The SF 228T Plus pairs a coaxial 8 in polypropylene woofer with a 1.1 in silk dome tweeter around a 2.5 kHz crossover, ships with cross bars sized for a 2x2 tile opening, and carries a UL 2043 plenum rating so it can sit directly in return-air ceilings. A full-range power limiter on the crossover guards the drivers if an amplifier is pushed past its rated output.\u003c\/p\u003e\n\u003ch3\u003eKey Capabilities\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e47 Hz to 22 kHz frequency range (-10 dB, half space); response holds within ±3 dB from 63 Hz to 12.5 kHz.\u003c\/li\u003e\n\u003cli\u003e90 W rms continuous pink noise, 180 W rms continuous program per pair.\u003c\/li\u003e\n\u003cli\u003eSelectable 70 V taps (64\/32\/16\/8 W) or 100 V taps (64\/32\/16 W), plus direct 8 ohm operation.\u003c\/li\u003e\n\u003cli\u003e95° conical coverage with 89 dB sensitivity at 1 W \/ 1 m.\u003c\/li\u003e\n\u003cli\u003eUL 2043 and UL 1480A listed composite enclosure for plenum airspace.\u003c\/li\u003e\n\u003cli\u003eMaximum SPL of 104.9 dB at 1 m based on rated maximum input voltage.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhere It Is Used\u003c\/h3\u003e\n\u003cp\u003eConference rooms, training rooms, open-plan offices and retail spaces that already run 70V\/100V distributed audio and need a shallow, plenum-rated tile speaker sitting flush beside ceiling-mounted displays.\u003c\/p\u003e\n\u003ch3\u003eSpecifications at a Glance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEnclosure: 5.41 in H x 23.75 in W x 23.75 in L, 18.9 lbs each\u003c\/li\u003e\n\u003cli\u003eDrivers: 8 in polypropylene woofer, 1.1 in silk dome tweeter, 2.5 kHz crossover\u003c\/li\u003e\n\u003cli\u003eInputs: (2) 3-pole splicing connectors, 1 input plus loop-through\u003c\/li\u003e\n\u003cli\u003eNominal impedance: 8 ohms per speaker\u003c\/li\u003e\n\u003cli\u003eWarranty: 5 years parts and labor\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"alt-refs\"\u003eAlso referenced as Extron SF228TPlus, SF-228T-Plus, part number 60186203.\u003c\/p\u003e","brand":"Extron","offers":[{"title":"Default Title","offer_id":52302929166556,"sku":"EXTRON-SF228TPLUS-60186203","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0754\/5582\/4092\/files\/extron-sf-228t-plus-60-1862-03.png?v=1787224612","url":"https:\/\/www.ampronix.com\/products\/extron-sf-228t-plus-60-1862-03","provider":"Ampronix","version":"1.0","type":"link"}
