Question about B&W DM605 S2 Speaker
I currently have a Denon 3300 Receiver and everything sounds great until there is a deep bass or typically explosion sound effects in a movie DVD; at that point a loud clicking continues through the bass or explosion from one of my DM605 S2 speakers. I have tried many things and have even changed receivers to a JVC 7204 but still have the same problem. Is my speaker blown? Can this be fixed? Thanks.
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.

Hi everyone having problem with B&W DM605 S2 speaker. The speakers are rated at 8ohm but during playback the impedance drops below 4ohm at low frequencies. It overloads weaker amplifiers and sometimes causes DC voltages to be injected into the speakers. Since the speakers in question are with active sub it appear that some elements on the PCB could be damaged. I would opt for LM431 (Adjustable Precision Zener Shunt Regulator) and associated elements. It could also be the rotary switch (the one used to adjust base levels - 2pole/6way) as contacts weakens over time. Possible solution: 1. switch your amp. to 4ohms 2. with the sub turned off change the position of the switch few times from max left to max right before setting it up in the desired spot.
If the problem persists: 1. replace the switch
2. replace suggested elements checking also KBL401 (Rectifier). TDA7294 (Amplifiers) are usually O.K.

Permanent fix for B & W 605S2 Speaker (loud pop through one of the bass speakers ) at high volume. what i did was called the B & W company in Boston MA , I Spoke with the tech guys and they suggested to send in the powered amp on the back of the speaker, so i went home and unplugged and unscrewed the amp
from the speaker, carefully draw a diagram of the colored wires and unplug them , sent in the amp for repair. Days later they called me and said the problem was in the two switches that control the bass , they replaced them with new switches with gold plated ones (part no SS09393) Cost of 28.00 per switch
email me at firstname.lastname@example.org with any questions
hope this helped out Mark

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?
