I'd really suggest you look at Mesa's Walkabout Scout, available with a 12 or a 15. I never thought a passive radiator would work in a bass amp, but there I go thinking again ... Cool looking, Mesa's terrific tone and construction, not something you see every day.
Eden I believe has recently re-done the Nemesis line, so you might investigate. They recently were acquired by the holding company that owns Washburn, so the usual cautions about companies changing hands whould apply.
