RE: Harsh vocals in Magnepan 3.7i

Ah, no.

The only way your point would be true is to use Magnepan's misleading specs to the letter. That would require playing just a 500Hz tone into both sets of speakers at the same level, thus eliminating the additional power requirements from the larger bass panels that the smaller speakers do not have. I don't remember the OP saying he was only using a 500Hz test tone.

If you are putting the same amount of power into a speaker that consumes more power in the lower bass regions (i.e. full range frequency, not just 500Hz), the power is being divided across a wider frequency band thus taking power from the mid and tweeters to drive the new additional lower frequencies. The amp has more work to do.

Do you agree that the lowest N octaves require more power than the highest N octaves (e.g. bass panels require more power than ribbon tweeters) ?
Do you agree that the larger panels have more physical surface area to move/control ?
Do you agree that the larger panels have more mass to move/control ?
Do you agree that the larger panels produce lower frequencies than the smaller panels (wider frequency band) ?
Do you agree you don't get a wider frequency band for no additional power (e.g. something for nothing) ?

If so, then then you must agree the larger panels require more power to drive them full range.

The amps I used that worked very well with the 1 series were not able to accomplish the same performance on the 3 and 20 series even though the speakers were all similarly rated by Magnepan @ 500Hz.
