    Hi Carl.
    Are you up for a bit of challenge? I am thinking of a shootout for the next NY DIY. Looking to build a 5.5" Satori/Viawave combo. Would be in the same weight category as your Intimates.
    Let me know if you are game.

    Now that I've learned to use Waslo's xsim software, I modeled the Intimates and added a screenshot of the crossover and FR plots.

    Carl demo'd these for me on Friday while I was there dropping off a pair of OLA woofers for him to work his magic on.
    His Intimates are beautiful and they sound amazing!!
    When he removed the grille, I saw a much smaller bass driver than I was hearing!
    A wonderful open sound!
    VERY nice work, Carl!!

    Eric-
    Mouser has the Arcol resistors like that, as well as the Vishay/Dales you are likely referring to. The Arcols are cheaper. I see why you use cell pics now. ;)

    Paul-
    Using the print-screen method, you can't just frame in what you want, correct? This way I don't have to move it into a photo editor, or anything like that. Just snap and save, even for Flash objects!

    Sorry for the Hijack, Carl!

    I ended up with the 20W Mundorfs because of the convenience of using the wooden dowel and knowing my volume level would not be very great. The SFE was spec'd to a much higher wattage level (along with a very high price ;)) and thus the 50 W resistor noted in the article.
    Just to be safe, I did buy some NTE 50 W 1% resistors, but haven't seen the need to use them yet.

    Sorry, the computer I test with isn't hooked to the Internet. So I cell picture it, email that straight to Photbucket, then post here or wherever. As for the heat of the resistor, dunno, for measurement/protoing I use an l- pad. The article states to use a 50 Watt resistor once you figure out what size resistor you need.

    I use screenprint 32 v3. However, it requires my Win V7 64 bit system to re-align itself.

    Does anybody know of Win V7 screen print compatible free SW? MWsnap evidently isn't either from what I gathered from their website. Their SW goes as high as XP.

    YOu don't even need to get that fancy. Just meet my friends <ALT+PrintScrn> and <CTRL+PrintScrn>. Copies to clipboard.

    When I was at the bread board stage, I wanted to test the potential for resistor heating after reading about the SFE heat sink. I found the tweeter series resistor got quite hot to the touch playing a signal at loud volume for a minute or two. That led to the vent cooling idea.

    Obviously, the resistor heating is a sign of efficiency issues. My speakers test in the 84-85 dB/2.83V @ 1M range. As always, speaker design is a series of compromises. I gave up efficiency for simplicity and performance.

    I did the AR capacitorless design, sounds good!
    I'll scope the impedance out tonight...

    Measure the impedance, Bud.
    I fear you're dippng into bad territory.

    Which xo did you use? How was the sound?
