This type of speaker is a standard component in commercial and light commercial paging, background music, and life-safety audio systems. The back box enclosure improves acoustic performance by isolating the driver from open plenum space and provides a defined air volume for more consistent low-frequency output. Audio technicians and low-voltage installation contractors are the primary trades who specify and install this unit.\u003c\/p\u003e\n\u003cp\u003eThe SP5MATB is suited for drop-ceiling and drywall-ceiling installations in commercial environments such as offices, retail spaces, restaurants, schools, and healthcare facilities. The 25\/70-volt design allows multiple speakers to be wired in parallel on a single amplifier circuit without complex impedance matching, which is the standard approach for distributed audio in commercial builds. The included back box makes this unit appropriate for plenum-rated ceiling spaces where an open-back speaker would not be acceptable or would perform poorly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5.25-inch driver in a self-contained assembly with integrated back box\u003c\/li\u003e\n  \u003cli\u003e25-volt and 70-volt transformer compatibility for distributed audio systems\u003c\/li\u003e\n  \u003cli\u003eBack box enclosure improves acoustic isolation and low-frequency response in open plenum installations\u003c\/li\u003e\n  \u003cli\u003eIn-ceiling form factor suits flush-mount commercial applications\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit (each)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation component for 25-volt and 70-volt distributed audio systems commonly found in commercial in-ceiling speaker applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed low-voltage contractor or qualified audio systems technician in accordance with applicable local codes and NEC Article 725 for low-voltage wiring. De-energize the amplifier and disconnect the speaker circuit before making any wiring connections. The back box must be secured properly to the ceiling structure to prevent movement and ensure a consistent seal. Verify transformer tap settings match the amplifier output voltage before powering the system.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDriver Size\u003c\/strong\u003e: 5.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem Voltage\u003c\/strong\u003e: 25 volts \/ 70 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnclosure Type\u003c\/strong\u003e: Integrated back box\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Location\u003c\/strong\u003e: In-ceiling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity Per\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SPECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SP5MATB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPECO","offers":[{"title":"Default Title","offer_id":51687842677042,"sku":"SP5MATB","price":228.93,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/speco-sp5matb-in-ceiling-speaker-5-25-in-25-70v","provider":"Voomi Supply","version":"1.0","type":"link"}
