Hello, I have a Bose Lifestyle 12 looks like there is something wrong with the subwoofer. I suspect it is the fuse. Since I have a limited budget to send to Bose repair Centers and the system is too old for $500.00 fuse. Can you please help me how to open the subwoofer. Thank you very much. |

A $500 fuse? Who told it would cost that much?

J. Vigne,
I believe what joas is saying is that the shipping of the subwolfer, labor replacing the subwoofer is going to be expensive or that a new subwooler will cost him around $500.00. Bose service can fix it but it will be $120.00 + shipping to get it fixed. I have the same problem with my Bose Accoustimass 15 subwoofer, it will not power up, I believe it to be the fuse. I too can't get the darn cover off, does anyone know how it done? |

I believe what you are seeing is called planned obsolescence. Bose glues the box together when it is assembled at the factory. If it comes in damaged under warranty, their cost is minimal to replace the unit. If it comes in out of warranty, their profit to simply replace the unit is still considerable. The owner can't prove it is just a fuse, so a non-repairable system is a fair diagnosis. That will be $350, please. Since the Bose systems can only effectively operate with their own subwoofer, the owner is in a positioned most commonly referred to as "screwed" to the wall.
But those satellite speakers are nice and tiny. Small wonder Bose is the most well known speaker company in America. Even smaller wonder Amar Bose is a very rich man.

Interesting thread. I have the exact same problem. Subwoofer stopped working yesterday. No Power. Accoustimass 15 that is 5yrs old. I am technical by profession and cannot for the life of me figure out how to get inside it... there is some kind of metal swivel on one end that swings out but doesn't seem to unlock anything. Would love to get hold of a some schematic.... |

If you haven't been able to get the back cover off of the Bose Acoustimass speaker yet:
Locate the plastic swivel tab with notches in the center of the top between the plastic grill and main case.
Rotate the notches with something small and thin, like a key, until a plastic tab is sticking straight out.
Hit the top of the plastic grill with shoe or rubber mallet toward the bottom of the case (where the cables plug in) to slide the cover over the internal grooves.
The case will fall off with no damage. |

One additional thing, remember to pull the treble and bass knobs off before removing the plastic side grill. They just pull straight out. |

When removing the side vented panel, remember to pull the treble and bass knobs off before hitting the grill. They just pull straight out.
Also the panel below the vented side is not glued on to the cabinet but uses a rubber gasget and therefore the electronics and speakers can be accessed without damaging anything simply by removing the screws . |

I got the back off; previous posts are correct. There is a latch on toward the rear in the seam between the plastic and the larger wooden box. Turn the latch until it sticks out. Make sure the side nobs are pulled off first then....
pull very hard on the black pastic away from the plugs and it will come off.
UNFORTUNATELY, I found the fuse right off, I tested it, and it was fine. I took both layers of circuit boards off and that was the only fuse and nothing else appeard wrong with the subwoofer. Alas, I will be hopefully making arrangements with Bose tomorrow for a repair or upgrade if they do such a thing. I have no idea why the power doesn't go through.
Good luck to all. |

The same thing was happening to my Bose Lifestyle... I took it to a local electrician, who couldn't fix it because Bose doesn't give out their repair manual or parts, BUT he told me it had something to do with the unit getting too hot?? Not sure, but I too am shipping my bose off to be fixed. I was quoted $190 for the repair- can only imagine what its going ot cost to ship it!! |

I have a Bose Lifestyle 20. As I live in an extemerly dusty environment I would like to open up the case and blow out all the dust. Does any one know how to open the case please. Also I have to go extremely close to the unit with the remote before I can alter or awitch the sound. The remote has new batteries. Would appreciate any ideas as to why the remote will no longer work from a distance. |

I have a Bose Lifestyle 20 which has eaten a CD. I have tried to get in to the unit to free the darn thing but again I can't figure out the magic code to crack the darn thing. Oh Bose will fix/replace it for $200. But I would like to forgo that if possible. Anyone have any ideas? Lots of little slots in the base but nothing seems to free any part of the case.
yes I tried the manual release on bottom. it releaases the cassette but the disk must be half way into the elevator. |

Regarding the subwoofer on the Bose Acoustimass system: Mine suddenly died as well and I at first suspected the fuse as well but it was fine, however tracing the voltage from the plug it stopped at two Surface Mounted Resistors on the opposite side of the board from the fuse(very tiny but marked "200" on each of them) they are in parallell and had both blown. They are 20 Ohm resistors (200 = 20 + number of zeros, thus 20 ohms) so I replaced them with some 20 Ohm 1/2watt resistors from radio shack and the system now works again. I of course had to tack them onto the board since they are not the surface mounted type, but no one will ever see them anyway... |

I have a Bose AM7 that worked well with an Onkyo Rec TX-525 that fried with a surge. Replaced it with the SR-702. The subwoofer seems to work softly (satellite speakers work normally) but the sound from the sub is no where comparable to the 525. Aditionally during the setup of the SR-702 does not recognize the Sub. I have played with all the crossover settings and eq yet no different.
Since the Sub does not seem to operate normally but only with very minimal sounds, I am thinking of adding a powered Sub.
Anyone see a conflict here? Have to use the Bose sub as it drives the satellites or is teh Bose sub Dead?
Thansk.

I have the Bose Acoustimass 15 system (6 years old) and am experiencing frequent woofer failure. Not sure what the deal is here, and none of the above situations sound similar to mine.
Yesterday I couldn't get the woofer to fire up at all. Flipping the on/off switch usually generates an audible sound from the power supply ("thump"), but it didn't do a thing. I tried turning it off and on several times with no success.
Today, after reading this topic, I was fully prepared to rip open the damn thing to see if I could find a problem. However before doing so I fired it up and sure enough it worked just fine. I didn't move it at all.
Yesterday it didn't work. Today it did.
What could be the cause of this? It's extremely irritating, especially when the family sits down to watch a good DVD and there's no bass.
Finally, if I can't find a solution to this problem, I'm going to swap it out with another 10" home subwoofer I have. So my 2nd question is, do the Bose satellite speakers work fine without being hooked up to the Acoustimass box?
Thanks for any advice...

Chris,
REJOICE, REJOICE, REJOICE...because Fortune has smiled upon you!
You now have the absolutely priceless opportunity to upgrade to a million times better HT system for the same or much less money than what you paid.
Those Bose sats can only run with through the Acoustimass box. Why? Because a REAL receiver, putting out REAL power, would fry those puny little 2.5" paper cones all to hell.
Likewise, a REAL subwoofer, not that joke of a "bass module" would also blow your Bose out into the next galaxy.
I can't answer your question as to why your woofer is doing that, but I can say with 110% absolute certainty that you will NEVER EVER regret the day you go and buy yourself a real HT system.
Here's the scoop on Bose in general, and on the Acoustimass system in particular:

The reason why I bought the AM system for my living room is because of space. I have the four Bose sats ceiling-mounted and the AM box is about half the size of my Velodyne 10" sub I purchased for my makeshift home theater (which got turned into an office). While I'm perfectly content with putting the Velodyne sub out in the living room, based on what you say, I also have to replace the tiny white sats that are ceiling mounted in the living room. I suppose I could keep the Bose box out there just for the sats but then I'd have two large boxes in my living room which is a bit overkill, not to mention an eyesore. Obviously I would like to replace them with small white speakers similar to the double-cube stacked Bose speakers that are there now. Any advice on what to replace them with? Thanks also for the link! |

The Velodyne would be an improvement over the Bose "bass module" but an Internet-direct sub like the Hsu STF-2 would be much better.
http://www.hsustore.com/stf2.html
If budget is an issue you can look at the Dayton 12" subs sold at partsexpress.com for about $145 shipped.
I'm afraid that with subs and speakers you simply cannot get the same sound out of a tiny package. With a sub it's easier because you can just tuck it away in a corner or under an end table.
If you absolutely must have tiny satellites, you can always try the packages made by Infinity, Polk, Athena, or (pricier) Orb Audio.

Just do NOT go with a packaged subwoofer, these will never give you the real bass that your DVDs deserve. |

I'm not interested in shelling out more money for yet another sub... so the 10" Velodyne (which IMHO rocks) that I paid ~$500 for about 3 years ago will have to be the new sub woofer for my system if I can't figure out a way to keep the Bose AM working consistently. I'll shop around for some new sats if that's the case. Thanks again for the info.

The Velodyne is light years better than the Bose sub I'm sure, and if you're happy with it that's the only thing that counts.
Replacing the receiver and sats alone will yield huge improvements.
For the receiver, look into the Panasonic sa-xr55 pure digital, $230 shipped from Amazon.com --- there's a big thread on it in the "Receivers" section. Stunning little giant-killer.
Combine that with a $60 Toshiba 3980 from Best Buy and you'll be good to go.
Best of luck! |

Hi guys... I ripped open my Acoustimass 15 subwoofer... to fill you guys in, the base module stopped working suddenly after 5 years of use. I thought the recent power-surge had something to do with it, but upon opening it up, looking at the fuse and in fact even buying a new one and putting it in, realized that it wasn't the fuse that screwed it up :-(
Let's see what I do next. I am however, posting a picture while I had the thing popped open. Might help someone.

I managed to open mine, and it's a blown fuse... Lucky me... Just have to go and buy a new one now... and hope that there's nothing else wrong further... Thanks for all the advice... And don't forget to remove the 2 screws at the bottom, I kept knocking and knocking, it's quite a solid plastic case I have to say!! Then once the screws were out, it was very easy... Cheers! |

I just opened a Bose Acoustimass system ( thanks for the tips on how to open it ). It wasn't the fuse. It looks likes the transformer is good. Next in line are 2 components :
- a BTA01-600S which is a 6A Triac.
- and an MOC3063 which is the optocoupler driving the triac that maintain the power ON.
If any of those are dead the system will not turn on. I haven't tested them yet, but I might just short circuit A1-A2 of the triac to force the system to be permanently ON. It's the cheapest solution. The drawback being that if there is any automatic shutdown, it won't work any more. |

I have a Acousitmass 5 Series II sub woofer with a blown fuse. Never seen a fuse like that before and I can't seem to figure out what kind of fuse it is.
Trying to avoid the $120 service charge from Bose for replacing a blown fuse.
Would appreciate any help.

I have a bose 3-2-1 Sytem and mine was a blown fuse in the subwoofer. After Replacing th fuse the Varistor burst open (probably it could not handle the surge in my area)
After replacing the Varistor I can see 18 V coming from the power unit to my media center. My media center does not power on now. The moment I try to connect the media center to the subwoofer the voltage drop straight from 17.5 V to 5 Volts... I am supecting a short circuit in the media center.
So my Bose 3*2*1 lies in dust. Any ideas how to go about fixing it? |

I have an Acoustimass 15. I had problenms of what seemed liked the sub not powering up (you the speaker bump nothing else).
Opening it up and checking the fuse and tracing power, I found the problem is the pots. The backing spreads on the pot frame, enough so that there is a contact problem with the potentiometer wiper blades inside. This, belive it or not, will cause no power/sound, a popping pulsating sound, and/or a low frequency hum. Reclosing the frame helped, but I will replace the sub with a KLH that kicks butt.
Bose,what an utter piece of crap
I should have known, anyone that doesn't give out specs has something to hide. |

Read everyone's comments about blown Acoustimass units...mine too! All fuses good, noted some 'dark' bits on power control card, but notihing blown. All components buzz out ok, resistors, diodes, triacs, etc. Only thing I can see that truly worries me is the majority of the solder joints are cold solders...talk about quality on a system that costs so much to buy! I am going to break out the sodering iron and solder sucker and resolder...will let you know if I have any joy. Can't really see anything else that would cause problems, short of getting the schematic (yeah, I know, dream on...) and an o-scope. |

I have a Lifestyle 12 system that is 10 years old. Finally it kicked the bucket and I cannot get any sound from it. I suspect the fuse is gone but like almost everybody else I cannot open the damn thing. I tied to identify that famous wheel that some people talked about in this forum but I failed. Does any person has a picture of an open subwoofer case locating this famous plastic wheel? I would greatly appreciate it. Robin Nayyar apparently posted a picture of the open box but I did not find it in this forum. |

Spent 10 minutes reading all reports. Resonably techincal. I have Acc 15 sub. Same prob as everyone else. Six years old. i will have a look and if not successfull in view of cost may just buy new speakers which are needed for stereo only not surround sound. Any suggestions welcomed. Small speakers please |

I have the same issue as dead subwoofer on Lifestyle 15 , no sound at all. It happens after a move. I open the cover and checked the fuse, it seems fine.
However, I have a little doubt on the balck conntector on the CD side (from CD to Sub ). Top of the connector seems broken, but not quite sure if it is that way or broke.
Is it a 2 sector probe like a DC power connector look a like or a 3 sector streao jack like.
My one looks like a 2 sector now.
I would really appricaiate If anyone can confirm how it should looks like. Again this is the black connector along with the red and white ( other side is 8 pin connector).

With the power of google search, i found this forum. After reading the intelligent advice and posts, I found the solution to my problem. My 7 year old Bose LS35 series 2 sub finally gave out. I dismantled the amplifier cover carefully but very tricky. I found the fuse, ran to the rat shack and bought a box of 3amp/250V fuses, $4.99 for a pack of 5. Replaced the old fuse and now I have my sound back. A great thank you for all the intelligent posts and savy responses. |

Hmmm. The number of people who've had their expensive bose system blow up, (just like me) is a little disconcerting.
Thanks to this thread and it's posters, it didn't end up costing me a packet. Although in light of it all, I'll definitely re-consider my next HT purchase...
Thanks again. |
