13 cm (5") low-midrange driver with Polypropylen membran, neodymium magnet and rubber surround which is suited well for uses where very low installation depth and low weight is required but good sound cannot be renounced in the bass and midrange tone area. The basket front has an integrated fabric grille, which makes a real grille unnecessary and protects at the same time the usually bare airgap, as well as the voice coil.
