    Tweeters with short wires are the fastest right?

    So if I used one hundred tweeters in a ported box, how long should I make the port?
    Measure with mics, mark with chalk, cut with torch, grind to fit, sand to finish, paint to match.
    Updated Justin tuning sheet (Justin and Erica tuning companion for SMAART and REW)
    Do it for them.

    I have not personally had phase issues to speak of, but hopefully this will help those who have.
    I totally agree with JCsAudio and I have a 12" NOS Nguyen Dang, the cone is made like a butterfly wing with a detroit diesel powering it.

    So you can’t figure them out not you’ve never had them, slight difference, why post a troll post instead of asking an intelligent question?

    As near as I've ever seen was - SPEAKER BOUNDARY INTERFERENCE

    speakers wave hit obstacle and bounces back causing cancellations , carpeting ,padding ,dash mats ,help.

    [QUOTE]Speaker boundary interference response (SBIR for short) is a little known and poorly understood issue that is responsible for deep dips or “suckouts” in bass response below the transition frequency. SBIR is caused by the destructive interaction of the direct sound wave from the speaker and the reflected, indirect sound wave from a nearby boundary.[/QUOTE]

    I.E.
