About: PRV Audio 8MR450CF-4 8" Midrange Loudspeaker - 4 Ohm (Each)

The 8MR450CF-4 series was designed for Power sports applications, featuring a water-resistant design to ensure optimum performance taking into account the effects of the outdoor environment! Ideal for upgrading your sound system in your boat, UTV, 4-wheeler, or motorcycle, this midrange speaker becomes the new standard in vocal reproduction for outdoor applications. Constructed of high-end materials like a carbon fiber cone, high-temperature voice coil, and huge neodymium magnet, this driver produces natural sound with remarkably low distortion.

The tailored response of the 8MR450CF-4 comes from its exotic yet supremely engineered carbon fiber cone that delivers the signature PRV audio combination of depth and accuracy on vocal reproduction. Beyond good looks, this cone is extremely light, surprisingly rigid, and provides excellent damping to keep narrow peaks under control, resulting in an incredibly natural yet accurate sound.

Note:  

• Nominal power handling is defined as the maximum RMS power that the speaker can handle in a 2-hour test with a pink noise with 6dB of crest factor and a bandpass filter with 12db/oct tuned in its usable frequency range.
• Continuous Program Power (RMS) is the maximum power that the speaker can handle considering a regular musical program using our recommended filters, this power can be used to define the optimum amplifier power to avoid a clean signal without clipping or saturation.
• Max Peak Power is the maximum power operation for the speaker, this power is allowed just for a few fractions of a second, usually found just on the peaks of the music. Keeping this power for a little longer timer will damage the speaker.
