Yes, but their logic is flawed. That is NOT how it works. If we increase Mms, we have a UNIFORM decreases in high frequency efficiency, but that's it. It has no bearing at all on upper end frequency response. INDUCTANCE is what dictates high frequency response. It is simply a myth that the driver with a smaller/lighter diaphragm moves "faster". After all, if it were moving faster, it would HAVE to be producing a different frequency.
I swear, people really need to pull their heads out of their ***** on this one. This is what happens when people believe illogical 3rd hand info and marketing pamphlets without even bothering to ask if it is true.
Even a little research would reveal the fallacy of driver diameter/mms being equated to drivers sounding "fast" or "slow". The chief limiter of high frequency response is inductance, Mms really has little bearing, as does cone diameter, at least in the case of subwoofers, as frequency response will be dictated by Le, not Sd, given that we are primarily dealing with frequencies below 100Hz.
What is usually the culprit of the drums, etc sounding off is that the crossover point is poorly set and/or the levels are poorly matched. Nothing makes a drum beat sound like shit like excessive low frequency output relative to higher frequency output. If you have 110dB of highs and 130dB of bass, that's the first idiotic mistake you need to correct. If you like the music that way, then you don't like SQ, you like bass with music in the background, which doesn't even RESEMBLE the original source material.
Set your crossovers intelligently, and don't be a dumbass and set the bass at a much higher level. The method of setting gains by finding the front stage clipping point and then matching the sub clipping point to that...is downright idiotic. That is a way to just about guarantee that you won't have anything resembling balanced output. You should set by output level, as the sub is nearly always going to make the amp clip at a FAR higher output level than the front stage is capable of, in many cases the subs send the amp into clipping 20dB+ beyond the front stage.
So fix the crossover and level settings first, and remember that you want to choose an alignment based on what you know you like. If you like "punchy" bass, i.e. a peak in the midbass region, then you want a higher Q alignment, probably 0.9-1.1.
