Not nuclear but if my amp had anymore power they just might be... I thought the 2x15 cab would be really lose and muddy sounding but its not at all, it actually is pretty tight sounding and pretty smooth. The V30's in the 4x12 caught me off guard because i am use to my marshall 1960B cab, so far im pretty happy with them, i noticed they clearer the more you turn it up, overall im pretty happy with them. I also picked up a new bass head for my bass rig. Its a peavey t-max 500watt bass head, it sounds pretty good and through my randall 2x15 bass cab it shakes my house pretty damn good.
