    PURELY FOR GAMING

    Has anyone added tweeters to the Z5500?

    Adding 5 x tweeter for each speaker

    http://www.theloudspeakerkit.com/dayton-audio-nd16fa-6-5-8-neodymium-dome-tweeter

    I need to add a capacitor to each speaker, but do not know which type.

    Can anyone help?

    Any hints, etc

    7.2 system at home runs 2 x anthony gallo subs and 7 x A'Diva, so the Logitech is ONLY for the PC to play games on.

    I have Audio Technica headphones too, but like the 5.1 for games

    To add extra treble for each speaker.

    I thought you'd want to add midrange more than treble for Z5500's?

    Adding highs is what they seem to lack.

    Why do you think the midrange is lacking?

    Am I totally off track?

    Personally for gaming use I wouldn't really bother to upgrade it.

    Personally I put audiophile in the same mental illness category as non-caeliac gluten free nutcases.

    Don't follow audiophile sites.

    I would go for midrange over highs on my z-5500's too. They're tiny speakers, which I'd argue lack depth in the midrange over treble. Sound is so subjective though. If you feel they lack treble, do whatever you wish, but don't mod it just because someone said so or because it looks cool.

    Might even be able to get away with some EQ if you just want a little more high end.

    Adding tweeters to those Logitech's is a waste of time, effort and money, go with an EQ or preamp with tone controls.

    Did I also forget to mention that most of the folks posting on head-fi are morons?

    When I side by side the z5500's with "proper" speakers I always find the treble lacking, I'd be interested in a simple tweeter mod too. We'd all love 6" drivers in front of us but for many there just isn't space, the z5500's full range drivers do a decent job considering their diminutive size.

    tweeters delivered.

    I need help working out how to connect and what (capacitor?) to connect inline.

    Anyone?

    I'll bite. What you are looking to build is a passive highpass crossover.

    Your one cap description is a 1st order crossover and will attenuate frequencies below the crossover point by 6db/octave.

    Use this calculator:
    http://www.the12volt.com/caraudio/crosscalc.asp

    In a nutshell and completely simplifying crossover design so.....

    1) Determine what freq you want to high pass at. Going off spec sheet anything above 3500Hz will do. Ideally you want to find out\measure the frequency where the z5500 starts to attenuate at and have the additional tweeters pick up\reinforce from there.
    2) Determine the impedance of the tweeters (6ohm for the daytons)
    3) Plug values into calculator
    4) Find closest non polarised metallised film capacitor closest to the calculated value with a high enough voltage to handle the power you will be presenting to the tweeter. Pretty sure most you will find will be at xxxVolts range and should be plenty for the 10W of the daytons.
    5) Wire it in. Capacitor in series on the + lead of tweeter. Then the tweeter system wiring in parallel with the existing satellite speaker wiring.
    6) Hope that the amplifier will handle the 3.7ohm load you will now present to each channel. Also hope that there is no inbuilt EQ\DSP on that Z-5500 that is screwing with the high frequencies.
    7) Profit or Loss.

    Example:
    5.3uF capacitor will get you a 1st order highpass crossover that starts to attenuate frequencies to the tweeters below 5000Hz. A 7.5uF capacitor will be at 3500Hz.

    Good luck!

    Oh yeah someone measured the frequency response on these already, maybe 3500Hz is a better place to start experimenting at. http://www.audioholics.com/soundbar.../logitech-z-5500-sound-quality-and-conclusion

    Just did the first speaker.

    It IS worth it.

    If anything these speakers lack bass. :wired:

    I do love my z5500's.

    Oh wow, super kermit actually went ahead and did it. I hope it was worth the effort. Pics would be cool.

    In regards to adding midrange

    Is there a speaker to do this?

    Yes,

    You throw Logitech shit in the bin and buy decent speakers.

    Z5500 are okay, but you cant polish a turd.
