Product Overview
JBL CONTROL 28-1-WH Overview
Designed by JBL, these Control 28-1 loudspeakers are two-way 8" indoor/outdoor monitors featuring weather-protected circuitry, natural and powerful representations of the frequency spectrum, white enclosures, and JBL's proprietary InvisiBall mounting hardware. This hardware allows you to install the speakers through a hidden access point behind its logo badge. As such, the Control 28-1 suitable for venues, health clubs, theme parks, cafes, or anywhere where foreground/background music—and paging—is a necessity.
These monitors are capable of handling 240W of programmatic material at 8 Ohms, and feature a built-in multi-tap transformer for operation on distributed speaker lines. With an SPL of 112 dB, you can blast these speakers pretty loudly as well, while their cone geometry ensures a pleasurable listening experience in both on- and off-axis situations. Additionally, their PEI diaphragms render a smooth high-frequency response. But sound is not the only consideration: Kapton voice coil formers, JBL's WeatherEdge rubberized extensions, and a durable cabinet construction provide protection against heat, rain, wind, or anything else the elements might throw at you in the coming years.
Also, while the Control 28-1 comes in a white finish, it doesn't have to stay that way: these speakers accept a variety of finishes and pigments to match any surrounding.
