Hey i was just wondering what the max efficiency of class a/b amps are.
I ask because i am looking at a gladen xl250c4 it is 241w x4 @4 ohms.
On the spec sheet it says the max power consumption is 89A.
241W x 4 = 964w
89A x 14.4v =1281.6W
964/1281.6 = 75.2%
I thought A/B had a max efficiency at somewhere around 50-60%
Is it possible to be this efficient or is one of those posted specs likely inaccurate?
