Question about Speakers & Subwoofers
I toppled one of my speakers that sit on a stand, and the can that keeps it upright on the stand broke, so now I need to get in there and fix it.
Here is a pic of the bottom, where you can see the broken bit inside. There are no screws under the white felt dots.
Here is the back; you can see the holes for the two screws.
And just in case, here are the front and top:
I have tried pulling rather hard and also using a screwdriver as a lever (you can see that I've broken the plastic in a couple of places in the "Front" picture).
Any ideas about how to take this one apart?

HI you need to hold the clip in place with a strong narrow long device such as: scissors, tweezers..... and then push them together a coupla of tries and you'll make it good luck

It may not be only wires loose; the speaker(or speakers) may be damaged.
The common 'dynamic' speaker has a centered magnet in an assembly that extends the field of the magnet around a coil of wire on a form called the 'voice coil' that is firmly attached to the cone which moves in and out to 'pump' air and produce sound.
The clearances (gap) between the magnet assembly and the voice coil that sits in a narrow space between the magnet and the outer field piece is very small and critical.
Once positioned in the factory, glue is used to keep the field assembly from slipping and rubbing against the voice coil.
A strong shock will break the glue bond and, if severe enough, clamp the voice coil so it cannot move freely any more.
Since the Bose is a quality product, the cabinet may be assembled with glue and screws that are concealed.
If you know someone with a simple multimeter, they may be able to check at the terminals to see if there is any continuity from the terminals to the speaker.
If it doesn't have any, then perhaps only a wire is broken between the terminals and the speakers.
There is with high probability also a filter inside that separates the frequency range and sends the signal to separate speakers that produce different ranges of sound.

I had the exac same issue. It started out with buzzing sound, but then quickly evolved into blowing the main 250V 5 Amp fuses immediately. I sent mine to ABTechservices.com and they found some blown resistors and leaking capacitors. I'm waiting to get it back (shipping to me now), but supposedly they have replaced and tested and all is working well. I'll let you know how it turns out.
The price they charged me, including return shipping was $187.50

Well, so far so good. I reinstalled the newly repaired amp and fired it up and so far, so good. Ran it through about an hour of fairly intense break-in tracks and then ran it through about 2 dozen power up and down cycles to try to get it to fail (better now than a month from now and have to fight them on backing it up).

There's a fuse input just underneith the mains input plug.A small screwdriver will open the small latch.You can get new fuses at Maplins.

"Subwoofer is designed to be used in the upright vertical position only. Do not use it in the horizontal or tilted position."
I believe the speaker is downward firing and is designed for a nearby (floor) surface. Perhaps if it faced the wall at the same distance...
Of course, you can do whatever you like with it and it may sound just fine to you, or as good as possible within the limits you have to work with.
