That birthsheet is the real deal, this guy would not photoshop it or anything, i know its weird and thats the the owner thougth as well, just thought id let you guys see it for yourselves
i agree with all other's i've never seen any of the new RF amps with lower power @1ohm vs. 2ohm. to your question of amps that do same power at 1ohm and other loads, the new JBL amps do. the bpx 2200.1(my sub amp ), does more power at 4ohm than at 1, plus you're more likely to see 4ohm than 1.
Seriously? I know I haven't seen as many birthsheets as you have, but I haven't seen any with much below 75%. Christ, I could pick up a class A/B and have quite a bit more than 60% efficiency.
as you can see on the birthsheets from the t30001's they all 3000w at 2 ohm, and few hundred watts more at 1 ohm, not one did more power at 2 ohm, but imsure there could always be a few amps that have done it, im sure its not impossible
^ That is from a guy on here trien to sell his t20001 thats what the birthsheet says. If i could do it all over id buy this amp. Its a 2 in 1 deal basically
