You have to say it as it is: MAGNACORE is Larsen's flagship of cello strings. Anyone who aspires to a higher level of technical virtuosity and emotional expression can hardly pass this series. It opens up an unprecedented potential of timbres, combined with the shimmer of novel clarity and brilliance. Magnacore A and D are manufactured on a solid steel core that is spun with high quality precision rolled flat wire. G and D strings are made of a spiral rope core, the wound of which is made of precision rolled tungsten flat wire. All single strings and sets are available in high tension (strong), medium tension (medium) and Arioso. The latter is a low tension version that is combined with medium strings in the set. Larsen Magnacore The perfect set.
