About: PRV Audio 8MB500 8″ Midbass Loudspeaker - 8 Ohm (Each) 

The 8MB500 was designed to provide outstanding durability and strong midbass punch. This 8″ professional loudspeaker midbass is purpose-built to cover the critical low frequency range in a home speaker setup, but also works great as a door speaker in car audio applications.

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 the latest technology we can increase tremendously the magnet field without huge magnet, making this midbass one of a kind, with large diameter motor, not bulky yet capable of handling high power!

Featuring a naturally damp paper cone and special coated dust cap, makes this professional speaker able to cover a wide range of frequencies from 75 Hz to 7,500 Hz in three-way systems. Developed to perform well in tight enclosures, its triple roll surround keeps its cone travel linear at high mibdass excursion. The right combination of cone and suspension gives this speaker an excellent human vocal reproduction with dynamic midbass sound.

Note:  

• 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 avoid 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.
