First post on this forum.

I have a pair of A&R Cambridge Arcam One loudspeakers that I bought new about 35 years ago.

After thousands of hours of listening and countless parties one of the bass speakers has turned a little fuzzy especially at low volume and at low-volume occasionally cuts out for a split second.

I am guessing that it is the speaker that is at fault and that I should source a replacement or possibly a replacement pair as I don't suppose I'm going to be lucky enough to find one speaker to match.

Having never sourced any replacement parts for any loudspeakers or other hi-fi hardware I haven't a clue where to start.

If I can tap into your expert knowledge and if anyone can point me in the right direction I will be most grateful.

Have you swapped the left and right speakers over to see if the fault follows the speaker ? It is possible but also very rare for a speaker to cut out and start working again, should be an easy fix though. The fuzzy sound suggest a loose or high resistance connection.

Have you checked to confirm the problem is not the amp ?? The symptoms you describe could also be caused by a dirty track on the volume control pot or dirty connections on the function selector switches.

I have tried them on speakers one and speakers two on the amp and the problem is the same. I am also running a different pair of speakers on speakers one now and there isn't a problem with them.

I will swap over the speakers from left to right cases in case it is a problem internally in the speaker cases, good idea!

Thanks

Substitution is one of the quickest ways of tracking down the problem. If the problem isn't present with a different pair of speakers then it looks like you've found the culprit.

If it cuts out altogether than both drivers ( woofer and tweeter ) go off at the same time. This points to the poor connection at the input terminals or where the input terminals connect to the crossover.

Another possibility is that either the woofer or tweeter is connected in series in the crossover circuit; in this case if either the woofer or tweeter were at fault then the whole speaker would go off.
