Product Description
Manufacturer Part Number: 8MR400B-4 SLIM
Continuing PRV Audio's "pro audio on wheels" concept, the 8MR400B-4 SLIM 8" midrange is built to deliver the same performance as a professional loudspeaker. Featuring an aluminum phase plug for improved high frequency response, this driver is able to give high levels of output in installation locations where depth is at a minimum.
Key Features:
PRV Audio 8MR400B-4 SLIM 8" Midrange Speaker 4 Ohm
The 8MR400B-4 SLIM 8" midrange speaker uses a "bullet" phase plug made from pure aluminum to lower inductance and act as a heat sink cooling system for the voice coil. Machined to perfection for even sound dissipation the phase plug also improves off-axis frequency response. Beyond good looks, this cone is extremely light, providing excellent damping to keep an incredibly natural yet accurate sound with incredible efficiency.
An M-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. The suspension design of the 8MR400-4 SLIM features a single layer spider - which connects to the coil former with premium stitched lead wires. The cone is driven by a copper-clad aluminum wire voice coil providing high efficiency and excellent power handling.
This driver is constructed of high-performance characteristics and high-quality components to provide exceptional clarity, detail, and dynamic 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 midrange is the perfect option to replace those old 2-way or 3-way coaxial speakers. With less than 2-3/4" mounting depth, this driver is perfect installations where depth is at a minimum such as car doors and dash locations. Engineered and designed to easily transform a stock system into one that can deliver concert levels. The 8MR4000-4 SLIM is ideal for audiophiles seeking tremendous output without radical modifications.
