Welcome to Beoworld🙂

The short answer is I really don't know as these are one of the very few models of the "S" speaker range I haven't owned so I don't know exactly how they should sound.

What I can tell you is that

Thanks and thank you for the welcome.

I had been reading the previous posts... just needed a little push 🙂

Replacing the capacitors will usually improve the top end - capacitors are used in a cross over to filter out the low frequencies and stop them going to the tweeters. An induction coil will be used to reduce high frequency signals going to the woofer. Resistors are used to balance the two or more drivers.

Of course things are sometimes not quite so simple. This is the cross over of my LS3/5a speakers - like the S30s, they are two way speakers!!

My father's Beovox S30's have been defying replacement for more than 30 years now, including when he took them to his local hi-fi shop and auditioned them against some very expensive speakers. The rest of the B&O he bought at the time is long gone. He uses them exclusively for classical music and they still sound stunning.

I have recapped a pair of s45-2's with excellent results.

I used a kit from Martin for my S45-2's.

OK... so the capacitors are now replaced - amazing how quick the postal service is from Denmark to Cornwall is, thanks Martin.

The sharp-eyed will notice that I have merely snipped the old caps out of circuit, and soldered the new ones across their leads. I didn't fancy dismantling the whole unit: that fluffy stuff is foul, and my eyes are still sore from the dust; I wasn't gonna disturb it any more than necessary.

So an easy job - and look at that cardboard comb and four components crossover, compared to the LS3/5a one above!

Result: 
The sound is not noticably much 'brighter' than before, as such: I guess the old capacitors were still in pretty good condition.

BUT the speakers certainly seem much more transparent: I can still hear that there is a loudspeaker, but much less so than before. I know there's a contradiction here, but I presume that frequencies higher than 'bright' are being passed more effectively.

The other improvement is stability of the stereo imaging - things in the centre don't move around any more. Timpani might be a bit clearer as well...

I was sceptical, but am pleased with the improvements as far as I can hear.

Thanks for the advice and encouragement... I might keep them after all... again... ;-)
