I never tried the Walkabout with the Bassic.
That is a superb match IMHE. I had a 4 Ohm Arnopol composite Bassic 15 with the Faital driver and like a twit, I sold it (because I wanted to practice through it to tunes and wanted a tweet for that). I had ordered it specifically for my Walkabout.
Not only did it sound great, but the sensitivity and power handling were an optimal match between the 2.
