Its single 4-ohm voice coil and 400-watt continuous power rating make it suitable for systems that need controlled low-frequency output without requiring a large enclosure. It is optimized for sealed enclosures beginning at 10 liters, or about 0.35 cubic feet.\u003c\/p\u003e\u003cp\u003eThis subwoofer is intended for installers and enthusiasts working with limited mounting depth in trunks, custom side panels, under-floor spaces, or other compact locations. The 88 mm mounting depth helps make installation possible where conventional full-depth woofers may not fit. Its compact enclosure requirements also support space-conscious system designs.\u003c\/p\u003e\u003cp\u003eThe APS 10 S4S is built to cover bass frequencies with a specified free-air resonance of 28.5 Hz and an excursion capability rated at 12.6 mm Xmax. Its water-repellent pressed-paper cone is engineered to provide a practical balance of low-frequency response and durability for mobile environments. A 60 mm voice coil and high-density flux ferrite motor support power handling and cone control.\u003c\/p\u003e\u003cp\u003eAudison uses a ventilated basket arrangement beneath the spider, eliminating the need for a center-pole vent. This design helps enable installation close to the rear wall of an enclosure while retaining a shallow overall profile. The cone and dust-cap geometry is also designed to support linear movement while keeping mounting depth low.\u003c\/p\u003e\u003cp\u003eAs a passive subwoofer driver, the APS 10 S4S requires a separate compatible amplifier and a properly built enclosure. It can be used as a single 4-ohm subwoofer, or two units can be wired in parallel for a 2-ohm load when matched with an appropriate amplifier. A steel mesh grille and plastic gasket are included to help protect the driver and finish the installation.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e10-Inch Shallow Driver:\u003c\/strong\u003e Fits compact custom subwoofer applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e400W Continuous Power:\u003c\/strong\u003e Supports properly matched external amplification.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle 4-Ohm Voice Coil:\u003c\/strong\u003e Provides straightforward amplifier load matching.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSealed-Enclosure Design:\u003c\/strong\u003e Optimized for enclosures from 10 liters.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater-Repellent Paper Cone:\u003c\/strong\u003e Supports durable mobile-audio use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Density Ferrite Motor:\u003c\/strong\u003e Helps control the cone at excursion.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe APS 10 S4S uses a water-repellent pressed-paper cone, a 60 mm voice coil, and a high-density flux ferrite magnet.

Confirm the available mounting depth of 88 mm and the listed driver dimensions before cutting a mounting opening. Use an amplifier designed to operate safely with a 4-ohm speaker load, observe correct polarity, and ensure the enclosure is rigid and airtight for intended performance.\u003c\/p\u003e","brand":"Hertz","offers":[{"title":"Default Title","offer_id":45631859589190,"sku":"ST35KNEO","price":399.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71Exi-yjeZL_355a8d8c-08c4-4bfe-adf9-e3544bd59a89.jpg?v=1784384229","url":"https:\/\/audiowatt.store\/products\/audison-aps-10-s4s-10-4-ohm-shallow-subwoofer-1","provider":"Audio Watt Store","version":"1.0","type":"link"}
