DSPPA DSP-922 S CEILING SPEAKER 8 W / 70-100V

The DSP922 is a ceiling speaker with a 70v/100v transformer built in. The 70v/100v transmission is realized in a high-voltage, low-current mode, which makes longer distance transmission and parallel connection of multiple loudspeakers possible.

● Built-in 100v/70v transformer
● In-ceiling type loudspeaker
● 4.5” paper cone waterproof driver
● Rated power output at 4W-15W
● High sensitivity(88±2dB)
● Made of high-class steel
● Leaded wire case for fireproofing
● Fast installation by spring clip

The built-in 4.5” speaker driver is designed of wide frequency response (250-16,000Hz), the multiple terminals 4W, 8W & 15W can be applied to different occasions vary in area sizes and background noises; It is made of high-class steel and fixed by stamping, which ensures long-term durability, and will never be out of shape; Equipped with leaded wire case which is hard to burn for fireproofing; Spring clip clamp makes the easy and secure installation possible; Driver surround excellent damping, long life, clear and sonorous sounds.

It is an ideal choice for industrial and commercial applications in hotel, school, office and factory where background music and paging is needed.

Most compact of the JBL ceiling speakers, the Control 24C contains a coaxially mounted 4" woofer and 3/4" titanium-coated tweeter, providing high-fidelity sound over an extremely wide coverage area.
