Monitor Introduces IV140 ‘Invisible’ In-Wall Speaker Monitor Audio has introduced the IV140, a speaker designed to deliver high performance audio in concealed in-wall and in-ceiling applications.By RS Staff Published: February 27, 2017 ⋅ Updated: April 15, 2019 Monitor Audio has introduced the IV140, a speaker designed to deliver high performance audio in concealed in-wall and in-ceiling applications. “Installers, architects, designers, and clients are increasingly attracted to the benefits of an invisible audio soundstage,” said Monitor Audio’s technical director, Dean Hartley. “A completely concealed solution appeals to designers and clients who want to listen to music but also want to preserve the interior aesthetic. For installers, invisible speakers can be a real problem-solver on many projects but they must be fitted by a professional. Meanwhile, everyone is looking for high-quality invisible speakers that deliver the best possible audio performance they can buy. Using all our 40 years’ experience, we’ve built the IV140 to bring both ultimate discretion and high performance to the category. Installers can now fit an invisible speaker that integrates all Monitor Audio’s traditional performance benefits and take advantage of a significant and growing market opportunity for invisible speakers.” Monitor Audio IV140Monitor Audio’s IV140 features a large low-frequency transducer for punchy, high-powered bass along with two high-frequency transducers, which are bonded to a flat, soft polymer membrane surface to produce sound vibration. This two-way transducer design also features an integrated crossover in the same way as a conventional high-performance speaker to generate a wider frequency range. The result is clear sound quality with smoother overall balance and character. The audio experience is further enhanced by Monitor Audio’s unique hybrid back box design for the IV140, which isolates sound for more consistent, controlled performance, regardless of placement. This rigid back box reduces sound emitted from the rear of the speaker, minimizing leakage into adjoining rooms. The design effectively limits low frequencies below 75Hz, for instances such as when the IV140 is deployed in home cinemas with an additional subwoofer. For projects where more low frequency extension is required, the rear cover can be removed to create an open-back speaker. At just 3.25 inches (95mm) deep, (83.5mm fitting depth), the IV140 will fit into all conventional 4-inch stud bays within walls, leaving enough room for cabling, and will also fit within ceilings. Once skimmed with plaster, the speaker can be finished with paint, light wallpaper, or fabric. Monitor Audio’s IV140 is protected against overload by automatic re-setting circuit breakers (PTC). These will attenuate output for a specific time period to allow the system to cool until normal operation can safely resume.
