The drive with N38H neodymium and a FEM-calculated phase plug including horn contour ensure efficient sound conversion. The extremely lightweight aluminum diaphragm and the 25mm CCAR voice coil deliver fast transients and high reliability – ideal for loud front systems and show installations.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Highlights\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eActive 44mm horn tweeter without integrated crossover – for operation with an active crossover.\u003c\/li\u003e\n\u003cli\u003eN38H Neodymium magnet: high field strength in a compact design.\u003c\/li\u003e\n\u003cli\u003eFEM-optimized phase plug and horn for directed radiation and efficiency.\u003c\/li\u003e\n\u003cli\u003eCCAR voice coil (25 mm, Copper Clad Aluminum Ribbon) for high thermal and mechanical load capacity.\u003c\/li\u003e\n\u003cli\u003eUltra-light aluminum diaphragm for high dynamics.\u003c\/li\u003e\n\u003cli\u003eHigh-current screw terminals for secure connection.\u003c\/li\u003e\n\u003cli\u003eHousing impregnation and anti-UV treatment for outdoor use.\u003c\/li\u003e\n\u003cli\u003eRecommended high-pass filtering: from 5 kHz with 12 dB\/Oct. or steeper.\u003c\/li\u003e\n\u003cli\u003eSensitivity: 107 dB – suitable for SPL-oriented setups.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Data\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSize: 44 mm\u003c\/li\u003e\n\u003cli\u003ePower handling (Peak): 100 W\u003c\/li\u003e\n\u003cli\u003eImpedance: 4 Ohm\u003c\/li\u003e\n\u003cli\u003eVoice coil: Ø 25 mm\u003c\/li\u003e\n\u003cli\u003eFrequency response: 3 kHz – 20 kHz\u003c\/li\u003e\n\u003cli\u003eWeight: 0.39 kg\u003c\/li\u003e\n\u003cli\u003eMagnet: Neodymium\u003c\/li\u003e\n\u003cli\u003eDiaphragm: Aluminum\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eElectro-acoustic Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEffective diaphragm diameter (D): 35.5 mm\u003c\/li\u003e\n\u003cli\u003eDC resistance (Re): 2.9 Ohm\u003c\/li\u003e\n\u003cli\u003eResonance frequency (Fs): 3,900 Hz\u003c\/li\u003e\n\u003cli\u003eInductance (Le): 0.03 mH\u003c\/li\u003e\n\u003cli\u003eForce factor (Bl): 2.05 T·m\u003c\/li\u003e\n\u003cli\u003eSensitivity (SPL): 107 dB\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eDimensions\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eA: 57 mm\u003c\/li\u003e\n\u003cli\u003eB: 43.5 mm\u003c\/li\u003e\n\u003cli\u003eC: 55.5 mm\u003c\/li\u003e\n\u003cli\u003eD: 29.7 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eInstallation \u0026amp; Compatibility\u003c\/h3\u003e\n\u003cp\u003eInstall the ST 25A Neo.2 in A-pillar pods, mirror triangles, or custom mounts. Its compact depth facilitates installation in tight spaces. Designed purely as a tweeter, it requires active crossover – plan for a high-pass crossover from 5 kHz with 12 dB\/octave (or steeper). In combination with powerful mid-range\/mid-bass drivers, it creates a strong front system with high vocal and detail clarity – especially where sound pressure and precision are required.\u003c\/p\u003e","brand":"Hertz","offers":[{"title":"Default Title","offer_id":52841089007952,"sku":"ST-25A-NEO.2","price":169.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0933\/3004\/7312\/files\/hertz-spl-show-st-25a-neo_2-horn-hochtoner-carhifi_shop-kaufen.webp?v=1774448665","url":"https:\/\/carhifi.shop\/en\/products\/hertz-spl-show-st-25a-neo-2-horn-hochtoener","provider":"Carhifi Shop","version":"1.0","type":"link"}
