{"product_id":"12-inch-dual-voice-coil-subwoofer-2","title":"12-Inch Dual Voice Coil Subwoofer","description":"The Pioneer TS-A300D4 is a 12-inch A-Series subwoofer engineered to provide drivers with dynamic, high-impact bass for an immersive audio experience. Its construction includes a highly rigid IMPP composite cone, reinforced with glass fiber and mica for enhanced rigidity, reduced distortion, and improved transient response. The cone's design also offers better damping properties, minimizes unwanted vibrations, and ensures thermal stability during high-power use, resulting in cleaner sound and improved reliability.\n\nThe subwoofer's motor structure is built around a large 60oz double-stacked magnet with a vented backplate, which facilitates a better low-frequency response and increases motor force. This allows the speaker to move the cone with greater precision and authority, leading to improved bass reproduction, deeper extension, and increased overall output capability. The double-stacked magnet configuration boosts the magnetic flux, providing superior force and control over the voice coil for improved linearity, cone control, and efficiency.\n\nFurther enhancing its performance is a 4-layer copper voice coil. This configuration improves power handling, thermal management, and magnetic field strength compared to dual-layer designs. Copper's high electrical conductivity minimizes resistive losses and ensures more efficient power transfer, contributing to improved power handling capabilities and overall system efficiency. The TS-A300D4 boasts a maximum music power of 1500W and an RMS power of 500W, with a frequency response ranging from 20 Hz to 2,300 Hz.","brand":"Pioneer","offers":[{"title":"Default Title","offer_id":52664224809272,"sku":"TS-A300D4","price":330.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687547537.jpg?v=1784335466","url":"https:\/\/store.motormia.co\/products\/12-inch-dual-voice-coil-subwoofer-2","provider":"MOTORMIA","version":"1.0","type":"link"}
