Its tiny footprint—just over an inch in diameter and about 3\/8\" high—lets designers embed audio into toys, cabinets, instrument panels, displays, and more. The DAEX13CT-4 offers a 4 Ω nominal impedance for easy matching with small Class D amplifiers and includes two PCB solder points for tidy, compact wiring.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this exciter turn objects into speakers?\u003c\/h3\u003e\n\u003cp\u003eThe DAEX13CT-4 converts electrical audio signal into mechanical vibration via a proprietary voice coil and rare-earth neodymium magnet. When attached to a surface, those vibrations transfer into the material and create audible sound, effectively turning the panel or object itself into a radiating diaphragm.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e13 mm voice coil optimized for small surfaces\u003c\/li\u003e\n  \u003cli\u003eNeodymium magnet for high magnetic flux and sensitivity\u003c\/li\u003e\n  \u003cli\u003ePre-applied 3M VHB adhesive for reliable energy transfer\u003c\/li\u003e\n  \u003cli\u003eTwo PCB solder points for neat connections\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat performance should I expect from this 3W, 4-ohm exciter?\u003c\/h3\u003e\n\u003cp\u003eThis exciter is designed for low-power applications; its neodymium motor improves sensitivity so modest amplifiers can drive it effectively. Output and frequency balance depend heavily on the surface size and material: thin, small panels emphasize mid and high frequencies, while larger, stiffer panels give fuller-range output when used in arrays.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e3 W nominal handling for compact amplifier systems\u003c\/li\u003e\n  \u003cli\u003e4 Ω impedance enables series and parallel arrays for tailored dispersion\u003c\/li\u003e\n  \u003cli\u003eSurface-dependent frequency response—experiment for best results\u003c\/li\u003e\n  \u003cli\u003eIdeal for adding localized audio without visible speakers\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow do I install the DAEX13CT-4 and what mounting options work best?\u003c\/h3\u003e\n\u003cp\u003eInstallation is straightforward: peel the pre-applied 3M VHB backing and stick the exciter to a clean, flat spot on the chosen surface. For reliable adhesion and maximum acoustic transfer, choose an area free of heavy curvature, oily residues, or loose finishes.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePeel-and-stick 3M VHB adhesive with 15.7 mm outside diameter\u003c\/li\u003e\n  \u003cli\u003eSolder to the two PCB pads or use thin gauge wires for compact runs\u003c\/li\u003e\n  \u003cli\u003eTest placement—loudness and tone change with location and surface type\u003c\/li\u003e\n  \u003cli\u003eUse multiple exciters in series\/parallel for larger or thicker panels\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan I use this in arrays or with other audio components?\u003c\/h3\u003e\n\u003cp\u003eYes—because the exciter has a 4 Ω nominal impedance, you can wire several units in series or series-parallel to match amplifier loads and shape dispersion. Small Class D amps pair well for battery-powered or embedded projects where footprint and efficiency matter.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eSeries wiring raises total impedance for compact amp compatibility\u003c\/li\u003e\n  \u003cli\u003eSeries-parallel configs let you scale loudness and coverage\u003c\/li\u003e\n  \u003cli\u003eWorks well with small Class D amplifiers for efficient power use\u003c\/li\u003e\n  \u003cli\u003eMultiple exciters smooth frequency response across larger surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for? Engineers, product designers, hobbyists, and educators who need invisible or space-constrained audio solutions will benefit most from the DAEX13CT-4. It’s ideal for toy designers, exhibit builders, cabinet and furniture audio integration, hobby electronics, and any project that needs localized sound without visible speaker cones. Experimenting with different materials and array configurations will yield the best match of tone and volume for your application.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What amplifier do I need for the DAEX13CT-4?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: A small Class D amplifier that can drive 4 Ω loads at around 3 W per exciter is ideal.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will it damage surfaces when removed?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: The 3M VHB adhesive bonds strongly; careful removal may leave residue or require heat and adhesive remover.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Dayton Audio","offers":[{"title":"Default Title","offer_id":48412920316061,"sku":"B00M291ZSI","price":20.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0766\/9596\/1757\/files\/dayton-audio-daex13ct-4-front-view.jpg?v=1781253070","url":"https:\/\/nexoltic.com\/products\/dayton-audio-13mm-coin-exciter-4%cf%89-3w-daex13ct-4","provider":"Nexoltic","version":"1.0","type":"link"}
