Loaded with 4x12 inch specially designed Blackheart by Eminence BH1216B speakers and specifically voiced for closed back cabinets, the Blackheart ENG BH412 straight and slant cabs feature that rugged, "we're in this for the long haul" build quality that makes every BHE piece of gear a lifelong commitment to sounding your best, being your best and pissing off your neighbors. Rather than worry about how cheap they can make something (which to them, is like trying to see how ugly of a date you can get), Blackheart send these out your way with metal handles that'll hold their own for years and heavy-duty, metal casters that'll roll while you rock longer than most marriages last these days. These are sexy little boxes that feature meticulous tolex work wrapped around 15 ply (18mm) void-free wood cabs, classically joined and glued.
