Hi,
I've been using 2 sets of S45.2 speakers I bought about 5 years ago, and they've been producing some really sweet music. It's especially nice to pair them with some DIY Class D amplifiers, they match really nicely.
Now, I was thinking about changing the caps in the speakers, and have been reading about them. So my question is:
1. About changing the caps, I just need to buy the kit and then ask someone to solder the caps or I can try to do the soldering myself right? Anything particular to pay attention to?
2. I've been reading about magnets moving off, what exactly is this? I haven't yet opened the speakers yet, but how can a magnet "move off" Isn't it part of the driver itself? If it'd move off it wouldn't make any sound, would it?
3. About the DIN connectors. Are they really OK for sound quality / electric connection? I cannot imagine that little steel pin really is OK, but on this forum the agreement seems to be that they are. My idea would be to change the DIN connector to either:
- leave a hole with internal cables going out of the cabinet, so I'd just attach a binding post to them + heat shrink
- cut a bigger hole at the back of the cabinet and install proper binding posts
I'm afraid both of the binding post conversions would affect the sound quality, as an open hole would change the reflex box or a big terminal would take away from the chamber, so I'm thinking it might do more harm then good.
I just cannot imagine that tiny pin making a good electrical connection, when binding posts are designed for 4mm cables. I'm open to your advices. (p.s. the speakers look really nice, but what should I do with the rubber parts? Should I lubricate them with something?)
1.If you can solder wires, you can replace the capacitors. They sit on a fiberboard - no PCB.
2.Magnets are glued to the metal basket.The glue losens when the speakers are shipped or moved carelessly and the magnet snaps to one side, squeezing the voicecoil, making the driver silent.Do a search in this forum for more info, there's also a few good threads about how to repair the drivers.
3.The DIN connectors are absolutely fine. They are used on B&Os larger amplifiers as well, and as long as youstay under 400-500 Watts per channel, there'll be no problem at all. They are also safer - can't short like bare wires can.It would also be a shame to destroy the speakers by drilling holes.Modifications to B&O rarely ups value.

Thanks a lot, I'll definitely stay with the DIN connectors then. I'll also contact you about the capacitor kits.
