Niles presents the CM4PR-- a high-end 4" 2-way ceiling-mount speaker the company says is ideal for smaller spaces where customers demand the reduction of sound bleed-through.
Limiting sound transfer is a rear wave control enclosure, which Niles says also enchances acoustic performance. A mineral-filled polypropylene cone improves bass response (while lowering distortion) and a 1" fluid-cooled Teteron dome tweeter provides ultra-wide dispersion.
Frequency response is 70Hz to 21kHz +/- 3dB, plus 8 ohm nominal and 6 ohm minimum impedance.
Magnetically-attached MicroThin speaker grilles allow for quick installation. Weighing 1.2kg, the speaker needs a hole cutout of only 11.75cm, with a depth behind ceiling of 8.4cm.
