Overall external dimensions are 278 x 278 x 161mm. Pair with a robust multi-channel AV amplifier or a high-power streaming amp capable of delivering up to 225W to make the most of this speaker's dynamic range; a Sonos Amp or similar may be underpowered for this model's full potential.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Format\u003c\/td\u003e\n\u003ctd\u003e3-Way\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency Response (-6dB)\u003c\/td\u003e\n\u003ctd\u003e45 Hz - 35 kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal Impedance\u003c\/td\u003e\n\u003ctd\u003e6 ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum Impedance\u003c\/td\u003e\n\u003ctd\u003e4.8 ohm @ 2 kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensitivity\u003c\/td\u003e\n\u003ctd\u003e89 dB (2.83Vrms @ 1m)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Peak SPL\u003c\/td\u003e\n\u003ctd\u003e119 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eContinuous Power Handling\u003c\/td\u003e\n\u003ctd\u003e150W RMS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommended Amplifier Power\u003c\/td\u003e\n\u003ctd\u003e60-225W RMS into 8 ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDrive Units\u003c\/td\u003e\n\u003ctd\u003e1x 9\" RDT III bass, 1x 4\" IDC II midrange, 1x 1\" IDC II tweeter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting Depth\u003c\/td\u003e\n\u003ctd\u003e157mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCut-Out\u003c\/td\u003e\n\u003ctd\u003e248mm square\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExternal Dimensions\u003c\/td\u003e\n\u003ctd\u003e278 x 278 x 161mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e5kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Monitor Audio","offers":[{"title":"Single","offer_id":55348762804563,"sku":"C3L","price":749.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1115\/1323\/9891\/files\/p_C3L-MAIN_ba96cc28-178f-4440-886b-32a8ef83eed0.jpg?v=1791895621","url":"https:\/\/www.ceiling-speakers.co\/products\/monitor-audio-c3l-9-inch-in-ceiling-speaker","provider":"Ceiling Speaker Warehouse","version":"1.0","type":"link"}
