{"product_id":"audison-aps-8-r-8-4-ohm-subwoofer","title":"Audison APS 8 R 8\" 4 Ohm Subwoofer","description":"\u003cp\u003eThe Audison APS 8 R is an 8-inch, 4-ohm subwoofer driver designed for vehicle audio systems where available enclosure depth is limited. It provides a 250-watt continuous power rating and is intended to add controlled low-frequency output without requiring a large driver. Its compact installation profile makes it a practical option for custom trunk, side-panel, or space-conscious enclosure projects.\u003c\/p\u003e\u003cp\u003eThis subwoofer is designed for a reflex, or ported, enclosure with a minimum internal volume of 8.5 liters. Audison specifies a recommended tuning range between 30 and 40 Hz for this application. That design focus makes the APS 8 R suitable for systems seeking bass extension from a compact ported enclosure.\u003c\/p\u003e\u003cp\u003eThe APS 8 R uses a water-repellent pressed-paper cone and a 40 mm voice coil. Its 8.8 mm Xmax supports substantial linear cone travel for its shallow form factor. The 84 dB sensitivity and 4-ohm impedance should be considered when selecting a compatible amplifier and system tuning.\u003c\/p\u003e\u003cp\u003eAudison uses a cone, dustcap, and basket geometry intended to preserve excursion while keeping mounting depth low. Basket vents located beneath the spider provide cooling without a central pole vent. This layout allows the driver to be mounted closer to the rear wall of an enclosure than designs requiring rear pole ventilation.\u003c\/p\u003e\u003cp\u003eThe APS 8 R fits naturally into an Audison Prima-based upgrade or a custom compact subwoofer system. It can be paired with an appropriately configured external amplifier and a properly designed ported enclosure. A steel mesh grille and plastic gasket are included to support installation and driver protection.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e8-Inch Subwoofer Driver:\u003c\/strong\u003e Adds bass capability in a compact speaker format.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e250W Continuous Power:\u003c\/strong\u003e Supports amplifier matching for sustained playback.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4-Ohm Impedance:\u003c\/strong\u003e Works with compatible 4-ohm amplifier channels.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShallow 79 mm Mounting Depth:\u003c\/strong\u003e Helps fit restricted installation locations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorted-Enclosure Design:\u003c\/strong\u003e Optimized for reflex enclosures from 8.5 liters.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBasket Venting:\u003c\/strong\u003e Supports cooling while allowing close rear-wall mounting.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe APS 8 R combines a water-repellent pressed-paper cone with a high-density flux ferrite motor assembly. Its motor is optimized using finite element modeling, while the surround and spider are designed to help control rocking-mode behavior. The supplied steel mesh grille and plastic gasket complement the driver for a finished installation.\u003c\/p\u003e\u003cp\u003eUse this subwoofer in a properly built reflex enclosure with at least 8.5 liters of internal volume and a 30-40 Hz tuning target. Confirm the 187 mm installation opening and 79 mm mounting depth against the available mounting location before cutting. Select an external amplifier compatible with a 4-ohm load, then set crossover, gain, and enclosure tuning carefully for the system.\u003c\/p\u003e","brand":"Audison","offers":[{"title":"Default Title","offer_id":45614232109126,"sku":"APS8R","price":249.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71fVrbU7MCL.jpg?v=1784363133","url":"https:\/\/audiowatt.store\/products\/audison-aps-8-r-8-4-ohm-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
