    capacitor size for 800hz-15khz horn midrange/tweeter?

    Recently bought a pair of horn midrange/tweeters which play across 800hz-15khz and I'm not sure what capacitor size to put on it because it plays down to 800hz. Theyre rated at 4~8ohm impedance.

    Any recommendations?

    Cheers.

    are you talking about building your own crossover ?

    I'd say so. I have no experience at all with these kinds of speakers, been in subs for the past year or so.
    I bought some 2khz-20khz super tweeters as well and they came with 2.2uF caps to put in series so I assume I'd need some for these as well.

    Cheers.

    What are they? What range do you want to play them? What else will be running?
    I think this is a case for active control.

    the whole system is 3 12"s with the LFP set to 80hz
    4 6x9"s 45hz-20khz
    2 tweets 2k-20k
    2 tweets 800hz-15k

    I'd like to play these horns across the whole range of 800-15k if possible

    Seems like an awful lot of highs if you ask me. But to answer your question you'd need to know the impedance of the horns at 800 hz. You can't assume it's 4 ohms or whatever nominal number is in the specs. Ideally you'd want an impedance vs. frequency plot which you might be able to get from the manufacturer.

    Your best option would definitely be an active crossover. How do you intend to amp them?

    I doubt I'll be able to find the frequency response graphs because they're cheap tweets I found overseas and couldn't find much info on them.

    I have an amp for the subs, the 6x9's off the head unit because they're only 45wrms and the tweets are gonna be on a 4 channel amp that my 6x9's are currently on with 2 pairs of channels bridged. I plan on running pairs of tweets in parallel on each bridged channel as to reduce the impedance and get more power to them.

    what if I put them on without capacitors and I just set the HPF on the amp to 800hz?

    Yup, that'd work.

    sweet, but i'd like to know why I can't assume it's just 4 ohms at 800hz?
    wouldn't that be staying on the safe side?

    Re: capacitor size for 800hz-15khz horn midrange/tweeter?

    Usually the nominal impedance is specified at 1000 Hz, and 800 should be close enough so you'd be OK. If you want to go that route, try a 50 uF cap

    calculator here: Passive Crossovers, Capacitor and Coil Calculator

    But you'll get a lot more control if you can do it with a variable HPF.
