PRV Audio 8MR500-4 BULLET 4 ohm 8" Mid Range Speaker
DESCRIPTION
- Product Overview
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.
Highlights
- 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!
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.
