid-song, overlaying the fart noise on top of the music. At this point, there's no bass, until the volume gets turned up, it senses the signal again, and it kicks back on.

In songs with quiet periods, or movies where explosions alternate with dialog, the sub turned itself on and off way too often - it was completely intolerable. I could hear a bass line, then it would be gone, replaced with the fart noise.

If you're cranking repetative industrial or techno, you won't have this problem, but users with other applications in mind should pony up an extra $23 for a better sub.

I wanted this sub for the bedroom. I have a romping 12" Infinity for the living room and I am happy with it. I just needed a little something for when I'm laying in bed watching movies in the bedroom. This sub does the job. I use it primarily for movie watching. I cranked some little jon the other day and I heard it bottom out a few times but it's a jenson, and it's less than $100. It's better than most subs you get in those all-in-one theatre packages. Go for it if your use is light. Don't buy this for the center piece of your primary sounds system. Always spend the most money on your center channel and your sub; You'll never regret; if You don't you'll end up upgrading soon and spending more money.

This sub does what I want it to do. It does fart. I love it. My girlfriend hates it and wants me to return it to Amazon but I won't. That's the only negative about this product, and I don't feel negative about it... It makes me laugh!!! The farts are few and far between, and mine only makes that sound when the stereo and TV are turned off and the lights are out and I'm about to fall asleep... Then it rips one, hilarious.

Amazon returns policy is Awesome. I purchased that mini-Koss DVD player and had to return it, Amazon made that entire process seemless. Amazon gets an A+++.

Had this for three months before it developed the dreaded "Jensen twelve-inch flattulence." Great deep bass until sleep mode and then "brrrAAAAAAPPPPPP!" and no signal. Turning it off and waiting a few minutes helps but then it starts farting again! While highly entertaining during romantic movies, it gets downright irritating when you're watching Star Wars and Darth Vader starts passing gas.

The only reason I'm giving this sub a high mark is because he plate amp at 2 ohms is incredible. The amp "farts" because of the capacitors in it get charged from the current produced from the sub moving because of sounds around it. Get a high Q sub that's 2 ohms and sounds good in a 2.5 cubic foot space and you've got incredible sounding sub. I've got an old Audiobahn AW1200 in mine right now and I'm having a hard time wanting to remove it.

Plate amp gets hot but pounds music long time...
