45N12 is a flexible, one box solution for any stage monitoring application , providing rental companies with a ‘one box’ solution for all their stage monitoring needs. Delivering consistent SPL and frequency response within a tightly- focussed area, cabinets can even be locked using an ingenious magnetic locking system to create monitor arrays where more SPL and wider coverage are required.

Key Features

  • World’s first line monitor
  • Can be joined together into arrays to provide a scalable solution for wider coverage and higher SPLs
  • Very high headroom before feedback
  • Focusses coverage only where needed for lower acoustic power on stage
  • Discreet, low profile design
  • Ingenious magnetic locking system
  • Non-slip base with skid system and ergonomic handle for easy repositioning on stage
