    questions on tweeters

    hihi. i'm a noob trying to upgrade my car tweeters. i have a crossover network wired up already.

    can i ask if any of you guys tried to fix some of these non-car tweeters in your car?
    like this one:

    they are alot cheaper. and seem for value for money than car tweeters.

    thanks!

    They will probably work but you got to look at (among other things) the impedance of the speaker as compared to what your amp or HU can handle.

    I'm rusty on which impedance car speakers are (either 8 or 4) so you might want to find that out and compare it to this speaker.

    most car speakers are 4-ohm, some higher end ones are 2-ohm. 8-ohm is common for home speakers

    Most car stuff is 4ohm, whereas the PE drivers are typicalls 6 - 8 ohm. If you know what you are doing, you can potentially piece together a system that will cost significantly less than a store-bought product. I built my own component speaker system from PE for ~$100 with some higher quality caps, inductors, dayton tweeters, and audax aerogel midbass. It's 6 ohms, but runs off my amp just fine. But if you are adding a tweeter to an already designed crossover network, then make sure the impedance matches otherwise your freq curve will change.

    that reminds me, i need some new mids....

    alot of people have used large format tweeters like that. IMO, the largest hurdle to overcome is mounting it-- because they are just so big--once you get it mounted though, the change in resistance can be compensated for with different settings.

    Yea most of the PE tweeters are huge. Take a look into the Dayton ND20FA tweeter, that's the one I use. I picked it because it's very small and you can mount it from the surface.

    I run Selenium tweets and mids in my "monster PT" they are 8 ohms and very efficient, I run them off of a 4 channel amp 115 per side but less since the 115rms is 4 ohms, they get very loud!

    I also run Dayton mids and Vifa tweets up front, but they are 4 ohms mdels.

    8 ohms tweets are fine, as long as you keep the crossover point safe for them and watch the efficiency of them, usually pretty high.
