The 0304N OEM MCMA (Multi-Cell Micro-transducer Array) planar speakers from FPS are the second largest of all the FPS OEM transducers. The 0304N is ideal for column line arrays, small intercom systems, digital signage, POS displays and TV and PC speakers.

All MCMA transducers are passive so external amplification is required. The 0304N speakers handle up to 7.5 watts RMS (15 watts max) at 4 ohms. The 0304N is the second largest OEM transducer available with just over 11 square inches of surface area the planar effect is prominent but dramatically enhanced when arrayed. FPS builds all their MCMA speakers by embedding an array of voice coils directly into the diaphragm that correspond to an array of powerful neodymium magnets. The 0304N speakers have 12 voice coils and 12 corresponding magnets.

Some of the benefits of using the 0304N speaker over a conventional cone speaker with similar specifications are; significantly less mounting depth and back volume is required, MCMA have minimal acoustic feedback, much faster transient response, dipole capability and high resistance to water and temperature.
