It combines a woofer and tweeter into each speaker assembly, helping simplify installation where a factory 4x6-inch opening is available. This format is suited to drivers seeking an updated speaker solution without adding separate external crossovers.\u003c\/p\u003e\u003cp\u003eRated at 90 watts RMS and 180 watts peak per pair, the XK2-146 is intended for systems that need more power capability than a basic factory speaker replacement. Its 88 dB sensitivity and stated 55 Hz to 22 kHz frequency response describe a design made to cover a broad portion of the audible range. Match the speakers with an appropriately rated source unit or amplifier and avoid exceeding their continuous power rating.\u003c\/p\u003e\u003cp\u003eThe 2-way coaxial layout places high-frequency reproduction within the same speaker assembly as the main driver. This can be useful in factory-style locations where there is limited space for separate tweeters. The result is a straightforward speaker upgrade path for compatible dash, door, or rear-deck locations.\u003c\/p\u003e\u003cp\u003eThe XK2-146 uses a compact 4x6-inch footprint for vehicles designed around that common speaker size. Confirmed mounting guidance lists a 5.5 x 3.46-inch cutout requirement and a 3-inch depth from the flange. Measuring the original opening, mounting-hole pattern, and clearance behind the panel remains important before purchase.\u003c\/p\u003e\u003cp\u003eThese speakers can be used as a direct replacement pair or as part of a larger system with an aftermarket receiver or external amplification. They are most appropriate when the installation location accepts their stated dimensions and the system can be configured for their power range. Vehicle-specific adapters, harnesses, and mounting hardware may be needed depending on the application.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e4x6-Inch Speaker Size:\u003c\/strong\u003e Fits applications designed for compact 4x6-inch speakers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2-Way Coaxial Design:\u003c\/strong\u003e Integrates woofer and tweeter functions in each speaker.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e90W RMS Per Pair:\u003c\/strong\u003e Supports systems with appropriately matched continuous power.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e180W Peak Per Pair:\u003c\/strong\u003e Provides stated short-term peak power handling.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e55 Hz–22 kHz Response:\u003c\/strong\u003e Covers bass, midrange, and high-frequency content.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e88 dB Sensitivity:\u003c\/strong\u003e Indicates the stated efficiency rating for the pair.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe XK2-146 is a compact coaxial speaker system built for automotive use. Confirmed listing information describes durable, high-quality construction, but does not identify specific cone, surround, tweeter, basket, magnet, or voice-coil materials. Its integrated 2-way layout keeps the installation format simple for locations that do not accommodate separate component speakers.\u003c\/p\u003e\u003cp\u003eBefore installation, verify that the vehicle has a compatible 4x6-inch speaker location, a 5.5 x 3.46-inch cutout, and at least 3 inches of clearance from the mounting flange. Check mounting-hole alignment and connector compatibility, since adapters or a vehicle-specific wiring harness may be required. For amplified systems, set gain conservatively and match power delivery to the 90-watt RMS-per-pair rating.\u003c\/p\u003e","brand":"MB Quart","offers":[{"title":"Default Title","offer_id":45633165787206,"sku":"XK2-146","price":38.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/616fLwwkaXL.jpg?v=1784408008","url":"https:\/\/audiowatt.store\/products\/mb-quart-xk2-146-4x6-2-way-coaxial-speakers","provider":"Audio Watt Store","version":"1.0","type":"link"}
