@overthemoon It certainly can 'play', but Imho, for such music ('rock' or similar) there are 'better' solutions.
I believe that Franco Serblin's first intention when he started his company was making speakers that are in fact 'musical instruments' (hence the tribute in shape, form and the name of many speakers that share names with famous violin creators from the past) . His idea was that speaker must comly with 'listening psychology' which ment that ear relaxes and perceives sounds while 'resting' while reaching 'auditory balance'.
So, obviously you can play what ever you want on them, but it is no surprise that many people who prefer unamplified music, classical or jazz, choose his designs as something that brings them closer to the 'real' sound of actual musical instruments.
In that sense, buying SF might not be the best choice for ones who prefer different ('rock' or else) type of music. Of course, somebody might say that good speaker should play any kind of music, no matter of genre, but my humble experience tells me different. (or perhaps I have not heard really 'great' speakers yet)
Also, one should be aware of differences between creations made under Franco Serblin's Sonus Faber (or his new later company 'Franco Serblin') and speakers that were made under new ownership
