    Q What kind of amp does this speaker need to work?
    Asked by Anonymous user on August 24, 2020 7:07 pm

    For this compression driver we recommend 75-150w each. Which amplifier you use will determine which amplifier you will use. You can use a Timpano Audio TPT-800.4 2 ohm for either 2 or 4 of them ran in pairs, in parallel and bridged at the amplifier.

    Q Are they water proof because i want to put it on the outside of my car in the grill ?
    Asked by Matt P on August 29, 2019 9:53 pm
    Answered by the admin

    This driver has a phenolic diaphragm which is weather resistant - it will not absorb moist and it reverse phase-plug design it will not allow water to get inside of the magnet gap

    we do not recommended to play while there is water inside, but if it get wet and the driver is mounted on a way that the water can come out, you should have no problem
