Apparent conundrum in removal of bi-wiring in B&W DM 610 while retaining channel separation

[tkray111]

I know removal of bi-wiring has been discussed before in this forum and I understand the need to keep the linking plates between pos and neg terminals. However I remain with a puzzle.

The outputs from an amp have L and R channels output both with Pos and Neg wires. The speaker has a total of 2 Pos and 2 Neg terminals. If I link the Red terminals together and do the same for the Pos terminals, how does the separation between the L and R channels remain, since it would seem that each of the two Red terminals are linked and similar for each of the Black terminals, then both each of the Red and Black channels are linked.

I think I may be asking a silly question, but I would be most grateful if someone could explain this conundrum of mine.

Thanks

Tony

I think you may be about to make a serious mistake. On each speaker the bass and upper FR terminals are on the same channel. You must never link the speaker outputs of two channels together or you will cause catastrophic amp damage.

If you don't want to bi-wire, and who does? Then you connect the red terminals of ONE speaker together, and black terminals of the same speaker together. Do that for each speaker. Then you run two pair cable: - red plus black from your amp to each speaker. Do NOT make any interconnection between the left and right speaker, or you will be buying new equipment. If there is only one set of black and white terminals on each speaker, then you can not bi-wire. If you are not biwiring then the jumpers on each speaker need to remain in place.

Thanks a lot, @TLS Guy, for such a rapid and helpful reply.

I wasn't going to go ahead with those connections as I suspected it might be dangerous and so asked the question. I see now it was a really stupid question. My only excuse is that I was trying to do this at the end of a really long and tiring day of dealing with other problems. So thanks for pointing out the obvious solution in such a kind way.

Thanks again,

Tony

You are welcome. Stay around, this is a great forum. The debate can be vigorous at times, but we get rid of serious and obnoxious miscreants.

Bi-wiring in general makes little sense. When you bi-wire, the two speaker wires are connected in parallel at the amplifier. If you use a single speaker cable, then the connection is made in parallel at the speaker using the bridging plates. You end up with the same electrical connection but twice as much cable on the floor if you bi-wire. It's easier just to use one proper speaker cable.

Running two cables to each speaker is only necessary if you want to bi-amp, ie. you use one amp channel for the Low speaker connection and another amp channel for the Hi speaker connection. You need to remove the speaker bridging plates in that instance. Few consumer speakers benefit from bi-amping, though. The Hi channel uses so little power compared to the Low channel that using separate amps has little benefit in most applications.
