Built around a neodymium motor and proprietary voice coil, the DAEX25CT-4 offers higher sensitivity than many similarly sized exciters and uses a 4 Ω load compatible with small Class D amps. The pre-applied 3M VHB adhesive makes attachment fast and durable, so you can prototype or install permanent audio solutions without drilling or extra hardware.\u003c\/p\u003e\n\n\u003ch3\u003eHow loud and powerful is this tiny transducer?\u003c\/h3\u003e\n\n\u003cp\u003eDespite its compact footprint, the DAEX25CT-4 supports 10 W RMS input thanks to a full-inch voice coil that accepts more power than typical coin exciters. Loudness will vary with the chosen mounting surface, but the neodymium motor and efficient coil design help maximize acoustic output while keeping power needs modest.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e10 W RMS power handling through a 1\" voice coil for higher output\u003c\/li\u003e\n  \u003cli\u003eNeodymium magnet improves sensitivity and lowers amplifier demand\u003c\/li\u003e\n  \u003cli\u003e4 Ω impedance suitable for many small Class D amplifiers\u003c\/li\u003e\n  \u003cli\u003eSurface-dependent SPL — thin\/smaller panels trend brighter, thicker\/larger panels yield fuller sound\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat surfaces work best with the DAEX25CT-4 and how does mounting affect sound?\u003c\/h3\u003e\n\n\u003cp\u003eThis exciter turns rigid materials into radiating surfaces; characteristics of the surface determine frequency balance and loudness. Thinner, lighter panels emphasize mid and high frequencies and often sound louder, while thicker, larger panels reproduce fuller low frequencies but may need multiple exciters to reach similar SPLs.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eIdeal for plastics, woods, glass, and thin metal panels\u003c\/li\u003e\n  \u003cli\u003eSmaller\/thinner panels = brighter, mid\/tweeter character\u003c\/li\u003e\n  \u003cli\u003eLarger\/thicker panels = fuller range, may require multiple exciters\u003c\/li\u003e\n  \u003cli\u003ePre-applied 3M VHB adhesive ensures efficient energy transfer to surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow easy is installation and wiring for prototypes or final builds?\u003c\/h3\u003e\n\n\u003cp\u003eInstallation is designed to be quick and compact: peel the pre-applied 3M VHB backing and press the exciter to the chosen surface for a strong bond. Two PCB solder pads keep wiring neat; because of the high sensitivity, you can often use very small amplifiers for powering the unit.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003ePre-applied 3M™ VHB™ adhesive — peel-and-stick mounting\u003c\/li\u003e\n  \u003cli\u003eTwo PCB solder points for tidy, low-profile connections\u003c\/li\u003e\n  \u003cli\u003eCompact dimensions (≈48 mm diameter, 15 mm depth) fit tight spaces\u003c\/li\u003e\n  \u003cli\u003eWorks with small Class D amps at 4 Ω for simple system design\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat technical specs and design details should I know before buying?\u003c\/h3\u003e\n\n\u003cp\u003eThe DAEX25CT-4 is engineered around a 25 mm (1\") voice coil and neodymium magnet to balance power handling and compact size. While its resonant frequency and frequency response depend on the mount, the transducer's mechanical design allows efficient coupling and robust performance in many lightweight audio applications.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eVoice coil diameter: 25 mm (1\") for 10 W RMS handling\u003c\/li\u003e\n  \u003cli\u003eImpedance: 4 Ω, DC resistance ~3.6 Ω\u003c\/li\u003e\n  \u003cli\u003eOverall diameter ≈48 mm, depth ≈15 mm; adhesive outer diameter 27 mm\u003c\/li\u003e\n  \u003cli\u003ePre-applied adhesive and solder pads for quick installs; 5-year parts and labor warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for? The Dayton Audio DAEX25CT-4 is aimed at designers, makers, and integrators who need a discreet, high-sensitivity exciter for compact enclosures, interactive exhibits, toys, displays, or furniture-based audio. Choose this model if you want a peel-and-stick installation, higher-than-average power handling for its size, and compatibility with small 4 Ω amplifier modules. For larger installations or deeper bass, pair multiple exciters or select thicker panel materials to achieve the desired frequency balance.\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: Can I use the DAEX25CT-4 on glass or metal?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — it bonds to rigid surfaces like glass and metal; sound character changes with material thickness.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What amplifier do I need for this 4 Ω exciter?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: A small Class D amplifier rated for 4 Ω and up to 10 W RMS per channel will drive it effectively.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Dayton Audio","offers":[{"title":"Default Title","offer_id":48412920250525,"sku":"B00M292316","price":18.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0766\/9596\/1757\/files\/dayton-audio-daex25ct-4-front-view.jpg?v=1781253071","url":"https:\/\/nexoltic.com\/products\/dayton-audio-25mm-coin-exciter-daex25ct-4-10w-4%cf%89","provider":"Nexoltic","version":"1.0","type":"link"}
