{"product_id":"monitor-audio-iv140-invisible-in-wall-speaker","title":"Monitor Audio IV140 Invisible In-Wall Speaker","description":"\u003cp\u003eThe Monitor Audio IV140 is an invisible in-wall and in-ceiling speaker designed to be fully plastered over, leaving no visible grille or speaker face once finished. It is suited to rooms where a completely seamless, unobtrusive wall or ceiling finish is the priority, such as living spaces, hallways or feature walls where conventional grilles are undesirable.\u003c\/p\u003e\n\u003ch3\u003eWhy we like it\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFits into conventional 4\" stud bays and disappears entirely once skimmed with plaster, paint, light wallpaper or fabric\u003c\/li\u003e\n\u003cli\u003eTwo-way design with one low-frequency transducer and two high-frequency transducers for punchy bass and a wide, crystal-clear frequency range\u003c\/li\u003e\n\u003cli\u003eIntegrated crossover delivers smoother overall balance and character\u003c\/li\u003e\n\u003cli\u003eRigid MDF back box isolates sound and minimises leakage into adjoining rooms\u003c\/li\u003e\n\u003cli\u003eAutomatic re-setting PTC circuit breakers protect against overload and allow the system to cool before resuming normal operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation notes\u003c\/h3\u003e\n\u003cp\u003eThe IV140 is fixed in place with self-tapping screws and connects via gold-plated sprung push-type terminals. It is built around a 9mm MDF construction with an integrated back box, and requires a cut-out of 591 x 350.5mm within a standard 4\" stud bay, with a mounting depth of 94mm and an overall depth (including grille) of 106mm. An optional WBIV140 pre-construction bracket is available separately for installations where the speaker position needs to be set before the wall or ceiling is finished. The nominal impedance is 8 ohms, with a recommended amplifier output of 20-50W (full range) or up to 100W when used with a minimum 80Hz high-pass filter.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency Response (-6 dB)\u003c\/td\u003e\n\u003ctd\u003e75 Hz - 18 kHz (sealed) \/ 55 Hz - 18 kHz (open back)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensitivity (1W@1M)\u003c\/td\u003e\n\u003ctd\u003e82 dB (when installed as directed)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal Impedance\u003c\/td\u003e\n\u003ctd\u003e8 ohms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum SPL\u003c\/td\u003e\n\u003ctd\u003e102.8 dBA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Handling (RMS)\u003c\/td\u003e\n\u003ctd\u003e50W full range (IEC268-5); 100W music programme with minimum 80Hz high-pass filter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommended Amplifier Requirements\u003c\/td\u003e\n\u003ctd\u003e20-50W (full range); 20-100W (with minimum 80Hz high-pass filter)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDrive Unit Complement\u003c\/td\u003e\n\u003ctd\u003e1 x low-frequency transducer, 2 x high-frequency transducer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOverall Dimensions (inc. grille, H x W x D)\u003c\/td\u003e\n\u003ctd\u003e642 x 401.5 x 106 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCut-Out Dimensions\u003c\/td\u003e\n\u003ctd\u003e591 x 350.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting Depth\u003c\/td\u003e\n\u003ctd\u003e94 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnection\u003c\/td\u003e\n\u003ctd\u003eSprung push type terminals, gold plated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFixing Type\u003c\/td\u003e\n\u003ctd\u003eSelf-tapping screw\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction Material\u003c\/td\u003e\n\u003ctd\u003e9 mm MDF\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColour \/ Finish\u003c\/td\u003e\n\u003ctd\u003eBlack painted, white membrane\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePre-Construction Bracket\u003c\/td\u003e\n\u003ctd\u003eWBIV140 (sold separately)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e9 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSold as\u003c\/td\u003e\n\u003ctd\u003eSingle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n","brand":"Monitor Audio","offers":[{"title":"Single","offer_id":55494590693715,"sku":"IV140","price":605.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1115\/1323\/9891\/files\/monitor-audio-iv140-invisible-in-wall-speaker-1-front.jpg?v=1792328932","url":"https:\/\/www.ceiling-speakers.co\/products\/monitor-audio-iv140-invisible-in-wall-speaker","provider":"Ceiling Speaker Warehouse","version":"1.0","type":"link"}
