vifa tweeters

I have a pair of vifa dx 25 tweeters I would like to add to the rear of my Matrix. I have a sony deck and I have the hpf frequency set at 80. Now the question I have is do I need to make a crossover to protect the tweeter from damage any thoughts?

    It absolutely needs to be high passed, a single capacitor would be a starting point, and you will most likely have to attenuate the level as well.

    That tweeter is very robust, and a single cap might work. What Fc do you want to have? Something like a 10 uF cap might work. I used that tweeter with a 3rd order - 10uF - .25mH to ground and 10 uF, which resulted in a 2.4 Khz Fc.

    But Chahly - Stahkist don't want speakers that look good, Stahkist wants speakers that sound good!

    Yeah I don't know much about crossovers,I can follow a diagram. But thats about all the knowledge I have.

    I have a 10 uf cap here and a .25 winding and don;t know what fc I need to have.

    I have installed a pair of the dayton AMTPOD tweeters in the Acura using the supplied cap and have not had any issues . Side note , Im not running insane power to them just power from the Blaupunkt head unit.

    Just use those 2 components, with possibly a resistor to set the level. That should protect the tweeter enough. Give it a listen and see if you like it.

    Why do you want to add tweeters to the rear sound stage?

  • Tony455Tony455

    Yeah that's what I intended ,sub at the back door. 6.5 inch in 4 doors and tweeters in the front at window height.

  • Tony455Tony455

    Just because I have an extra set and would like to see what it sounds like. And I'm getting bored. Been doing a bit of reading and they say 2.5 is a good fc for these.

    I was a certified IASCA judge for many years and no winning sound system had tweeters in the rear. Full rangers at best.

    No, I don't do competions but I thought it might sound good. I like a variety of music and since it's a wagon I thought it might add to the sound stage.

    Suby?

  • Tony455Tony455

    So any ideas on a resistor value for that 10 uf .25mh crossover.

  • 6thplanet6thplanet

    Tony, does the 455 in your name come from any particular Pontiac? Your tweeter in the back idea makes me wonder if you come from an era of Jensen triaxials.

  • Tony455Tony455

    I cetainly do, peace love and good tunes lol

  • Tony455Tony455

    And to answer your first part, olds toranado.

    If it's a 455 I'm guessing earlier model , please don't cut into any panels unless they are roached out. Makes Nick sad.

    Not enough metal in the new cars today, you would mess with the strucuarl intregrity. 69 was a good year,gas was cheap.
