SUB1

The SUB1 is a high power compact subwoofer cabinet designed to extend the frequency range and power bandwidth of Audio Performance full range loudspeaker systems. 
With a cut-off frequency of 45Hz, the SUB1 is made for applications where the reproduction of sub frequencies is of importance (music, sound effects).
When stacking several cabinets is necessary, the direct radiating loading of the SUB1 provides the optimal use of the coupling effect to increase the low-end sensitivity of a system.
Key features 
  • High power handling
  • 45Hz cut-off frequency
  • Processor controlled
  • Optimal LF coupling
