Amplifier circuitry-4 ohm vs 8 ohm
Obviously there are different wires leading into the four or eight Ohm taps on the back of an amplifier from the one amplifier. The single amplifier at some point splits the signal going into either one of these Ports. What differences are there in the circuitry?
Maybe this will help me better understand the difference between these two taps. I believe 4 ohms is a wider more open path for voltage to flow. So when you're speaker attempts to go lower, which requires more power, the 4 ohm more easily allows this to happen with a better outcome. Or maybe I got this wrong.
I have ARC amps from 1995, 2018 and 2023, and they all have 16, 8 and 4 ohm taps. My ELS speakers impedance curve indicates about 30 ohms at 20Hz and 3 ohms at 20kHz. The 16 ohm taps sound excellent. The 8 ohm taps do too, but with a different balance and therefore dynamic. @emergingsoul: I doubt any two amps, especially a tube amp and a class D amp, sound "exactly like".... |
Very interesting, you make up above. It seems the impedance curve of a speaker is very important in assessing Ohm range throughout the frequency range. And there by it seems selecting the proper tap somewhere within the ohm range on the curve would influence how each tap may perform.
Very important and I’m gonna get the impedance curve for my speakers which seems a good idea, because I like to think I’m somewhat smart about this sort of thing albeit very slow |
