Field Coil Driver Units Speaker Systems SIT Amplifier

Field Coil type Electro Dynamic Drivers
Maxonic philosophy in development of speakers is "to be faithful to the original sound, and to ideally reproduce music". Perfect dissolution of time lag and phase contrast in reproduced sound wave, and ultimate sound image orientation. All these have been realized by the shape, cross section of which is as shown below. The 'Field Coil' type driver ideally emits sounds from a single plane and presents ultimate sound stage unachievable by a permanent magnetic type speaker.

Field Coil Coaxial 15" Full Range Driver
World first perfect synchronous coax in field coil category, world heaviest full range unit
Tens of years ago Maxonic was marketing the famed DS-405 driver. The DS701 inherited the basic technology to position mid and high range diaphragm from DS405; the diaphragm sits coaxially and and in phase, and replaced permanent type to field coil type magnetic circuit. Labors of Hercules have been achieved in the DS701.
