Midwest Audio Fest

It’s that time audio enthusiasts! Registration for the 2019 Speaker Design Competition is now open! Visit midwestaudiofest.com for details and to list your speaker project. We are excited to see all returning participants, and look forward to meeting some new designers this year, as well! Be sure your plans include a visit to the Parts Express Tent Sale for the lowest prices of the year, and the Audio Swap Meet where you can buy and trade with other audio fans. We hope to see you this summer! Vivian and Jill

    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?
