DS18 Marine & Powersports Mid-Bass Loudspeaker Motorcycle 500W 4 Ohm PRO-CF6.4SL

The PRO-CF6.4SL 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 80 Hz providing an extreme full range of frequencies that all listeners will notice and enjoy! The PRO-CF6.4SL was designed to deliver LOUD audio with striking clarity and remain durable in the worst of the elements. DS18s 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.
