Kef 105.2 broken?

rmleedom · 9th January 2008, 06:45 AM

I have a pair of Kef 105.2 speakers that I am having a problem with. They sound great, but when I increase the volume, the left speaker will cut out. If I turn the music down, the speaker will resume playing. Today I was playing a song with a lot of intermittent bass and when the bass hit, the left speaker quit playing music and instead had a humming sound, akin to too much gain. Did I blow the S-stop or the crossover, or .... All the drivers are playing the same sound. I am using a MESA baron tube amplifier to power them. I had the dial on the back dialed to the 200 watt setting. Any help would be appreciated. Can I bypass the S-Stop if it is indeed the problem?

Swap the L & R speaker cables at the amp terminals.
Which side now cuts out?

Hi

I have a pair of kef 105.2. They will take a lot of power. I find it hard to believe that you have damaged the crossover. I am not famiar with your amplifier. Is it power limiting in some way?

I will switch terminals when I get home, the amplifier is rated at 155 watts/ch. She puts out a lot of wattage.
