Linn Kan 1 woofer problem

    One of my beloved Linn Kan 1's is breaking up (a cracking sound) at higher volumes. It does this very rarely but the other Kan does not have the same problem at the same volume on the same piece of music, and powered by the same side of the amplifier. It's either the woofer or the crossover. Any ideas would be much appreciated. These are very early Kan's, however the woofers were replaced with a new correct matched pair about 15 years ago. Any insight or advice would be much appreciated. They still sound quite good. actually they sound extremely good.

    This can be caused by fatigued braids, causing a poor connection between terminal and voice coil. Not uncommon in drivers with a bit of mileage on them.

    Thank you. A fatigued connection makes sense. It is likely, given the way this breaking up sounds. I first thought it was a loose banana plug. I will take it apart one of these days and have a look. I think I could repair that problem. At normal volume levels the speaker is fine.

    Sometimes you can replace braids without removing the cone assembly, but with a small, steel-chassis driver like the B110, may not be accessible.

    Could be down to cone sag. Try running the offending speaker upside down for a while; perhaps using a same dimension sheet of ply Blu-Tack'd onto the top to prevent spike damage from Kan 2 stands, should you have them.

    One of mine was acting up like yours, so I ran both upside down over a few months, and subsequently stored them upside down in a hot upstairs room over the summer.

    If the problem seems to correct itself then consider remounting the bass/mid after rotating it 180º.
