SKU: 6MR400-4 BULLET-PARENT Categories: , Tags: ,



The MR BULLET was conceived with one goal in mind: High-Performance!

Featuring an Aluminum Phase Plug (Bullet), this mid is built like a professional mid range loudspeaker, but it has been designed for use in the mobile audio market, as we called it Pro Audio On Wheels®!! By combining elements from PRO Audio and Car Audio, we have developed a NEW type of high efficient mid range that is able to give high levels of output for your custom door.



  • Built to Perform at Wide Frequency Range: 145 – 12,500 Hz
  • Highest Quality Speaker with bullet design available
  • High efficiency: 95 dB guarantees High Output Levels
  • Handles 400 Watts – Endurance at Loudest Volumes
  • Vented Air pole piece for heat dissipation
  • Center phase plug for even sound distribution
  • 4 Ohms Impedance
  • Also available in 8″ – 8MR500-4 BULLET
    and 6×9″ – 69MR500-4 BULLET

The “bullet” phase plug is made from pure aluminum acting as a radiator cooling system for the voice coil and machined to perfection for even sound dissipation. Beyond good looks, this cone is extremely light, providing excellent damping to keep an incredibly natural yet accurate sound.

A triple roll cloth surround, combined with an optimized fiber pressed paper cone, ensure the speaker’s frequency response is smooth and extends to 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!

6MR250B-4 SLIM

The suspension design of this mid range features a single layer spider – which connects to the coil former with premium stitched lead wires, all being driven by a copper-clad aluminum wire voice coil providing high efficiency and excellent power handling.

Its high-performance characteristics and high-quality components provide exceptional clarity, detail, and dynamics sound. You can expect outstanding sound stage quality and realistic sound reproduction for a great value. This is the new standard of value in high-performance bullet speakers.

Built to perform and able to handle 400 watts of continuous power, this mid range is the perfect match on 3-way custom door system such as:

10W1000-NDY-4 + 6MR400-4 BULLET + TW450Ti-ND-4 making the ultimate sound reproduction machine, with unbeatable sound quality and output.

6MR400-4 BULLET...Wow

Previously bought 6.5 adapter for my 2009 Harley-davidson Electra Glide Classic and was told to check out PRV. I purchased a set of the 6MR400-4 BULLET...installed them (no amp yet)...then I turned it on and up. The clarity with these speakers at max volume with no amp is amazing. Even has great sound with full face helmet...visor down...running 85 down the road. Don't know if the video will do them justice. I will be purchasing an amp and possibly some tweeters shortly. I highly recommend these speakers.

Upgraded from 100 RMS MR slim 6.5

Honestly the 100 RMS MR slims I bought first sounded pretty good but when I seen these 200 RMS bullets for such an affordable price I had to upgrade and boy do they make a difference. I have 4 of these in my visor pods on a 800×4 Taramp. I slapped the PRV grills on them and they look and sound Amazing. These things are small but pack power the vocals are so loud and clear, I would definitely recommend especially if you have subs already so you have vocals to balance that bass

Trevor Lanman

Never really got into audio but I’ve had kicker, skar, and Bose before, but these prv speakers give me hearing problems how loud they are. I run 4 on a 1000 amp for my front doors and it’s the most crystal clear audio out of all of my friend group, this is compared to skar and audio legion
