PRV AUDIO 6.5" Midrange Bullet Speaker 6MR400-4, 4Ω 400W High-Output Aluminum Phase Plug

This compact midrange blends pro-audio design with mobile installation requirements to deliver powerful, articulate mid frequencies for custom door and 3-way setups. The aluminum bullet phase plug aids heat dissipation while the robust motor and cone geometry let the driver handle sustained power, making it a practical upgrade for enthusiasts building loud, accurate systems.

What makes this midrange different from standard car speakers?

The 6MR400-4 uses pro-audio elements—like a machined aluminum bullet phase plug and a high-efficiency motor—to push more sound pressure without sacrificing clarity. Its parts and engineering prioritize linear midrange response and thermal management for extended high-power use.

• Machined aluminum phase plug for improved cooling and dispersion
• High-efficiency motor structure for greater output per watt
• Designed specifically for vehicle door and custom midrange locations

How much power can it handle and what load does it present?

This driver is rated for 400 watts of continuous program power and configured with a 4-ohm nominal impedance, matching common aftermarket amplifiers. The rating is intended for sustained music reproduction in automotive environments when paired with appropriate amplification and crossovers.

• 400 W continuous program power handling
• 4 Ω nominal impedance for straightforward amp matching
• Suitable for use in 3-way systems with separate woofer and tweeter

How should I use it in a car audio system for best results?

Install this midrange in a proper midband location (door panel or dedicated mid enclosure) with a protective grille and a well-chosen high-pass/low-pass crossover. Pairing it with a quality woofer and an appropriate horn or compression tweeter produces smooth frequency handoff and expanded dynamic range.

• Recommended in 3-way custom door systems for balanced output
• Use a crossover to protect the driver from extreme lows and highs
• Mount securely with vibration damping for cleaner midrange detail

What construction features improve durability and sound quality?

Durable materials and a focus on thermal control improve both reliability and sonic performance. The bullet-style phase plug acts as a heatsink, while the overall build supports consistent movement and minimal distortion at high output levels.

• Aluminum phase plug for heat dispersion and smoother high-mid response
• Sturdy motor and suspension for controlled cone excursion
• Optimized cone geometry for clear midrange articulation

Who is this for: The PRV AUDIO 6MR400-4 suits car audio enthusiasts and installers who want a compact, high-output midrange for custom 3-way door systems or competitive builds. It’s ideal for those who demand strong midband presence, reliable power handling, and integration with professional-grade components without expanding to larger mid drivers.
