i recently tried a yorkville combo i tried the xm100 combo it is 100watts which isnt very mutch! but once i plugged it in i was completly amazed at how loud it was and it was only 100watts!! o yea also i guess i plugged myself into the wrong slot i plugged my passive bass into the active possision so i still didnt even get enuff power but it was still loud! the combo i am now thinking of getting is the xm200 which is 200watts and has a 1x15 speaker, or the xm200t which is also 200watts it just has 2x10inch speakers. i would eventually get a extension. what do you think is the best way to go the xm200 or the xm200t? both combos need to be able to play without a extension cabinet for those smaller gigs. can you also tell me what extension cab would go best with the combo you choose.
