I have owned the Response 1s, 1sc, 2, 2s, 1.5 and 2.5 and have heard most of the Studios and Tablettes, as well as Response 3 and 3.5 and d38(was importer in country for close to 10 years). All have the typical Proac sound and in right room and with right amplification, they can sing. I prefer the original Response 2, will take the 1sc to island as my last speaker, but dont care much for the 2.5s(big bass and veiled mids compared to smaller 2 or 1scs, but was probably, after the Tablettes, Proac most successful mdoel).
