IV140 Invisible In-Wall
The Monitor Audio IV140 invisible speaker is designed to deliver ‘best in class' audio performance in concealed in-wall and in-ceiling applications.
Concealed in-wall or in-ceilings, the speaker fits into all conventional 4" stud bays, leaving enough room for cabling. Once installed and skimmed with plaster, the speaker is completely out of sight, with paint, light wallpaper or fabric hiding it from view.
A large low-frequency transducer and two high frequency transducers provide punchy, high power bass and sound vibration. This two-way transducer design also features an integrated crossover to generate a wider frequency range and deliver crystal clear sound quality with smoother overall balance and character.
An integrated back box design isolates sound and ensures consistent, controlled performance. This rigid back box reduces sound emitted from the rear of the speaker, minimising leakage into other rooms.
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.
