The Flashline Series TFS-900B from Turbosound is a 6,400W subwoofer designed for touring and fixed installation applications. It consists of two carbon fiber loaded 18" neodymium low frequency drivers utilizing specialized voice coils wound on both the inside and the outside of the former for higher magnetic density. This results in better cooling, higher power handling, and improved efficiency. These high power drivers are mounted in a hybrid horn-loaded enclosure which makes use of output from the rear of the cones as well as the front, providing improved high output at sub-bass frequencies. The TFS-900B subwoofer is designed for ground stacking with the Flashline TFS-900H flown line-array loudspeakers.
The cabinet is constructed from extensively braced 3/4" (18mm) birch plywood with multiple recessed handle positions, side driver access doors, and heavy-duty wheels. It is fitted with a stainless steel IP54-rated grille, and is finished in black TourTough coating. A recessed panel at the rear of the cabinet carries two parallel linked Neutrik speakON NL4 connectors for input and link through connections.
