Of coruse, I'm not denying that different speakers have different tonal characteristics, I doubt anyone would deny this

The point i was trying to make is that if a speaker is bass heavy for example, then it should sound bass heavy on any accurately recorded music, regardless of genre.
For an equivalent metaphor, lets say a high quality TV natrally has a little too much emplasis on red colours. The result will be that every single movie your watch on that TV will be 'too red' regardess of if it's Shrek, the Matrix, Hannibal or Debbie Does Dallas. It's wont be 'too red' on Hannibal, and 'accurate' on shrek.
Even if Shrek is recorded to lack Red (as a visual design feature), the TV's natural addition of red may make it look accurate to us - however it wont be because it's not bringing out the 'true colours' of the source.
Likewise a speakers specific characteristics or tonal bias should be noticable regardless of the type of music played on it - as long as that music is accurately recorded.
A soft speaker will sound soft on any well recorded music regardless of whether it's rock, pop, dance, urban, classical or electronic.
No matter what music you are playing, a soft speaker will always sound softer then a harsh speaker. Any speaker which is not harsh, should not sound harsh on any music unless the music itself is harsh.
Hence, my conclusion that you dont need to hear a speaker on every genre of music to understand how it sounds, as the speakers bias will effect every form of music the same way. You just need a couple of songs that you know extremely well so that you can pick
how the speaker is effecting the music.
That's not to say that I go to an audition with a single track - I take a CD I've made myself with about 15 tracks I know very well. However, amoung those 15 tracks I may only have one or two different genres - even though I myself frequently listen to at least 4 or 5 different genres. It usually only takes one or two of those tracks that I know (not necesarilly of a different genre) to give me an immediate idea of the speakers characteristics...the others I just leave on there because it's a waste to make a CD with just two or three tracks on it , and because it's boring to only listen to only two same songs over and over in everything you audition
However your point is taken, and as you said we each have our own methods in how we do things - which is of coruse the beauty if being human

From what you said above, could I draw this conclusion; you would say that seeing most cars have similar suspension that should mean they are all just as good at circuit racing as drag racing as each other yeah?
Not at all. the role of a speaker / sound system is to take a static source, and reproduce it (hopefully accurately).
The role of a cars suspension is not to reproduce a static road surface or condition. It is to keep a car securely or comfortably on the ground (depending on the car's focus).
Hence, these two different animals, and I don't believe that the design of a car's suspension has any relation whatsoever to the reproductive capabilities of a speaker
