Have the speaker used as a replacement for the defective Bag End Speaker in a SWR Baby Blue bass amp that I use mainly for amplifying an bass. I'm very satisfied with the sonic result. Subjectively, you will hear no difference to the original, which may also be because of the fact that SWR also Eminence speaker has been used in a later series of Baby Blue. What they were, however, unfortunately, did not identify themselves.
