    Im building a set of speakers for my electronics class and have to build/design the speakers. I have just ordered the dayton silk dome tweeter

    (http://www.partsexpress.com/pe/pshow...=275-070&DID=7)

    and the 6-1/2 Woofer

    (http://www.partsexpress.com/pe/showd..._ID=7769&DID=7).

    I havn't touched the cabinet side of things yet, but wanted to get confirmation that my crossover schematic will indeed work.

    Its a 2nd Order Linkwitz-Riley Alignment (12dB/ocatve) w/ zobel circuit for the woofer and a Series notch and am L-pad for the tweeter.

    High Pass: 5.17uF & 600uH
    Low Pass: 4.65uF & 670uH
    Zobel(for Woofer): 31uF & 7.5Ohm
    Series Notch(for Tweeter): 18uF & 1.5mH & 10Ohm
    L-Pad(for Tweeter): 1.1Ohm(Series) & 25.5Ohm(Parallel)

    Tweeter wired opposite polarity of Woofer.

    If there are any incorrect values or if you beleive I need to add something or take something away, please feel free to give me your opinion.

    Thanks Alot

    Adam

    Did you base your values on textbook equations? Filter design must be based on actual SPL and impedance measurements of the drivers in their enclosures. I wouldn't recommend you go through the trial and error process of tweaking the component values, especially since this is for an electronics class -- it won't look good on your report IMO.

    SpeakerWorkshop is a freeware measurement and simulation software, which you could use for your project.


    Good luck with your work!

    Values were calculated using "Passive Crossover Design Excel Program", I used the CLIO respons graphs and T/S parameters I found at PE.com.

    Thanks for the program,
