Includes: 2x 6MR600X-NDY-4 Neodymium Midrange Loudspeakers Car Pro Audio 4 Ohm - 1200 Watts Package - 600 Watts each 6MR600X-NDY-4X-treme midrange performance is what the PRV Audio 6MR600X-NDY-4 is all about. The 6MR600X-NDY-4 from PRV Audio showcases the breakthrough advances of our product line like no other. After significant development, and assembling top of the line components, we have created a midrange loudspeaker that offers long lasting play, even during intense use, as well as outstanding durability.Highlights2″ Inside/Out voice coil wound on a hi-temp former, 4 Ohm600 Watts RMS Power Handling, with a 97.5 dB Sensitivity, capable of generating very high output!Low inductance and extended frequency response with wide directivityNew Generation of Neodymium Magnet StructureIdeal solution for compact full-range applications demanding high acoustic outputCoaxial Performance from a single speakerThis is the ultimate midrange loudspeaker, the 6MR600X-NDY-4’s output on upper midrange frequencies compares to a compression driver! The naturally damped paper cone gives this speaker the ability to reach up to 13,000Hz.Also, its extreme output eliminates the need for a high frequency compression driver in the system, providing 2-way coaxial performance from a single speaker!Its high energy, rare-earth neodymium motor, combined with other fine materials, were chosen to increase sensitivity and power handling to deliver the finest details in audio, as demanded by most audiophiles and custom builders in the car audio and motorcycle custom builders.This midrange takes performance to the next level with its wide frequency bandwidth, high output levels between 3,000 to 10,000Hz, and unbelievable 600 Watts RMS music power handling, completely eliminating the need for a compression driver on your system! This midrange incorporates a 2” double layered copper clad aluminum wire voice coil, and a symmetrical inductance profile. Its 11 mm winding length also ensures high heat dissipation and high sensitivity, even on high power, and with minimum distortionEverything about this speaker has been designed for reliable and consistent high output levels, even when driven to its limit, allowing you to achieve high fidelity sound at low distortion for the best possible listening experience.GENERAL SPECIFICATIONSNominal Diameter6″ (152 mm)Nominal impedance4 OhmNominal Power Handling*300 WattsContinuous Program Power (RMS)**600 WattsMax Peak Power***1200 WattsSensitivity 2.83V at 1m97.5 dBRecommended Hi Pass CrossoverFor Full Power Handling160 Hz12db Per Octave CrossoverFrequency Response90 – 13,000 HzVoice Coil Diameter2″ (50 mm)Voice Coil WireCCAWVoice Coil Winding Depth11.0 mmFormer MaterialKaptonMagnetic Gap Depth8.0 mmFrame MaterialDie Cast AluminumEXTRA INFOOverall Diameter6.48” (164.5 mm)Front Mount Baffle Cutout5.63” (143 mm)Mounting Depth3.09” (78.5 mm)Overall Depth3.43” (87 mm)Net Weight4.63 Lbs (2.1 kg)Shipping Weight5.00 Lbs (2.3 kg)Carton Dimensions W x L x H7.0”x 7.0” x 4.25” (178 x 178 x 108mm)
