Audison APK 165 Ω2 is a Prima Series 6.5" 2-way component speaker system configured at 2-ohm nominal impedance for high-efficiency OEM integration and improved amplifier output. Designed to extract more power from factory amplifiers or compact DSP amps, the Ω2 variant delivers increased dynamics and midbass authority compared to standard 4-ohm speaker loads. Prima components focus on real-world vehicle acoustics: shallow mounting depths, controlled cone behavior, and elevated sensitivity for factory door locations and DSP-based tuning. With Tetolon dome tweeters and compact passive crossovers, the APK 165 Ω2 provides articulate vocals, balanced staging, and stronger low-frequency impact without fabrication.
