Another one for skeptic or anyone else. Amps, watts & volts ???
Hello, My moniker says it all. I have a 60 wpc receiver & I would like to know what travels through my speaker cables. As I turn up the volume do more watts go through the cable? Is it AC or DC current? Also, how many volts travel through the cables or is that dependent on the volume level? I have alot of questions. Thanks in advance, d.
Mash? is that statement for me?
You seem to have a pretty sophisticated answer for someone who doesn't seem to know that speaker parameters vary by the millisecond. Impedance constantly fluctuates meaning the amplifier has to constantly adjust to a moving target. Add to that capacitance, inductance, back EMF from the woofer, and phase angles...you have a real mess you are dealing with even with an "easy" speaker load.
As far as an amp acting as a perfect voltage source...sorry. Circuit impedances in the amplifier preclude that from happening. What MF and a lot of other companies do (especially car audio) is downrate the 8 ohm rating to hit a doubling at 4, or in the case of Krell and the like, find the output into 1 or 2 ohms and figure back from that. It's fudging downward, not up, so you aren't ripping anyone off, understating power output is not illegal, overstating is...somewhat.
