About: PRV Audio 6MR200A-4 6.5" 200W RMS Midrange Speaker - 4 Ohm (Each) 

PRV Audio’s ALTO Series were carefully crafted and voiced to reproduce a natural, smooth sound while remaining dynamic. To get the superior fidelity, a special composite cone is used to smooth frequency response and to keep the moving mass low, increasing the efficiency. The 6MR200A-4 midrange speaker is our solution for PROAudioOnWheels® for Car audio systems.

To ensure absolute signal fidelity, a cloth sealed surround is combined with a carefully crafted Kevlar-loaded paper cone. Additionally, a vented pole piece allows heat to escape for reduced power compression.

The 6MR200A midrange speaker is the evolution of the 6MR250A, this unit was designed with the goal of producing the highest possible output from a compact design without sacrificing performance, with only 2.24″ mounting depth.

This professional midrange speaker is purpose-built to cover from 100 Hz to 6,000 Hz in three-way speakers, but also works great as a midrange in a bass guitar speaker, as well as a woofer in two-way satellite speaker concept or even as a high output car audio door speaker.

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.
