I took my SWR Workingmans 10t speaker in for service and just got it back.(Blown woofer replaced). When I plugged it in with the Workingmans 10 combo the volume is less and there is LESS bass with the 10t plugged in. Is there a problem with the speaker output on the combo (perhaps frying the 10t's woofer originally) or is the phasing of the two cabinets opposite (would that even cause this problem)? The repair place is closed today and Guitar Center (the original seller and middle man in the repair transaction) was not helpful. Ideas?
