Features
The 8MB500-4 was designed to provide outstanding durability and strong mid bass punch. This 8″ midbass car speaker is purpose-built to cover the critical low frequency range in a custom car stereo setup.
Optimized to work great as a door speaker in car audio applications. If you need a speaker at 8 Ohm for a large custom door panel, we have the 8MB500.

- A deep and punchy midbass response along with a strong vocal response
- Car audio midbass speaker that offers smooth lower response through a punchy mid bass range
- Natural paper cone and cloth triple roll surround for smooth response
- Handles 500 Watts, guaranteeing endurance at loudest volumes
- Impressive choice for high output custom car audio systems – 4 Ohm impedance

The latest technology enables us to increase the magnet field dramatically without using huge magnets, making this midbass one of a kind, with a large motor diameter that is not bulky, yet is capable of handling high power!
This is a great choice for a 3-way system, where you can combine a super tweeter with a subwoofer to get a full spectrum of audio.

Built with premium components to ensure absolute high sound fidelity, one of which is its compact push terminals, which connect to its silver tinsel lead wires attached to its high temperature CCAW voice coil.

Featuring a naturally damp paper cone and special coated dust cap, it makes this midbass speaker able to cover a wide range of frequencies from 75 Hz to 7,500 Hz.
Developed to perform well in tight enclosures, its triple roll surround keeps its cone travel linear at high mibdass excursion. Using the right combination of cone and suspension, this speaker is able to reproduce human vocals with dynamic midbass punch.
PRV 8″ Midbass Speaker 8MB500-4 Car Audio 500 Watts / 4 Ohm
Recommended Amplifier configurations and crossover points:
2 Speakers – 1x MDX1200.2 1 Ohm, Bridged both speakers in parallel
4 Speakers – 1x MDX1800.1 1 Ohm, 4 speakers in parallel
Recommended HPF using PRV Digital Signal Processor DSP when using up to 500 Watts RMS musical power
- 95 Hz at 12 dB per octave filter Crossover / BT12
- 85 Hz at 18 dB per octave filter Crossover / BT18
If you have a super tweeter on your system the recommended LPF is 7,500 at 18 dB per octave filter Crossover / LR18 but you may set it lower to blend in better depending on the other components in your system, or you may not use a LPF at low power to take advantage of its high frequency response.
