P2 planning state
LNGR SUB-12.4 replaces the earlier 2×18PT preview. The goal is a very wide, shallow home-cinema enclosure using four affordable 12-inch drivers and substantial displacement. The port is centred and folded inside the cabinet.
The simulation is a planning model. Port losses, driver tolerances, room gain and maximum output require measurements on the finished enclosure.
