About: PRV Audio 6MR400-NDY-4 BULLET 6.5″ Neodymium Midrange Bullet Loudspeaker - 4 Ohm (Each)

The MR NEODYMIUM BULLET was conceived with one goal in mind: High-Performance! Featuring a sleek black aluminum phase plug (Bullet), this mid is built like a professional midrange loudspeaker, but it has been designed for and optimized for car audio applications, as we call Pro Audio On Wheels®! By combining key elements from PRO Audio performance and Car Audio practicality, we have developed a NEW type of high efficient compact midrange speaker that is able to give extreme high levels of output for your custom door.

A M-roll cloth surround, combined with an optimized fiber pressed paper cone, ensure the speaker’s frequency response is smooth and extends to the high range making an easy transition to a super tweeter, but according to customers, the high-frequency response from this speaker does NOT need support from a tweeter! Its low-mass yet stiff cone helps provide clean, detailed, high-impact sound reproduction. to ensure the speaker’s extended frequency response to 14,000Hz and strong vocal presence.

You can expect outstanding sound quality and realistic sound reproduction in the smallest profile. There’s no better value in high-performance bullet speakers than the 6MR400-NDY-4 BULLET loudspeaker. With a shallow and versatile footprint that only measures 2.68” in depth, we’ve designed a midrange loudspeaker that gives you everything you need without sacrificing performance. The rare-earth neodymium motor combined with other fine materials will resolve the finest details in audio, demanded by car audio and motorcycle custom builders.

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.
