The APBX 10 DS, a 10" subwoofer loaded in a 12-litres sealed enclosure, is the line's "flagship". It is dedicated to the highest performing Prima systems, using the AP1 D amplifier for the sub section. The speaker’s mechanical excursion of more than 18 mm provides for incredible authority, while the refined Thiele&Small parameters set-up provides the ideal balance for all music genres.

• Ultra-low profile (5.6 in. / 142 mm) box with sealed design perfectly tuned to fully exploit the APS 10 D driver
  
  
• 2S² (2 Sides/2 Sounds) design provides the ability to choose between Down-Firing mounting to increase the low-frequency extension and Up-Firing install to obtain more punch and definition
  
  
• Leveling feet with velcro inserts included for a secure grip with the carpet while maintaining easy removal
  
  
• SSP (Sub Smart Plug) features both traditional push contacts and a Plug-&-Play terminal block to easily configure the impedance as required and provides a quick release
  
  
• Rounded corners allow easy positioning in the trunk and act as reinforcement to reduce enclosure resonance
  
  
• Special designed cone-dustcap-basket geometry which guarantees a long linear excursion capability (11 mm, one-way)
  
  
• Massive driver motor assembly, optimized with FEM (Finite Element Modeling) for perfect control under high excursion conditions
  
  
• Water-repellent treated paper 10 in. cone, featuring a profile developed with FEM simulation and optimised with the Klippel Scan Vibrometer
  
  
• Specifically developed to be combined with either the AP8.9 bit (2 CH + 2 CH bridged), AP5.9 bit (Sub CH) or AP4.9 bit/AP4 D (2 CH bridged) amplifiers taking advantage of the bass boost feature and integrated parametric equalizer of the built-in DSP
  
  
• Sturdy metal grid included for a total protection of the subwoofer driver
