Know before you buy
The speaker is designed to be installed flush with your wall or ceiling studs. Once mounted, it is covered with a thin layer of plaster or drywall compound, allowing you to paint or wallpaper directly over the surface so the speaker disappears into the room's decor.
Yes, the IV140 is specifically engineered to fit into standard 4-inch stud bays. With an overall depth of 4.19 inches, it is optimized for seamless integration into typical residential wall and ceiling framing.
The integrated back box is a critical component that provides a controlled acoustic environment for the drivers. It ensures consistent performance regardless of the wall cavity conditions and significantly minimizes sound leakage into adjacent rooms.
The IV140 has an RMS power handling of 50 Watts and an 8-Ohm impedance. A standard high-quality home audio amplifier or receiver will be sufficient to drive these speakers effectively for most listening environments.
When using the sealed back box, the frequency response is 75 Hz to 18 kHz. If you choose to install the speaker in an open-back configuration, the low-frequency response extends down to 55 Hz, providing slightly deeper bass performance.
The IV140 features built-in automatic circuit breakers designed to protect the internal components from overload. If the system is pushed beyond its limits, the protection circuit will engage to prevent damage to the drivers.
