Who rates the power output of these things? How do they rate them? I have to get 53Vrms output to calibrate the cylons of my 700 to represent 350 watts, and this thing uses a 20vdc power supply! You can’t get more out than you put in, unless it’s nuclear fusion!
My bro-in-law gave me a TV sound system with five 3” speakers and a sub with a 5” driver on the front- supposedly a 700w system. I opened the sub cabinet and the circuit board wasn’t much bigger than what you find in a transistor radio. 700 watts power consumption, maybe- but not output!
1000 w boom boxes that operate on 8 “D” cells? Yes, I’ve seen those for sale.
I read the reviews on this device and think they were written by the manufacturer.
