Back on topic, I have both 6000 and 4000 speakers at home, and if I had to choose just one pair, it would be my 4000MK1 everytime.

Ditto!

4000 Mk1!

I have both BL6000 & 4000 mk1, prefer sound of 4000 which also have a very flexible bracket mounting system. If you can go listen to both of them

There are certainly some speakers that present sound in such a way that they will typically sound very good when genre XXX is played through them, but they will struggle with other things, so that is perhaps a weakness, not a strength.

If a speaker cannot realsitically reproduce a full orchestre playing a bombastic piece like, say, the 1812, then the same speaker will also struggle with a full on rock band like Nirvana.  Musically distant, but requiring similar depth and power to be recreated at home.

That's exactly it. All loudspeakers (and hifi components for that matter) have their weaknesses/flaws. These can be more evident with some kinds of music than with others.

Tony Andrews of Funktion One talking about this issue:

alex - indeed  "All loudspeakers (and hifi components for that matter) have their weaknesses/flaws"  .... back in my Linn/Naim/rega days, I spent many many demonstrations trying to clarify this to would-be purchasers.

A boomy speaker has a fault - it booms !!!  So, certain recordings may, by chance, sound great.  The flaw in the speaker can either emphasise a trait people want  ( say deep bass in a dance or organ track ) or it can compensate for a recording flaw ( the "boom making up for an otherwise tinny, bass light recording ). 

However, most things will just get the "boom" imposed in a detrimental way.

Ultimately, a system should have no sonic chracteristics, it should just reproduce what is put in - which is why higher end audiopile amps haver little or no eq or attenuation. 

In beolabs, the MK1 4000 are, imo, a very nuetral sounding speaker.  They don't have the very deepest bass ability as they simply can't move that much air - but the trick is to not struggle to do things and end up doing them badly.  The 4000 design does this superbly - obviously a very good match of drive unit/crossover & cabinet design that just "works"

I love mine.  😎

Alex - if your up in Manchester, try and get to a gig / club night at the ( revamped) Band on the Wall - the audio system in there is astounding.  😉🙂
