Audison APS 8D Prima Series 8" 4Ω DVC Subwoofer for Sealed Enclosures (Single)

Audison APS 8D is a Prima Series 8" dual 4-ohm subwoofer engineered for compact sealed enclosures and OEM-integration bass enhancement. Designed for small air volumes as low as 0.26 cu ft, the APS 8D delivers tight, controlled low-frequency response with low distortion and excellent transient accuracy—ideal for sound quality (SQ) focused daily drivers.

The dual 4-ohm voice coil configuration allows flexible impedance matching for factory amplifier retention, Prima amplification, or DSP-based multi-channel builds. The APS 8D pairs optimally with Audison Prima amplifiers for OEM+ system architectures requiring stealth installation and controlled sub-bass reinforcement.
