Just bought some B&W DM605 S2 Speakers and one of the transformers is broken is this difficult to fix and expensive?

If that irritating noise only comes from one of your speakers even though you've changed the amplifier to test whether it continues, I think the problem must be that the relevant speaker is blown. By the way, have you ever tried to switch left and right speakers instead of changing the amplifier?

When you play to loud, the sub element hits the magnet and thats the sound you are hearing. Nothing wrong with the speaker, but you could damange your sub element doing this several times.
Solution, turn the volume done.
The speakers sound great, but remember there are only 2 7" speakers, they cant produce an earthquake. For that you need bigger subbs.

SOURCE: I Need values of resisters R-82 and R-85.

more than likely there probably just fusable resistors wich are just low resistance resistors normall 1-10 ohms designed to burn out if current draw is excessive ive had alook everywhere for the schemtaics for this and i cant find it sorry i can't help much,ben

Testimonial: "Thank you. It does make sense since output I C package was shorted."
