Product description
DS18 PRO-CF8.4SL PRO 8" Slim Carbon Fiber Water resistant Cone Mid-Bass Loudspeaker 550 Watts Max 4-Ohm
The PRO-CF8.4SL is a water-resistant Pro Audio loudspeaker with amazing highs and comparable low mid bass frequency responses. This speakers versatility allows it to hit frequencies as high as 12.5KHz and as low as 60 Hz providing for an extreme full range of frequencies that all listeners will notice and enjoy!
The PRO-CF8.4SL is designed to deliver LOUD audio with striking clarity and remain durable in the worst of the elements. DS18’s current waterproof carbon fiber cone design and super strong rubber surrounds protect these speakers from damage sustained by use in harsh environments. This also helps increase the sensitivity level on these speakers so they play LOUD and clear on every use.
Although the speakers components are waterproof, the speaker itself is only water resistant so use in rough conditions should be avoided as much as possible.
The size reduction on this speaker also gives it high levels of functionality in a variety of applications. Easy-to-use push terminals help protect and secure wires.
The PRO-CF8.4SL handles great power; rated at 275 watts RMS and 550 watts max, you know this powerhouse of a speaker can get loud and clear!
