There we go again ...

Hey guys, please do not fight again...

We are all here for the same reason, we love B&O!

Please do not forget this ...

Yes I have read through a lot of threads regarding shimming, both here and other forums , and I understand that there is a divided opinion about this. Although I feel more than apt in handling electronic circuitry, this will be my first speaker job. I know there are a lot of pros and cons, but I have to take my skill into consideration. I belive I will try without the shimming method for this first pair, and trying it for the second pair.

Well said indeed 🙂

I don't want to re-open the debate but I will say this.  I have done a number of repairs on new speaker surrounds without shimming in the past so I know first hand it can be done.  I've never had a repair go bad so far.  However, after using the shims on the last few repairs I will say it provides peace of mind that the surrounds are perfectly in place.  On my first pair of RL140's I successfully fixed the woofers without shims but it was a real bear. I used a frequency generator to gently apply some low frequency signals to help locate the center position. I finally got it and the speakers have worked great but on my next set I will certainly use shims. So for a first set of speakers to repair surrounds on, the RL 140's are one of the more difficult I would say...just because of their tight tolerance.

Again thanks for sharing your experiences sonavor. Highly valued! 🙂 Yeah, it is a though decision, but I think with the right amount of patience and gear one can probably pull it off. However at a later stage I will also try with shims 🙂

Brand new this one, I think it is just about right color, also lens and motor cleaned.
