PRV AUDIO 8MR450A 8 in Midrange Speaker - High Output, Low Distortion

In this review of the PRV AUDIO 8MR450A midrange speaker, the bottom line is simple: it is built for installers and DIY builders who need a compact, high-output midrange that fills the crucial mid band with low distortion. The reviewer found the speaker's shallow 3.21 in mounting depth and solid mechanical design make it easy to install in pro cabinets, car doors, or compact satellite enclosures, while the construction choices deliver a clean, extended response that complements both three-way pro systems and two-way satellite setups.

Key Features

• Shallow mounting depth: The 3.21 in mounting depth lets this midrange fit into tight cabinets and door panels without sacrificing cone area.
• Efficient voice coil: The 38 mm copper clad aluminum voice coil wound in double layers offers thermal stability and sustained power handling during extended use.
• Reduced inductance: A copper sleeve on the pole piece smooths the high-frequency response and helps reduce phase anomalies in crossover regions.
• Durable suspension: The triple roll cloth surround and fiber pressed paper cone give a controlled, smooth midrange with reliable mechanical longevity.
• Wide usable band: Designed to cover roughly 100 Hz to 6,000 Hz, it works as the critical mid driver in three-way systems or as a full-range mid in compact speaker concepts.

Who It's For

The 8MR450A suits audio professionals building high-output pro sound systems, installers who need a dependable midrange for three-way cabinets, and car audio enthusiasts looking for a robust door speaker that improves mid clarity. Its efficient coil design and copper sleeve make it attractive where heat and inductance control matter.

Less appropriate choices include those wanting a full-range speaker for single-driver systems or customers who need extreme low-bass extension below 100 Hz; this driver is optimized for the mid band and is best paired with a suitable woofer and tweeter in a multiway system.

Pros & Cons

Pros

• High output with low distortion thanks to efficient voice coil construction and a well-vented former.
• Compact 3.21 in mounting depth that simplifies integration into enclosures and car doors.
• Durable cone and triple roll surround provide smooth frequency response and mechanical reliability.
• Versatile frequency coverage that suits three-way systems and two-way satellite concepts.

Cons

• Not intended to replace dedicated woofers for frequencies below 100 Hz, so a subwoofer or larger woofer is required for deep bass.
• Single-driver purchase requires a matching crossover and complimentary drivers for a complete system.

Frequently Asked Questions

Can this driver be used in car doors?
Yes, the shallow 3.21 in mounting depth and robust surround make it suitable for many car door installations when fitted with the right mounting adapter and enclosure considerations.

What frequency range does it cover?
The 8MR450A is designed to operate effectively from about 100 Hz up to 6,000 Hz, making it ideal as the mid driver in three-way systems or as a mid/woofer in compact two-way satellites.

Is a crossover required?
For best results in multiway systems, use a properly designed crossover to hand off lows to a woofer and highs to a tweeter so this midrange can operate within its intended band.
