Its compact footprint and slim profile make it suitable for installations where space is limited but clean, immersive audio is desired. With a neodymium magnet and a one-inch proprietary voice coil, this transducer is optimized for high sensitivity so it performs well with small Class D amplifiers without demanding large power reserves.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this exciter attach to different surfaces?\u003c\/h3\u003e\n\u003cp\u003eInstallation is straightforward thanks to pre-applied 3M VHB adhesive that bonds quickly and securely to many materials; peel-and-stick mounting simplifies prototyping and permanent installs alike. For applications where extra mechanical security is needed—such as inverted mounting or moving panels—four screw tabs provide a reliable backup. Two PCB-style solder pads keep wiring tidy and compact.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePre-applied 3M™ VHB™ peel-and-stick for immediate bonding\u003c\/li\u003e\n  \u003cli\u003eFour screw tabs for permanent or inverted mounting\u003c\/li\u003e\n  \u003cli\u003eTwo compact solder points for neat electrical connections\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat kind of sound can you expect from a 25mm exciter?\u003c\/h3\u003e\n\u003cp\u003eExciter sound character varies with the material it drives: thinner or smaller surfaces favor brighter mid-high output and higher sensitivity, while thicker or larger panels produce fuller-range, lower-frequency response. The DAEX25FHE-4's high-efficiency motor and cooling vents let it accept more power for greater acoustic output without increasing size. Keep in mind that surface selection and placement, plus the number of exciters used, influence overall tonal balance and loudness.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eThinner panels: louder, mid\/tweeter emphasis\u003c\/li\u003e\n  \u003cli\u003eThicker\/large panels: fuller-range but lower overall level\u003c\/li\u003e\n  \u003cli\u003eMultiple exciters: smoother, more even dispersion and bass performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich amplifiers and power levels are appropriate?\u003c\/h3\u003e\n\u003cp\u003eThe DAEX25FHE-4 is rated 24 watts RMS with a 4-ohm impedance, making it compatible with small Class D amplifiers and compact audio boards. Because the transducer is highly sensitive, you won’t need excessive power to drive useful volume levels; choose an amp that handles 4 ohms and offers headroom for transient peaks. Avoid sustained clipping to protect the voice coil and preserve fidelity.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eNominal impedance: 4 ohms, suitable for compact amps\u003c\/li\u003e\n  \u003cli\u003ePower handling: 24W RMS; use an amp with clean headroom\u003c\/li\u003e\n  \u003cli\u003eHigh sensitivity reduces required amplifier size and power\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat are the physical and technical highlights of the DAEX25FHE-4?\u003c\/h3\u003e\n\u003cp\u003eThis exciter measures just under 2\" (50.5 mm) in diameter and about 7\/8\" (20.5 mm) deep, with adhesive dimensions tailored for strong coupling to the radiating surface. A rare-earth neodymium magnet concentrates magnetic flux for improved efficiency, while a 25 mm voice coil and cooling vents enable higher input power in a slim package. The unit includes a five-year parts and labor warranty in many regions.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eOverall diameter: 50.5 mm; depth: 20.5 mm for tight installations\u003c\/li\u003e\n  \u003cli\u003eNeodymium motor and 25 mm voice coil for high sensitivity\u003c\/li\u003e\n  \u003cli\u003ePre-applied adhesive dimensions: 27.6 mm OD, 21.8 mm ID\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho this is for: The Dayton Audio DAEX25FHE-4 is ideal for designers, hobbyists, and AV integrators who need unobtrusive sound sources for small enclosures, creative audio projects, interactive exhibits, or concealed installations. It’s well suited to anyone converting non-speaker surfaces into sound radiators where space, weight, and appearance matter—especially when paired with compact 4-ohm amplifiers for efficient, high-impact audio.\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 stick the exciter to glass or plastic?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes—3M VHB adhesive bonds to many plastics and glass.
