Half the impedance yields twice the power exactly when the amplifier is good enough to not drop voltage due to lower impedance (higher current): P = VxV/R.

@@dandonna852 High current is high amount of electrons flowing and is measured in amperes. Watts is a unit of power and defined as 1 Joule of energy per second. Ohms is a unit of resistance. 1 Volt (V) conducting through a 1 Ohm (R) resistor yields 1 Amp (I) of current: V=IxR (Ohm’s law). It also yields 1 Watt. Power can be calculated as P=VxI. Since I=V/R, you can also calculate power as P=VxV/R.

I don't get this amplifier power doubling thing - let's say an amp does into 8/4 150W/200W But if you then take 8 at 100W then it'll still be able to do 4 at 200W. So it ends up looking like mfr picks either the doubling up marketing or the higher power (into 8) marketing.

Just a friendly suggestion, use comma, I'm not even sure if you're confused or if you managed to confuse your speakers. 😉 Maybe reading about Ohm's law could help you. As a reference when reading that, amplifiers are voltage regulating (most of the time), but need to be able and deliver a decent amount of amperes.

Infinity 9 Kappa - my very first highend speaker, that I bought in 12th grade high school, got me a really quick lesson in speaker Impedance and Current demands. The 9 Kappa's had a minimum impedance of .8 ohms (YES, less than 1 ohm) and a switch on the back which would eleviate the current demands by allowing the speaker to ONLY dip to 3.2 ohms. I ended up having to shell-out (i.e. get a Loan for I was out of money after paying for the new speakers and my new NAD CD playe) a ton of money on a Harman Kardon Citation amplifier - 200 watts into 4 ohms (equally important was the high instantaneous current capability of 120 amps) and could drive the 9 Kappa's even in their extended .8 ohm mode, for which gave slightly more bass / below 35 hz.

I got schooled by a pair of Infinity Quantum 4s. I purchased them in the Summer of 1978, and quickly realized that my trusty Sansui receiver could not feed these ravenous beasts. I shopped for a amp with high current and low impedance drive capability, then connected it to the Sansui's preamp outputs. I broke my budget, but there was no easy way out. I also settled on a Harman Kardon amp( HK 870 ), and the Quantum 4s responded with great full range sound and deep bass.

My speakers have a sensitivity of 84DB and my 65W power amp is more than capable of driving them. Perhaps it’s because the amp is class A. The power doubles for 4, 2 and 1 ohm, which I assume means there is a lot of current on tap. The amp has meters on the front and the most I’ve seen it output is 6 watts, although this is typically around 3 watts.

65watts in class A into 8ohms and the ideal voltage source characteristic you imply, would entail a power output of 520watts into 1ohm load, hence heat dissipation of about... 2500watts, taking class A efficiency into account. The amp would be comparable in size to a washing machine.
