Audison Prima

Audison Prima is designed for car audio enthusiasts who want components that integrate cleanly with OEM systems without sacrificing sound quality or boot space.

• Ultra-low-profile sealed box (142 mm / 5.6 in tall), tuned specifically for the APS 10 D driver.
• 2 Sides/2 Sounds: choose Down-Firing mounting for extended low-frequency reach, or Up-Firing for more punch and definition.
• Levelling feet with velcro inserts included for secure carpet grip with easy removal.
• SSP (Sub Smart Plug) offers traditional push contacts and a Plug-&-Play terminal block for easy impedance configuration and quick release.
• Rounded corners aid boot positioning and reinforce the enclosure to reduce resonance.
• Cone, dustcap and basket geometry engineered for 11 mm (one-way) linear excursion.
• Massive motor assembly optimised with FEM (Finite Element Modelling) for control under high excursion conditions.
• Water-repellent pressed paper 10" cone, profiled using FEM simulation and validated with the Klippel Scan Vibrometer.
• Designed to pair with the AP8.9 bit (2 CH + 2 CH bridged), AP5.9 bit (Sub CH) or AP4.9 bit/AP4 D (2 CH bridged) amplifiers, making use of their bass boost and integrated parametric DSP.
• Sturdy metal driver grille included.

The APBX 10 DS is the flagship Prima subwoofer enclosure, built for the highest-performing Prima systems and intended for use with the AP1 D amplifier on the sub channel. Mechanical excursion beyond 18 mm delivers strong authority, while the Thiele & Small parameter setup balances performance across all music genres.
