The compact driver delivers clear, balanced audio reproduction suited to background music playback and voice paging applications. Its low-profile white grille sits flush against the ceiling surface for a clean, professional finish. This speaker is intended for residential and light commercial audio installations where a discreet, fixed installation is required. Licensed audio and low-voltage installers are the typical end users, though the straightforward design also supports experienced integrators working on multi-room systems.\u003c\/p\u003e\u003cp\u003eThe ma-420 fits residential rooms, commercial lobbies, retail spaces, and office environments where background music or paging audio is needed. The 8-ohm impedance allows direct wiring to most consumer and light commercial amplifiers without an impedance-matching transformer, simplifying distributed audio runs. Its 4-inch form factor keeps the ceiling cutout small, making it practical for retrofit installations in finished spaces with limited above-ceiling depth.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-inch driver for compact ceiling cutout and smooth audio reproduction\u003c\/li\u003e\n\u003cli\u003e8-ohm impedance for direct amplifier connection without a transformer\u003c\/li\u003e\n\u003cli\u003eWhite grille provides a low-profile, professional appearance\u003c\/li\u003e\n\u003cli\u003eSuited for background music and voice paging in residential and commercial settings\u003c\/li\u003e\n\u003cli\u003eCompact design supports retrofit installs in finished ceilings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 8-ohm in-ceiling speaker compatible with most residential and light commercial amplifiers and distributed audio systems that accept direct 8-ohm speaker loads.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed low-voltage or audio systems technician. Power down the amplifier and any connected audio source equipment before making speaker connections. Follow NEC Article 725 guidelines for low-voltage wiring in finished wall and ceiling assemblies. Do not exceed the amplifier's rated per-channel output when wiring multiple speakers on a single channel without proper impedance calculation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDriver Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImpedance\u003c\/strong\u003e: 8 ohms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrille Color\u003c\/strong\u003e: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Background music, voice paging, multi-room audio\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GENERIC \/ UNBRANDED\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ma-420\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Generic \/ Unbranded","offers":[{"title":"Default Title","offer_id":51525201723698,"sku":"MA-420","price":65.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d939fc533d29b4102735544597bf40a4.jpg?v=1785467047","url":"https:\/\/voomisupply.com\/products\/generic-unbranded-ma-420-ceiling-speaker-4-in-8-ohm","provider":"Voomi Supply","version":"1.0","type":"link"}
