My DC3 combo speaker is blown. .. I'm still use the combo with the speaker disconnected and running the 8 ohm jack out to my theile or my open back C90. question is... will the C90 speaker drop into the DC combo? will it fit? I know they're both 12 in. speakers, but the magnet is bigger, screw holes appear a little different.. anybody else had success with other speakers other than the V30? It's just a pain in the *** to carry the combo and an extra cab to small gigs.
