The MR BULLET was designed with a single objective: High Performance!
Featuring an Aluminum Phase Plug (Bullet), this midrange speaker is constructed like a professional loudspeaker but designed specifically for the mobile audio market, earning the name Pro Audio On Wheels®! By merging elements of PRO Audio and Car Audio, we've created a new type of highly efficient midrange capable of delivering high output levels for your custom door setup.
**Wide Frequency Range:** 145 – 12,500 Hz
**Premium Quality:** Highest quality speaker with bullet design
**High Efficiency:** 95 dB ensures high output levels
**Power Handling:** Handles 400 Watts, enduring the loudest volumes
**Heat Dissipation:** Vented air pole piece
**Even Sound Distribution:** Center phase plug
**Impedance:** 4 Ohms
**Available Sizes:** Also available in 8″ – 8MR500-4 BULLET and 6×9″ – 69MR500-4 BULLET
The “bullet” phase plug, crafted from pure aluminum, acts as a radiator cooling system for the voice coil and is precision-machined for even sound dissipation. Beyond its good looks, this extremely light cone offers excellent damping, ensuring a natural and accurate sound.
A triple-roll cloth surround, combined with an optimized fiber-pressed paper cone, guarantees a smooth frequency response that extends to high ranges. This design facilitates an easy transition to a super tweeter, though according to customers, the high-frequency response from this speaker often doesn't require additional tweeter support!
The suspension design of this midrange speaker includes a single-layer spider connected to the coil former with premium stitched lead wires. It is powered by a copper-clad aluminum wire voice coil, ensuring high efficiency and excellent power handling.
With high-performance characteristics and top-quality components, this speaker delivers exceptional clarity, detail, and dynamic sound. You can expect an outstanding sound stage and realistic sound reproduction, all at a great value. This speaker sets a new standard for high-performance bullet speakers.
Built to handle 400 Watts of Continuous Program Power (RMS), this midrange is ideal for a 3-way custom door system. Pair it with the 10W1000-NDY-4 and the TW450Ti-ND-4 to create the ultimate sound reproduction machine, delivering unbeatable sound quality and output.

- *Nominal Power Handling:* Defined as the maximum RMS power the speaker can handle over a 2-hour test with pink noise featuring a 6dB crest factor and a bandpass filter with 12dB/oct tuned to its usable frequency range.
- **Continuous Program Power (RMS):** The maximum power the speaker can handle during a regular musical program using our recommended filters. This rating helps define the optimal amplifier power to provide a clean signal without clipping or saturation.
- ***Max Peak Power:** The highest power level the speaker can handle for brief moments, typically during music peaks. Sustaining this power for longer periods will damage the speaker.
