Unfortuantely, these were built to essentially be replaced rather
than repaired. More of the same attitude from Bose I'm afraid.
It sounds like it is time to go out and find some truly decent speakers.
B&W, Mirage, and even Klipsch make very good speakers that cost a fraction
as much and deliver far better sound.
802 specs:
13*20*13 inches
Response: 55-16Khz(+/- 3 db) - ouch this is awful.
Sensitivity: 92db
This is dreadful. I can get a pair of $300 speakers that will
have better response and clarity. 55-16khz? Ouch.
If loudness is all you want, then even Cerwin Vega does better.
Their speakers have lousy clarity, but they are loud and inexpensive
and still sound better than the 802s. It really isn't hard to get
better sound than the stuff BOSE puts out.
The guy never said that he was using those in a home stereo. What if he
used them for... sound reinforcement?
Mirage as rock n roll band PA... Yeah right!
BTW, the 802 don't have any crossover because all the drivers are full
range. Maybe he was talking about the external electronic Bose
controler box?

I re-read the posting - he is talking about a "box" that he can't
open, so evidently so. Unfortunately, BOSE is not known for ease
of servicing, so other than hacking it apart forceably...
Sorry for any confusion. I am talking about the 802 speaker box
itself.
The reason I got these in the first place is they were cheap used
($400 for the pair) and my buddy already had a full system with 802's,
controller, and subs, that he used for DJ and PA. I was looking to
supplement what he had for my own use.
I did have a second thought today about calling it a Crossover. It has
two yellow cylinders, one larger than the other, which remind me of
capacitors, mounted to a circuit board with wires running out to all
the drivers. There appears to be a couple other parts, one which is
the offending dead part, but it's hard to see without unwiring the
drivers. I'm wondering if I can figure out what the part is, maybe I
can somehow solder the new one to the exposed leads.
I'm probably gonna put either the whole speaker or the drivers on
Ebay. People are bidding on broken stuff I have like it's practically
brand new! I had to re-read my listing to make sure I mentioned DEAD
often enough in the ad!
Thanks for your help,
Todd

IIRC, the Bose 802 does contain a few capacitors (to remove some of the
worst peaks/bumps; the rest is left up to the "controller"). These caps are
accessible after removing the drivers. You should then be able to remove the
capacitor and replace it with a new one. Use the working speaker to find out
the size of the cap(s).

Upon further inspection there are two blue caps plus the two big
yellow cylinders. I was able to solder the leads from the dead cap
together to get some sound, but it was very thin, and only 4 speakers
worked, so I decided to just remove the drivers as spares for the 3
remaining BOSE 802's. Fortunately none of the remaining drivers have
foam surrounds, so I shouldn't be needing to replace them except under
unusual circumstances.
Thanks for your input,
Todd
I would like to see a diagram if you could draw it out. I never was aware of
other components. Its also interesting that you have no other foam surounds.
Might the other boxes be wired differently? Could these be really old, like
early 70's?? To my knowledge, the old non foam types required different
box tunning, even using a closed box system. They are not interchangable.
The older ones were "acoustic suspension" somewhat.
Even if foam looks good, you should be able to really stretch it without
breaking before gettting any real life and volume out of it. The only thing is
to use new foam or convert to some other material.

Could you re-ask the question- are you talking about the X-over in the back of
the cabinet or the external equalizer? I own a pro music repair shop in
Manchester, and know about these things!
