SKU: 8MR500-4 BULLET 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: 95 – 20,000 Hz
  • Highest Quality Speaker with bullet design available
  • High efficiency: 95 dB guarantees High Output Levels
  • Handles 500 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 6.5″- 6MR400-4 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 + 8MR500-4 BULLET + TW500My-ND making the ultimate sound reproduction machine, with unbeatable sound quality and output.

    Q Is the 8MR500-4 BULLET speaker 2Ω stable with 250w RMS power? Or...can it handle 500w RMS at 4Ω? My amp offers - RMS Power 2Ω 250 x 4 and RMS Power 4Ω Bridged 500 x 2.
    Asked by Zachary Rosser on April 9, 2020 10:57 am

    These speakers are 4 ohms each. The amp is what needs to be stable at a particular ohm load to handle the ohm load of the speakers, not the other way around. If you use only 1 of these speakers it will be 4 ohms at the amplifier. If you use 2 of these speakers wired in parallel it will be 2 ohms at the amplifier. With that being said you will need about 500w each for these speakers. The amplifier you have will provide 500w to each speaker. If you use 2 8MR500-4 BULLET you can put one speaker on each side of the amp bridged to show the amplifier the 4 ohm load it needs to provide that 500w.

I Love them

The 8s are one of, if not my favorite speakers. Great sounding all the way around. I also have the 6" version of these and couldnt be any happier with the way they sound together
