{"product_id":"audison-ap-4-4-midrange-speakers","title":"Audison AP 4 4\" Midrange Speakers","description":"\u003cp\u003eThe Audison AP 4 is a pair of 4-inch car-audio midbass\/midrange drivers designed for factory-location upgrades where space is limited. Their compact format and shallow installation profile help address fitment challenges in many OEM speaker positions. They are intended for listeners building a more detailed front stage or replacing small factory drivers.\u003c\/p\u003e\u003cp\u003eWith a 4-ohm nominal impedance, 40-watt continuous power handling, and 91 dB sensitivity, the AP 4 is suited to compatible factory-power and amplified systems. Its 80 Hz to 7.5 kHz frequency response covers a broad midbass and midrange range for a driver of this size. The sound-oriented design focuses on clear, balanced reproduction through the vocal and upper-midrange region.\u003c\/p\u003e\u003cp\u003eA 25 mm pure-copper voice coil supports controlled performance through the mid-high frequencies. The cone is engineered to provide a calibrated mechanical low-pass behavior, so Audison states that a passive crossover is not required to maximize driver efficiency. This makes the AP 4 a practical option for system designs that need a dedicated small-format midrange or midbass driver.\u003c\/p\u003e\u003cp\u003eThe water-repellent treated paper cone uses a profile developed with FEM simulation and optimized with Klippel Scan Vibrometer measurement. Its shallow Triple Wave TPU surround is designed to support linear excursion. Together, these elements support a compact driver intended for accurate output in OEM-style mounting locations.\u003c\/p\u003e\u003cp\u003eThe AP 4 can be used as part of a component-based car-audio upgrade with appropriate system tuning and amplification. It is supplied as a pair, allowing installation across left and right speaker locations. Confirm the vehicle's opening diameter, mounting depth, wiring polarity, and available signal range before installation.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e4-Inch Driver Size:\u003c\/strong\u003e Fits applications designed for 100 mm speakers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e40W Continuous Handling:\u003c\/strong\u003e Supports power-matched factory or amplified systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e25 mm Copper Voice Coil:\u003c\/strong\u003e Helps maintain balanced mid-high-frequency reproduction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater-Repellent Paper Cone:\u003c\/strong\u003e Uses a treated paper cone construction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTriple Wave TPU Surround:\u003c\/strong\u003e Supports linear cone excursion in a shallow profile.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMechanical Low-Pass Behavior:\u003c\/strong\u003e Reduces the need for a passive crossover.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe AP 4 uses a water-repellent treated paper cone, a 25 mm pure-copper voice coil, and a thermoplastic polyurethane surround with Audison's shallow Triple Wave profile. Its compact basket has an abrasion-resistant, scratch-resistant coating. The driver has a nominal 100 mm diameter, a 103 mm outer diameter, and a 0.4 kg listed weight.\u003c\/p\u003e\u003cp\u003eCheck for a 93 mm installation opening and approximately 41 mm of mounting-depth clearance before purchase; the manufacturer also lists a 43 mm overall depth dimension. Use the pair in matching left\/right locations with a compatible 4-ohm signal path and power source. APG 4 protective grilles are listed by Audison as an optional accessory rather than a confirmed included item.\u003c\/p\u003e","brand":"Audison","offers":[{"title":"Default Title","offer_id":45614217625670,"sku":"AP4","price":249.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71nDD8nYniL.jpg?v=1784361841","url":"https:\/\/audiowatt.store\/products\/audison-ap-4-4-midrange-speakers","provider":"Audio Watt Store","version":"1.0","type":"link"}
