Hey just bought a used B&W home sub model ASW CDM. This is my first sub and still not sure how everything is supposed to be set up. It didn't have a power cord so I'm just using an extra computer power cord. Brought it home but it won't power on.
The guy already told me he'd give me my money back, but $200 for a sub that retailed at $2000 I'd really like to get this thing fired up. Does anybody know of any simple tricks or repairs that can be done? Switch out fuses? Use a special power cord? Maybe it's not set up right? If anyone knows about what might be the problem then please let me know what you think. Thanks.
We had a poster with the same problem with one of those. Unfortunately B & W do not have an on line user manual for that sub. May be there is something strange about them.
I would do this, plug it in, and then connect a CD player directly to the input. Advance the volume and see of you hear sound from it. If no lights or sound it is dead most likely.
I would call B & W support at that time and see what they advise.
The sub the other poster bought had not been powered up for a long time and appeared to be dead. This makes me wonder if those sub amps don't have a cap or caps in the power supply that fail after not being polarized after a prolonged period of non use.
If you do open it up and look for blown fuses, only replace a fuse with one of the same value, and blow characteristics. If the fuse blows again right away, do not replace it. At that point it will need professional attention.
