HDS 182
182 WR 33 102 SD AL LS 8 ohm    -    Order ID: 850439

A high End mid-woofer with rigid aerodynamic cast aluminium basket profile and ventilated spider. The cast basket provides the necessary sturdy base for the magnet structure and suspension and allows for long excursion of the cone. The spider is ventilated to achieve the lowest possible compression and to allow air to flow freely to create a cooling effect for the voice coil. The design of the basket front allows for very slim box designs and the edges are chamfered to re-duce the necessary amount of counter sinking. The three or five layer sandwich cone improves accuracy and consistency of sound reproduction over the entire frequency range, creating a more "musical" driver.
