| Enclosure Materials and Construction |
| 3/4-inch (19mm) thick MDF construction with 1-inch (25.4mm) thick MDF front panel with radiused edges to minimize diffraction. |
| Proprietary exponential wave guide for controlled, wide dispersion from high-frequency driver. |
| Internal "H" brace adds to cabinet stiffness. |
| Open cell adiabatic "foam fill" acoustic damping material absorbs internal reflections, preventing delayed sound coloration. |
| Flush-mount connector system allows monitor to be placed against a wall without need for connector clearance. |
| Transducers |
| Low-frequency driver |
8.75-inch (222mm) die-cast magnesium frame, mineral-filled polypropylene cone, oversized magnet structure, and over 16mm cone excursion.
|
| High-frequency driver |
1-inch (25.4mm) viscous edge-damped aluminum dome with ferrofluid-cooled voice coil.
|
| Passive Radiator |
6-inch x 12-inch (152mm x 305mm) elliptical flat cone composed of aluminum honeycomb/phenolic with variable thickness filleted edge neoprene surround, mass-loaded, acoustic insulated.
