4.5 in. Slit Paper Cone Midrange

Scan-speak Revelator 4.5” Midrange

The 12M/4631G is a Revelator driver using the “slit cone” technology. Some of the slits are used to control cone resonance and the other set of slits add rigidity. This speaker also has the new dynamic linear suspension for lower compression and higher linearity. Every facet of this driver is designed to reduce resonance in all structures. A neodymium magnet has been chosen to reduce the depth, yet increase the magnetic energy. The short field length of a neodymium magnet also allows this driver to by used for A/V.
