Class D is Class D?
Aside from QC differences between brands, is there any fundamental difference between a Class D amplifier made for home audio and a Class D amplifier made for car audio?
As I’m going further along the journey of planning and building out my DIY home theater, it’s obvious that one of the biggest expenses is amplification. But, when I see videos from Williston Audio Labs on YouTube, where Class D car audio amplifiers deliver so much for so little, I can’t understand what stops someone from utilizing these in home audio.
Looking at the Stinger Audio MT1000.1 Class D Monoblock amplifier (1500 Watts RMS), the manufacturer lists power ratings as 1000 watts at 1 Ohm, 700 watts at 2 Ohms, 400 watts at 4ohms, and a huge 1800 watts bridged at 2 ohms. Williston Audio Labs’ testing showed it to meet those power rating and then some (at 1% THD): 1146 watts at 1 ohm, 844 watts at 2 ohms, and 511 watts at 4 ohms. He didn’t have a second one to test the bridged rating, but from the other numbers one could assume accuracy at least, but likely higher results than rated. And all of this is for just $159.
I understand a power supply would need to be purchased in order to use one of these in home, but that still comes out far cheaper than any home audio monoblock amplifier I’ve seen with that many watts. So, what am I missing? Why isn’t this a thing? Is it not that simple?
