The ultra-low profile enclosure measures just 142mm (5.6 inches) in depth, making it suitable for boot installations where vertical clearance is limited. The sealed design is precisely tuned to fully exploit the acoustic characteristics of the APS 10 S4S driver, delivering controlled, accurate bass output with the transient response characteristic of a well-matched sealed system.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe enclosure is specifically developed for use with Audison AF bit amplifiers, taking advantage of the bass boost feature and integrated parametric equaliser within the built-in DSP to fine-tune the system's low-frequency response for any vehicle acoustic environment. The 2S2 (2 Sides\/2 Sounds) design supports both Down-Firing and Up-Firing installation orientations, with included levelling feet for Down-Firing use. The SSP (Sub Smart Plug) terminal block provides both Plug-and-Play quick-release connectivity and traditional push contacts for conventional wiring, simplifying installation and impedance configuration. Rounded corners ease positioning in the boot and act as structural reinforcement to reduce enclosure resonance. A sturdy metal grille is included for full driver protection. Handling 400 watts continuous and 800 watts peak at 4 ohms, the APS 10 S4S driver features a cotton-fibre pressed paper cone developed using FEM simulation, a massive motor assembly optimised with Finite Element Modelling, and a water-repellent treated cone surface rated for 11mm one-way linear excursion.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003e\u003cstrong\u003eFeatures \u0026amp; Benefits\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eUltra-Low Profile Sealed Enclosure Tuned for APS 10 S4S:\u003c\/strong\u003e At 142mm (5.6\") depth, the APBX 10 S4S is designed for installations where a standard-depth subwoofer enclosure cannot fit.

Up-Firing installation orients the cone upward toward the cabin, producing more punch and transient definition. The choice depends on the vehicle's acoustic characteristics and the listener's preference. Both orientations are fully supported by the included hardware.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWhy is the APBX 10 S4S specifically matched to AF bit amplifiers?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe APBX 10 S4S is designed as part of the Audison Prima ecosystem, where the driver, enclosure, and amplifier are engineered to work together. The AF bit amplifier's integrated DSP includes a bass boost feature and parametric equaliser that allow the low-frequency response of the APBX 10 S4S to be precisely tuned for any vehicle acoustic environment, compensating for the inherent roll-off characteristics of a compact sealed enclosure and optimising bass output for the installation conditions. While the enclosure can be driven by other amplifiers at 4 ohms and 400W continuous, the full system optimisation is achieved with the matched AF bit amplifier.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWhat does SSP (Sub Smart Plug) mean, and what connection options does it provide?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eSSP stands for Sub Smart Plug.

In the APBX 10 S4S, FEM was used to optimise both the motor assembly for high-excursion control and the cone profile for accurate pistonic motion. The Klippel Scan Vibrometer is a measurement tool used to map the actual vibration behaviour of the cone at multiple points across its surface, confirming that the cone moves as a rigid piston rather than flexing or breaking up, and allowing further refinement of the cone geometry for low-distortion output.\u003c\/p\u003e","brand":"Audison","offers":[{"title":"Default Title","offer_id":43173650137181,"sku":"APBX10S4","price":574.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0640\/9528\/9437\/files\/AP260PP_599x400-3.jpg?v=1742289907","url":"https:\/\/frankiesautoelectrics.com.au\/products\/audison-apbx-10-s4s-10-inch-sealed-subwoofer-enclosure","provider":"Frankies Auto Electrics","version":"1.0","type":"link"}
