Ballsy amps, as far as current delivery is concerned, double down (they deliver 2x the current into 4 ohms that they deliver into 8 ohms & 4x the current into 2 ohms). For example 300W into 8 ohms, 600W into 4 ohms & 1200W into 2 ohms.
Amplifiers: High Current? High Voltage?
I've seen alot of mention about current-based and voltage-based amplifiers, and I am confused. I thought all amplifiers recreated the wave form by varying voltage, and their interaction with the speaker (and the impedence characteristics between the two) dictate what current is drawn. I understand that the power supply of some amplifiers is less current restricted than others, but my (current) understanding also says that all amplifiers work by controlling voltage. Is there really such a thing as an amplifier that controls current rather than voltage?
