Even if your amp could accept al three this simply means that both larger canes will be subject to failure.
Thanks Paul and everyone else.
I left out important information, I do not run more than 2 cabs at a time, the 3 cabs are 8 ohm. I was trying to say that I hear the same results with either cab which points to either a non-issue or an issue with the head. I am just not familiar enough with bi-amped cabs to know what to expect.
Paul, from your message I gather that you think even running the 410 with another cab would damage the other cab's cones?
I am using the cables that came with the cabs, I have 4 cables, all of them display the same low output out of the tweeters.
I am using 2 Fender basses, 1 P-Bass and 1 Jazz-Bass both with Chromes flatwound.
I am trying to figure out if there is a problem so that I can get GK involved in case the head needs service.
Thanks again for all your responses.
