The Dayton Audio RST28A-4 aluminum dome Reference Series tweeter offers exceptional efficiency from 1,500 Hz to 20,000 Hz with smooth and well controlled frequency response. This tweeters unique black anodized 1-1\/8\" aluminum diaphragm and state-of-the-art motor system not only match the look and features of Dayton Audios Reference Series woofers and midranges, but also the clean, detailed, and uncolored sound you have come to expect. A specialized damped rear chamber, well-designed phase bridge, rigid mesh grill, and several distortion-reducing paths in the motor are just a few of the features that allow these tweeters to outperform some the most expensive audiophile high-frequency transducers.\u003c\/p\u003e\n\n\u003ch4\u003eFeatures\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/8\" aluminum diaphragm offers remarkable clarity without the typical harshness of metal domes\u003c\/li\u003e\n  \u003cli\u003eExceptional efficiency at 92.5 ±3dB from 1.5 kHz to 19 kHz and a smooth frequency response\u003c\/li\u003e\n  \u003cli\u003eWell-designed phase bridge to balance the response in the upper octave\u003c\/li\u003e\n  \u003cli\u003eTuned rear chamber and high-quality Ferrofluid for excellent low-end response\u003c\/li\u003e\n  \u003cli\u003eLow-distortion motor system achieves a rare level of transparency\u003c\/li\u003e\n  \u003cli\u003eMatches the performance of even the most expensive audiophile high-frequency transducers\u003c\/li\u003e\n  \u003cli\u003eFor applications like line arrays or compact mini-monitors that demand a smaller faceplate\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n  \u003ctr\u003e\n\u003cth\u003eManufacturer\u003c\/th\u003e\n\u003ctd\u003eDayton Audio\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eImpedance\u003c\/th\u003e\n\u003ctd\u003e4Ω Re 3Ω\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eFs\u003c\/th\u003e\n\u003ctd\u003e775Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003ePower\u003c\/th\u003e\n\u003ctd\u003e80Wrms\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eSens.\u003c\/th\u003e\n\u003ctd\u003e92.5dB\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eSize\u003c\/th\u003e\n\u003ctd\u003e1.125'\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eDiam.\u003c\/th\u003e\n\u003ctd\u003e105mmØ\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eHole\u003c\/th\u003e\n\u003ctd\u003e73mmØ\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eQes\u003c\/th\u003e\n\u003ctd\u003e1.65\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eQms\u003c\/th\u003e\n\u003ctd\u003e2.15\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eQts\u003c\/th\u003e\n\u003ctd\u003e0.93\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eType\u003c\/th\u003e\n\u003ctd\u003eTweeter\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eSd\u003c\/th\u003e\n\u003ctd\u003e6.6cm²\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eLe\u003c\/th\u003e\n\u003ctd\u003e0.03mH\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eFrequency\u003c\/th\u003e\n\u003ctd\u003e1500Hz - 20KHz\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eVC\u003c\/th\u003e\n\u003ctd\u003e28.5mmØ\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eColour\u003c\/th\u003e\n\u003ctd\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eSeries\u003c\/th\u003e\n\u003ctd\u003eReference Series\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eRe\u003c\/th\u003e\n\u003ctd\u003e3.0Ω\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Dayton Audio","offers":[{"title":"Default Title","offer_id":53447206273297,"sku":"RST28A-4T","price":98.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0795\/7115\/7265\/files\/RST28A-4T-1_A.png?v=1776901726","url":"https:\/\/nbaudio.com.au\/products\/dayton-audio-reference-dome-tweeter-aluminium-rst28a-4t","provider":"NB Audio","version":"1.0","type":"link"}
