PRV Audio Local Speakers

PRV AUDIO Vocal Speakers....  
This may not make sense initially, but a high-quality speaker will have less bandwidth than a lower quality speaker... (for the most part)
Just like a 3- or 4-way system is always better than a 1- or 2-way system.  The narrower the bandwidth the speaker must play the cleaner it will sound.  This will also keep you from asking the speaker to play up to its upper and lower frequency limits which are where it starts to sound "forced" to play those frequencies
Pro Audio speakers are nothing new to car audio, but I see consumers not really knowing how to properly use them and having some issues which is understandable.  These are totally different than your standard coaxial speaker

If you look at the graph on the 6mr500ndy, which sounds amazing, you'll see that it can play from 90hz to 12,000hz... but if you narrow it down to what is plays "best" and more "naturally" it’s closer to 200hz to 10,000hz.   Yes, it can play down to 50hz but not efficiently and not as well as 200 and up. Very low volume that would be fine but in what we do with the speaker you will want to cross it over closer to 200-300hz

I get a lot of PMs asking if this speaker will pick up where my subs leave off?   … around 60-80hz.  I say no but the specs say "yes”. 99-13k so that may be a little confusing if you don’t look at the graph and understand what information it has in it
So, for someone interested in using this speaker as a voice speaker, which I HIGHLY recommend, you will also need a "midbass" speaker to go with it such as a 10mb800 or 10mb500 or 8mb450.     
This leads me to another piece of information.  PRV model numbers have an "MR”, “MB", "SW" or "W" in between the size of the driver and wattage of the individual speaker. MR=midrange

MB=midbass
W=woofer 
SW=subwoofer
This is a general guideline for what the speaker is geared towards. That doesn’t mean an 8mb450 can’t be used for midrange or and 8mr400 can’t be used for midbass.  That is where the graph and interpretation of the graph comes into play
There is a lot more that goes into designing your front stage or your "voice" speakers that one of these days I’ll try and have a more in depth write up.   The possibilities are endless...
