I've always been a fan of the sealed cab because they seem more punchy and dynamic, but lately have been dabbling with some ported cabs and have taken a liking to them. In particular, the Hiwatt SE4123 4x12 has a small slot at the bottom of the rear panel and that cab pumps out a ton of bottom end !! ..... and it still sounds punchy! I'd love to hear two of these stacked. Another good little cab is Mesa's 2x12 metal grill open / closed back. The bottom is ported and the top is just open back. It's a very loud and in your FACE cab !! Nice bass and a pretty tight tone. Finally, Mesa's Thiele 1x12 cabs. Pretty good sounding cabs for a small package. Ported cabs, Yay or Nay ?
