Let’s take a look. You have an MC611 and a 1.25. Their sound signature is quite similar but the dynamics, bass and everything else imaginable to your ears is galaxies better with the 1.25. While I don’t know the technical reasons why, I know for a fact it is incomparable better. So in this case, the one watt story and why you would need another 1199 of them more makes perfect sense.
Why do speakers improve with more powerful amps?
So, if I have a solid state amp that more than adequately powers a speaker, why do people recommend a larger more powerful amplifier to improve things?
Why do more powerful amplifiers impact speaker sound quality in a favorable way? Is it because more power is reaching the speakers? Mid and Tweeter drivers I was told receive a reduced signal versus bass drivers which receive relatively more power via crossovers. All for the purpose of balancing a signal going to the various drivers.
