The 8MB450-4 v2, 8″ PRV Audio Pro Audio Midbass Woofer offers smooth lower response through a punchy mid bass range and a frequency response that takes your applications smoothly through the 7,500 Hz range.
Built for loud and clear vocal performance in tight, compact spaces. The new Version 2 has improved its motor and basket design. Now featuring a new copper-clad aluminum voice coil for low moving mass to increase efficiency.
Smooth vocal response combined with a strong midbass punch
Handles 450 Watts, guaranteeing endurance at loudest volumes
8″ Car audio Midbass speaker designed for Low Frequencies – 4 Ohm
The 2″ voice coil, durable spider suspension and the woven surround all supported by the sturdy steel basket ensure its ability to withstand long hours of operation without compromising the efficiency of the speaker.
A thick, yet light rigid cone ensures accurate response and power handling.
This midbass is perfect for applications where weight and space is limited, such as custom door panels, making this speaker a popular speaker choice among custom car audio builders.

*Nominal power handling is defined as the maximum RMS power that the speaker can handle in a 2-hour test with a pink noise with 6dB of crest factor and a bandpass filter with 12db/oct tuned in its usable frequency range. **Continuous Program Power (RMS) is the maximum power that the speaker can handle considering a regular musical program using our recommended filters, this power can be used to define the optimum amplifier power to provide a clean signal without clipping or saturation. ***Max Peak Power is the maximum power operation for the speaker, this power is allowed just for a few fractions of a second, usually found just on the peaks of the music. Keeping this power for a little longer timer will damage the speaker.
