This is a first serial product specially designed for professional use in the street stock classes of SPL competitions, where is very important to achieve ideal balance between a high-power magnetic circuit and a lightweight moving system with a large effective cone area that provides a high sensitivity of the subwoofer. Literally, every part of this product was tested in real competition SPL systems, as a result of which we created a highly effective tool for achieving world records.
