Hi Mr. Cat,
Well, R2's are very good indeed and insane VFM at that price. I don't think you'll find a better all-round floorstander for under £350. The real wood veneer looks stunning and build quality is superb.
I cannot fault their performance with classical, vocal/acoustic and R&B. Bass is not as slow as some would have you believe. Mine are mass-loaded (14Kgs each), port tuned, top weighted (10Kgs each) and about 2 feet from the walls. The soundstage is rich and spread fairly wide. The twin 5 inch woofers produce plenty of bass, almost as much as my dedicated sub! The unloaded cabinet did colour the music a bit, but this can be reduced using the methods described above.
However, I would agree with some reviews that these speakers don't "rock". This is the only, (small) criticism I would make. The upshot of this though, is that they do not fatigue either.
What sort of amplification are you planning on using? They would work well with bright & punchy sources/amps to help balance their slightly laid-back manner.
Very highly recommended.
