The Super 30 series is also handcrafted from the same high-quality materials as the Custom series. However, the 30 spirals used provide more articulation and responsiveness. Compared to other wide format carpets, the Puresound Super 30 carpets create that distinctive, penetrating sound without dampening or sacrificing the natural sound of the drum.
