Lately I've got one speaker with a hum for about 5 minutes after a cold start. It goes away every time after a few minutes. All other speakers are fine. Haven't played around with hooking it up to a different amp channel yet but wondering if anyone has experienced this?

    Likely the amp, not the speaker.

    Yep, or a bad cable connecting that channel. Usually though when a cable goes south, it stays that way. Might be time for a refresh on the amp.

    I was afraid of that.
