i got a model 126 Acoustic control corp. combo amp with a 15" folded baffle cabinet design. the original speaker just sounds like mud, probabely mostly atributed to the cabinet design. the speaker is original so it is probabely 30 years old. i'm hoping that a new speaker, would help to balance the mud a little. the amp only puts out 100 watts, so i would need a mondo speak, just somethings that with make it sounds balanced. Any input would help. thanks!
