I will do an estimated guess when I compare the 12.0 to the Evo 4.2. I know it is an unfair comparison in size but the signatures are alike. The diamonds are clear and detailed but I like the added depth in weight of accoustic instruments and voices on the Evo 4.2. The woofer and cabinet combined with the well adjusted Amt tweeter just give the idea of a drummer hitting a cymbal rather than the sound the cymbal itself produces. Both are fine to me but it is a slightly higher sense of realism. And like the evo 4.2 the 4.1 was really well received in many reviews.
