FBT Jolly 5 BA are absolutely incredible, 7 pounds and 80 W RMS per speaker, I haven't ever had more efficient speakers. And they do have warm upper bass frequencies. The Mackie is stated to start from 100 Hz, the FBT from 80 Hz. I have accompanied a classic soloist for operettas using symphonic sounds (strings, woodwinds, french horns, piano) with these speakers alone for an audience of 50 people, absolutely clear, warm and loud.
Now, the successive model has been released, FBT J5A.
