The Ti-SUB is the installation version of the T-SUB and only differs to the road version in the mounting hardware and cabinet details. It can be used to supplement the LF headroom of the Ti10L and Ti10P cabinets in various configurations. The Ti subwoofer cabinet is an actively driven bass-reflex design housing a long excursion 15" driver with a neodymium magnet. The cabinets are mechanically connected using rigging links on both sides of the cabinet front which slide out when needed, and with a central splay link at the rear of the cabinet. All necessary rigging components are mounted to the cabinet. The Ti-SUB can also supplement the Ti10 loudspeakers in ground stacked applications where the Ti-SUB can mechanically support them. The Ti-SUB cabinet is constructed from marine plywood and has an impact resistant paint finish. The front of the loudspeaker cabinet is protected by a rigid metal grill in front of an acoustically transparent foam. Mounted on the rear panel are two NL4 connectors wired in parallel.
