20 cm (8") High-End woofer with stiff aluminium cone, solid aluminium die-cast basket and elastic rubber surround. Extremely low mechanical and electrical losses due to vented pole plate, vented damper and capton voice coil carrier. Fast pulse response due to light weight aluminium cone. Suitable for 2- and 3-way high end combinations and as low-midrange driver in 4-way high end systems.
