It is intended for listeners who want more bass presence than factory speakers or full-range aftermarket speakers can provide on their own. Because it is a passive subwoofer, it requires a separate compatible external amplifier and enclosure.\u003c\/p\u003e\u003cp\u003eWith 400 watts RMS power handling and 1,400 watts maximum power handling, the TS-A30S4 is suited to systems built around a properly matched mono or bridged amplifier. Its single 4-ohm voice coil provides a straightforward load for compatible amplification. The 87 dB sensitivity rating and 22 Hz to 1.6 kHz frequency range support use as a dedicated bass driver.\u003c\/p\u003e\u003cp\u003eThe woofer uses Pioneer’s glass-fiber and mica-reinforced injection-molded polypropylene cone. This rigid composite cone is paired with an elastic polymer\/butyl-rubber surround and a polycotton spider assembly. Together, these components are designed to support controlled cone movement during bass playback.\u003c\/p\u003e\u003cp\u003eThe TS-A30S4 is part of Pioneer’s A-Series range and can be paired with A-Series full-range speakers as part of a coordinated vehicle upgrade. It provides the low-end foundation while the main speakers handle midrange and high-frequency detail. An amplifier with appropriate crossover settings helps direct bass frequencies to the subwoofer.\u003c\/p\u003e\u003cp\u003eInstallation flexibility comes from support for sealed or vented enclosures. Pioneer specifies a 1.25 cubic foot sealed enclosure or a 1.5 cubic foot vented enclosure, allowing the system to be tailored for available space and enclosure preference. Confirm cutout, mounting depth, enclosure volume, and amplifier compatibility before installation.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e12-Inch Component Subwoofer:\u003c\/strong\u003e Adds dedicated bass output to a custom car audio system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e400W RMS Handling:\u003c\/strong\u003e Supports amplifier matching around its continuous power rating.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle 4-Ohm Voice Coil:\u003c\/strong\u003e Provides straightforward wiring with compatible external amplifiers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIMPP Composite Cone:\u003c\/strong\u003e Uses glass-fiber and mica-reinforced polypropylene construction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e22 Hz–1.6 kHz Range:\u003c\/strong\u003e Covers low bass through upper bass frequencies.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSealed Or Vented Compatibility:\u003c\/strong\u003e Supports manufacturer-specified enclosure options for system planning.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe TS-A30S4 combines a glass-fiber and mica-reinforced IMPP cone with a ferrite magnet, elastic polymer\/butyl-rubber surround, and polycotton spider. Its single voice coil uses an aluminum bobbin, while push terminals provide the speaker-wire connection. The driver has a 318 mm outside diameter and a 281 mm cutout requirement.\u003c\/p\u003e\u003cp\u003ePlan for a 136 mm mounting depth behind the mounting surface and use the supplied gasket when installing the driver. A sealed enclosure of 35.4 L (1.25 cu. ft.) or a vented enclosure of 42.5 L (1.5 cu. ft.) is recommended. Use an external amplifier compatible with a 4-ohm load, set gain carefully, and apply a suitable low-pass crossover for subwoofer duty.\u003c\/p\u003e","brand":"Pioneer","offers":[{"title":"Default Title","offer_id":45633229062214,"sku":"TS-A30S4","price":106.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71q4-gjlLbL.jpg?v=1784419074","url":"https:\/\/audiowatt.store\/products\/pioneer-ts-a30s4-12-component-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
