Top two most important sound qualities

Good.

@gladmo  : What I suggested can't do it with out an external crossover or a subwoofer with not only low pass crossover but with high pass too, this is the one that can take out from the Aerial woofer the bass range below 100hz and puts the IMD at way lower level. With out a high pass crossover filter it does not matters what you can do with one or two subs in favor to lower IMD: just can't do it.

Dear @gladmo : " a consequence of minimized distortion. "

Btw, you can put at minimum the IMD in your system/speakers taking out the frequency bass range below 100hz on your Aerial's because the woofers crossover a little high at 400hz and the IMD down there is higher than ideal. The low bass dvelops high excursion on those woofers that afects at significative level all the frequencies above 100hz and this IMD goes against the mid range and high frequency ranges. You neeed to clean up down there, remember that low bass harmonics affects the overall quality speaker response.

To do that you only need not one but 2 self powered subwoofers with high and low pass crossover filters. Worth to do it with great rewards.

Dear @fleschler :  Rhythm and anynother characteristic  is a consequence of the quality level of those transient response/time decay ( that's part of that TR ) / dynamic power.

Rhythm is a controversial characteristic , obviously is critic in MUSIC as hrmony and other important characteristics and per sé depends of the overall score individual players. It's not easy to explain it but we know that " rhythm " when we are listening:

" The quality of rhythm is the quality of life; however vitally composers conceive their music, they must depend upon performers to recreate it rhythmically. "

""  After all, metres like the spondee, ♩♩, and the dispondee, ♩♩♩♩, need an accent on the first beat to keep their identity. Notwithstanding the opposite tendencies of metrical organization and stress accent, however, some metre is obviously subject to stress, so that metre and time measure become very closely linked, as in the scherzo of Beethoven’s Ninth Symphony, where a measure has a strong first beat and at the same time follows a metre. ""

Where MUSIC start other that the composition it self, well start at that or those first beat or beats by the different players in a group or orchestra the rhythm is " formed " by those transients/decay time and each dynamic power. In MUSIC all is important and not easy to define with presicion which is the more important characteristic and that's why could be so controversial.

Transients and dynamic power always exist but not always with that " rhythm " that each one of us are accustom to and I can tell you that my perceived rhythm in a specific score could be different for you or even me or you can say: no rhythm here.A good rhythm is when our body is just " dancing " it's when we really are enjoying MUSIC and not only lisnet it but as I said is a " consequence ".

Is so delicated that issue that in a home system a not so good room treatment could make a poor rhythm when the same score in other same system well room treatment the rhythm could shines.

Dear @gladmo : Transient response/dynamic power ( both directly telated and we can’t aisle each from the other) and very very low every kind of room/system developed distortions.

Which the main difference between live MUSIC and home reproduced sounds?:

for me precisely transient response that develops the MUSIC dynamic power and with dynamic power I’m not refering to SPL. Each instrument played at any SPL has its own dynamic power. Transient response/dynamic power is what develops the overall natural tone color in live MUSIC where between you and the MUSIC source exist almost only the air. For me all the audiophile adjectives for any room/system characteristics comes from there added by several kind of distortions that puts several kind of " colorations " to the whole room/system tone " color ".

To stay truer to the recorded source we need those characteristics before looking for any other. We need to put at minimum evry kind of distortion developed at each link in the room/syastem chain, it helps. 

Regards and enjoy the MUSIC NOT DISTORTIONS,
