You don't see many sealed box cabinets out there. Seems like a couple of the SBX 4x10s and you'd have yourself a more portable version of a 8x10 SVT. Maybe a cheaper and more portable option to the Berg NV610 too. But then again the SBX series seems to be the budget line so maybe not. Anyway I'm intrigued and curious to know what people's reactions are to hearing them.
