The speakers are probably 9/10 condition aside from that tweeter
Anyway, I kind of want to ask what you would do in my situation. I can find this original tweeter but they're really expensive, since there's a dwindling supply. I could get new tweeters for both speakers, and they might even be better, but then I'd lose the aesthetic of the original speaker. If you were in my situation, would you pay the money to replace the original tweeter or get a new set? If you got a new set, which ones would you get?
Thanks in advance!
The DM600 Series 3 tweeters are available direct from B&W for $81.09 each and that maybe your best bet if you're going to replace the entire tweeter. I would replace both units and it should be a direct fit/swap. There should not be very much difference if at all sonically.
They also sell the diaphragm assembly for the DM600 S3 tweeter for $61.54 and it may very well fit the motor assembly of the DM600 S1 tweeter. B&W is kind of unique with their tweeters, the way they are assembled and they way they mount in the cabinet. So with the modular design the S3 diaphragm may very well fit the S1 motor.
B&W does sell replacement parts for their tweeters allowing a rebuild of the unit. You might contact them direct and see if parts are available, this is sometimes the case even when the complete unit is discontinued. The tweeter part number for the 602 S1 is ZC10111 and the Metal Dome part number is DD01155. It's not that difficult to tear down and replace.
You can also remove the diaphragm from the tweeter body and carefully push it back out.
The tweeter is attached to the cabinet front baffle board using a twist lock bayonet type mount. This is the procedure to remove it.
1. Remove all screws holding the bass drive unit to the cabinet
2. Remove bass drive unit and disconnect the wiring from the spade terminals on the driver. If they are both the same size (they are on older models) take a note of which way they are connected.
3. Reach into cabinet and grab the back of the tweeter drive unit. Twist it counter-clockwise from the cabinet, it should only require about a 90 degree turn.
4. Remove cable plug attached to tweeter unit.
To replace the diaphragm assembly you:
1. Remove the 3 screws from the front of the tweeter.
2. Remove the tweeter diaphragm assembly by carefully lifting it straight up.
3. Replace with spare part from B&W.
4. Reassemble by following above steps in reverse order.
