The enclosure is constructed from wood and supports both vertical and horizontal mounting orientations. Wiring can be run concealed inside the wall or exposed, depending on the installation requirement. The unit houses two built-in 6-inch double-cone speaker drivers and incorporates a tap-adjustable transformer that allows operation on 70-volt or 100-volt distributed audio systems with selectable power levels. A push-in input connector speeds up cable termination and supports bridge wiring configurations. Licensed audio or low-voltage technicians typically handle installation in these environments.\u003c\/p\u003e\n\u003cp\u003eThe bs-678 is suited for indoor applications where a compact, unobtrusive wall-mount speaker is needed in a distributed audio system. Typical deployment environments include retail spaces, classrooms, corridors, offices, and institutional facilities. The combination of wood enclosure aesthetics and transformer flexibility makes it appropriate wherever a 70-volt or 100-volt system is already in place. The mounting structure is designed to maintain a secure connection to the wall surface even when outward force is applied, reducing the risk of the cabinet pulling free under load.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWood enclosure cabinet for aesthetically neutral wall integration\u003c\/li\u003e\n  \u003cli\u003eTwo built-in 6-inch double-cone speaker units for full-range sound reproduction\u003c\/li\u003e\n  \u003cli\u003eTap-adjustable transformer supports 70-volt and 100-volt distributed audio systems\u003c\/li\u003e\n  \u003cli\u003eSelectable power tap levels for flexible system design\u003c\/li\u003e\n  \u003cli\u003ePush-in input connector for fast cable connection and bridge wiring\u003c\/li\u003e\n  \u003cli\u003eMounts vertically or horizontally with concealed or exposed wiring options\u003c\/li\u003e\n  \u003cli\u003eMounting structure resists outward force for secure long-term wall attachment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-install wall-mount speaker for 70-volt and 100-volt distributed audio systems in commercial, educational, retail, and institutional environments.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed low-voltage or audio systems technician. De-energize the amplifier and distribution system before making any wiring connections. Select the appropriate transformer tap for the desired power draw before finalizing the installation to ensure the total system load stays within amplifier ratings. Verify local electrical and building codes for requirements governing speaker placement, wiring methods, and plenum-rated cable where applicable.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpeaker Driver Configuration\u003c\/strong\u003e: Two 6-inch double-cone units\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower\u003c\/strong\u003e: 3W\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem Voltage\u003c\/strong\u003e: 70V \/ 100V distributed audio\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTransformer\u003c\/strong\u003e: Tap-adjustable, selectable power levels\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Orientation\u003c\/strong\u003e: Vertical or horizontal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWiring Method\u003c\/strong\u003e: Concealed in-wall or exposed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInput Connector\u003c\/strong\u003e: Push-in type, bridge wiring supported\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnclosure Material\u003c\/strong\u003e: Wood\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: TOA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: bs-678\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TOA","offers":[{"title":"Default Title","offer_id":51525378769202,"sku":"BS-678","price":78.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/145d16fffedd56fc95b65e2400a6a1b5.jpg?v=1785472204","url":"https:\/\/voomisupply.com\/products\/toa-bs-678-wall-mount-speaker-70v-100v-3w-wood","provider":"Voomi Supply","version":"1.0","type":"link"}
