About: PRV Audio 6MB100-4 6.5" 50W RMS Midbass Loudspeaker - 4 Ohm (Pair) 

We have combined the PRO audio and high fidelity audio into a new type of driver aimed at delivering high levels of clean output from stock speaker locations.
The 6MB100-4 speakers can be used to transform a stock system into a concert level experience without cutting up interior panels. The shallow mounting depth of 2.32″ is designed for easier installation with its standard frame size that fits in many OEM speaker locations.

These Pro Audio On Wheels® speakers will handle 100 Watts of Continuous Power and 50 Watts RMS power with a Sensitivity of 90 dB and 90 – 10,000 Hz of Frequency Response. This PA Style speaker is a great upgrade for listeners wanting to go well beyond the standard factory upgrade.

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.
