High end Class D amps?
Look at the specs of the PuriFi modules, which can put out 500 watts into 2 ohms with 0.0003% THD.Look at what independent tested current it can do. Compare the "2ohm wattage" to the "4ohm wattage", and see if the 2ohm can come "close" to doubling the 4ohm, if so there’s no current limiting. If it’s similar or lower, then there is severe current limiting/sagging. Cheers George |
@georgehifi -- It doesn’t matter. It puts out 500 watts into 2 ohms. That’s enough for most users. I consider "doubling" an irrelevant factor. Does the amp generate enough power for the intended use? If so, it’s a good choice (as far as power goes). If not, it’s not. By the way, your statement is logically equivalent to saying that if an amp does put out 500 watts at 2 ohms, it is somehow lacking if it provides more than 250 watts at 4 ohms or 125 watts at 8 ohms. Why should that be a problem? |

Class-D Behringer for just $600us. Let me tell you, that on the Wilson Alexia in an a/b it was trounced by the 40 x times less powerful!!! Gryphon in dynamics and bass control. The Behringer was thin, anemic, weak in the bass and sounded like it was struggling https://www.bhphotovideo.com/c/product/1427354-REG/behringer_nx6000d_6000_watt_class_d_power_amplifi... |
