Kramer Yarden IH-1 2-Inch Hidden In-Wall Speaker

The Yarden IH-1 uses a polypropylene flat membrane driven by a 2-inch voice coil with a double-magnet neodymium motor, built into a shallow in-wall enclosure for background audio where a visible grille speaker is not wanted. At 83dB sensitivity and a 120Hz to 20kHz response, it covers speech and background music rather than full-range program material.

A selectable 8-ohm/70V/100V transformer tap matches it to either a dedicated zone amplifier or a building-wide constant-voltage paging line, and its shallow 5.7cm mounting depth lets it fit walls where a deeper in-wall speaker cannot.
