Audison APX 690

The APX 690 features an exclusive 40 mm horn dome tweeter that helps maximize efficiency up to 96 dB SPL, as well as an acoustic lens designed specifically for the tweeter to improve high-frequency dispersion


Features:

• Horn-loaded tweeter: 40 mm horn-loaded dome tweeter
  which contributes to its incredible efficiency of up to 96 dB SPL
  
  
• Acoustic lens for the tweeter, specially developed to
  to increase dispersion in the high frequency range
  
  
• PEI (polyethylene injected) super tweeter for amplification
  radiation of very high frequency ranges, which would otherwise be
  off-center positioning, which is common in rear deck installations
  
  
• Water-repellent treated paper cone with a developed profile
  with FEM (Finite Element Method) simulation technology and
  optimized with the Klippel Scan Vibrometer
  
  
• Mobile voice coil made of pure copper, wound on Kapton foil, for
  better thermal and mechanical resilience
  
  
• TPU ball (thermoplastic polyurethane) with unique "triple wave" profile for maximum linearity of deflection
  
  
• Polycotton spider material for reliable performance and
  linear response to musical transients
  
  
• Large motor assembly, optimized with FEM (Finite Element Method)
  technology, for stable control and linear deflection
  
  
• Plates with low carbon content for maximum magnetic permeability
  and high heat dissipation
  
  
• Compact basket, protected by abrasion-resistant and scratch-resistant
  coating, the motor is attached with damping epoxy adhesive
  
  
• High-current quick connection with temperature-resistant plastic
  cover to protect them from accidental short circuits
  
  
• Developed with the KLIPPEL suite.
