I've been playing through Fearful cabinets for the last year or so and love them. I have a 15/6/1 a 15/6 with electronic crossovers and a 15 subwoofer. Most Fearful cabinets are 2 way or 3 way, they are light weight and play crystal clean and clear. You can hear all of the nuances of an Alembic bass through them. Even at loud volumes they stay crystal clean and clear even the low B string. They say a 15/6 when played loud is as loud as a 4x10. They are said to not color the sound but reproduces what is fed into them. Unless it's an outdoor gig, a 15/6 is plenty, and for outdoors I'll either use the sub or bring both 15/6/1 and 15/6 and can cover most outdoor gigs without a FOH P.A. They may be hard to find in Germany but if you're handy with tools you can build them yourself with plans from the Greenboy website.
