What is DC offset and why did I blow my speakers


So I have a Krell integrated and typically play CD's with out problem. I added a turntable and a BAT tubed phono stage and it sounds great for about five minutes, then my sound starts to drop off and two minutes later I've got two blown woofers. I talk to a few people who say that I probably had a DC offset problem and to check the DC voltage at the output capcitors on the phono stage.

In laymen's terms (not an expert here), can someone describe to me what might have happened and what a DC offset is, how it is corrected, etc. I don't want to go through another set of speakers.

And what else might have caused something like this. I replaced the speakers and back to just the CD now without any problems. I really want to get this phono back up and running so what should I do next.

Thanks in advance!

The turntable was in between the speakers with approximately three feet on both sides. They were good quality bookshelf speakers running from an Aries with a Clear Audio Sigma Wood.
