I was hoping someone could shed a little more light for me on the subject of amplifier output at the various loads (8 ohm, 4 ohm 2 ohm). From what I can gather thus far is that a speaker is rated nominally and actually resistance varies with frequency.....low frequencies having a low resistance value. So if I understand this correctly, then an amp that has a good low end, tight defined bass etc will be able to go down to 4 and even 2 ohms????? Am I on the right track here? I have heard a lot of talk about the "ideal" having power at 4 ohms twice that at eight and power at 2 ohms twice that at 4. Is this correct. And if an amp has only maybe a 30% increase in 4 ohms over 8 and maybe not even stable at 2 ohms, would this mean that it would not have as nice of a low end and tight defined bass??? thanks.
