Its dual 4-ohm voice coils provide flexible wiring options for compatible amplifiers. It is intended for use in a compact sealed enclosure rather than as a free-air or loaded-box replacement.\u003c\/p\u003e\u003cp\u003eWith 250 watts continuous power handling and 500 watts peak power handling, the APS 8 D is suited to systems that need controlled low-frequency support without requiring a large subwoofer cabinet. Its 83.5 dB sensitivity and compact-driver format make correct amplifier matching and enclosure design especially important. The driver is designed around sealed-box use beginning at 7.5 liters.\u003c\/p\u003e\u003cp\u003eA 79 mm mounting depth helps the APS 8 D fit locations where a conventional full-depth subwoofer may not clear the rear wall of the enclosure or available vehicle structure. Audison uses a cone, dustcap, and basket geometry intended to retain useful linear excursion in this shallow format. The specified linear excursion is ±8.8 mm.\u003c\/p\u003e\u003cp\u003eThe water-repellent pressed-paper cone is paired with a high-density flux ferrite motor assembly for low-frequency reproduction in vehicle environments. Basket vents beneath the spider support cooling without a central pole vent. This design also allows the driver to be mounted closer to the rear wall of a properly built enclosure.\u003c\/p\u003e\u003cp\u003eThe APS 8 D is a practical choice for custom OEM-integration upgrades, compact hatchback or trunk installations, and systems using an external subwoofer amplifier. Its dual-coil configuration can be wired for a 2-ohm or 8-ohm final load when both coils are used, provided the amplifier is rated for that load. A steel mesh grille and plastic gasket are included for installation and driver protection.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact Sealed-Box Design:\u003c\/strong\u003e Engineered for sealed enclosures starting at 7.5 liters, helping conserve cargo and installation space.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e79 mm Mounting Depth:\u003c\/strong\u003e The low-profile basket supports installations with limited rear clearance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual 4-Ohm Voice Coils:\u003c\/strong\u003e Enables series or parallel wiring options to suit compatible amplifier load ratings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e250W Continuous Handling:\u003c\/strong\u003e Provides a realistic continuous-power target for selecting an external amplifier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e±8.8 mm Linear Excursion:\u003c\/strong\u003e Supports meaningful cone travel within a shallow-subwoofer installation format.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater-Repellent Paper Cone:\u003c\/strong\u003e Uses a pressed-paper cone material selected for automotive subwoofer duty.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe APS 8 D uses a high-density flux ferrite magnet, water-repellent pressed-paper cone, and a 40 mm voice-coil assembly. Its basket incorporates air vents beneath the spider rather than a central pole vent, and the surround and spider are designed to help control unwanted rocking motion. The included steel mesh grille provides physical protection, while the plastic gasket helps finish the mounting surface.\u003c\/p\u003e\u003cp\u003eInstall the APS 8 D in a sealed enclosure with at least 7.5 liters of internal volume; Audison documents an 8.5-liter, Qtc 0.85 sealed design as a suggested enclosure alignment. Confirm the 187 mm mounting cutout, 79 mm mounting depth, and rear clearance before building or modifying an enclosure. Wire the two 4-ohm voice coils in series for an 8-ohm load or in parallel for a 2-ohm load only when the amplifier is stable at the resulting impedance.\u003c\/p\u003e","brand":"Audison","offers":[{"title":"Default Title","offer_id":45614231748678,"sku":"APS8D","price":249.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/61jRcTTGCbL.jpg?v=1784363091","url":"https:\/\/audiowatt.store\/products\/audison-aps-8-d-prima-8-dual-4-ohm-shallow-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
