[quote name='warwickhunt' post='638546' date='Oct 27 2009, 10:01 PM']There's a long running thread over on TB and I've seen something in there about 320w into the combo internal load, which differs from the standalone puma amp doing 260w into an 8 ohm load... don't ask me how they do that.[/quote]
It's because the larger, twin speaker combos have the 500w power section and the single speaker combos have the 350w power section.
In order to get full power from either, you need to plug in another 8ohm cab. The 2x12 and 2x10 are pretty loud as they come, so anyone thinking about splashing on one, don't hold back.
