I recieved my 410XST on Weds. and have gotten to use it in a variety of settings this week. I first paired it to my 210XLT on a outdoor gig. Very loud but a bit twangy even with both tweeters turned down to 8 o'clock. Next day did another outside job and used it with my D-115 cab. Very loud with a more round sound. Nice tone! Last night I used the XST by itself indoors. I was concerned about using only one 8 ohm cab with my WT400 (Pushing a 1000 watt cab with only about 250 watts). Gard from Bass Central assured me it would cut it and he was absolutely correct. Ran the gains about where I always do and the cab kicked some serious behind. This cab is a tone monster. It actually sound better by itself than when used with the other cabs. Gobs of bottom and low notes were very tight and defined sounding. I had previously sat in with a guys 410XLT and every once and a while my B string would break up a little. Not so with the XST.
