    for the HPF ( High Pass Filter ) we recommend

    Recommended Hi Pass Crossover**
    **For Full Power Handling
    120 Hz**

    for the LPF ( Low Pass Filter ) you can set according to your application, but we do not recommend to go over 7,500 Hz

    not for this model, we only have available recone kits for the neodymium models and aluminum basket model. all our basic models don't have a recone kit because of its price point

    This is a very nice speaker, lots of guys use them in my area and I have seen them in all kind of set Up’s, for it to be what’s considered there bottom of there line, it sounds better than other brands tops. Definitely need a good amp to run it, factory don’t cut it. I use it for a 01 suburban replacement and I had to by pass the factory amp with a new one.

    I replaced the woofers in my Behringer B802D 8″ powered speakers with this PRV 8MB450 I needed to do a screw hole modification in order for it to line up with the holes in the cabinets, but after I got it installed, all I can say is WOW!!!! these speaker’s have KICK and there much more sensitive then the original Behringer speakers. They need very little volume to sound loud and clear, even at low volume there Awesome!!

    I replaced my Crate Taxi 30 amp stock speakers with these and it made a huge improvement in sound quality…also changed the stock speakers of my Crate Limo 50 amps with PRV 4 ohm 10 in speakers…the results are amazing. I would strongly recommend PRV speakers to all seeking a fantastic upgrade in their sound….
