    Question JBL room mode calculator

    Does anyone have a link to the JBL room mode calculator I seemed to have lost the link on my other pc and can’t remember the precise key word name I’ve done a search here and drawn a blank here.

    It moves

    Courtesy of 'Knightfly' from another forum:


    Harman has redone their site, and of course nothing works anymore
    http://www.harman.com/about_harman/technology_leadership.aspx
    Then click on "White papers" -

    This brings you to a page where you can either read their papers, or click on "Calculators" - you want "Calculators".

    Then, click on "Read" - it will bring you to a page where you can download either of the two calculators offered, one of which is the mode calc.

    Cheers...

    Did a search on Dan Siefert and found this one if you can open it. Think it requires Excel

    Sorry mate. I did some more research. Looks like it is a Microsoft Excel requirement. Couple of references here.

    For Valentin

    Hello again Valentin. Here's a link to a thread you may find interesting. It's a clever application using the JBL calculator for ballparking speaker/listener placement. I say 'ballparking' because some rooms don't measure up quite as predicted. Both frequency and location change from calculated to actual for a bunch of reasons. You could find the nulls/peaks in your room with a SPL meter and freq generator and adjust your plot accordingly...

    Cheers

    Thanks mate for the above link. I just left a message over there see if this works out in getting a direct link to the software program. I can’t understand why Harman would want to make it so difficult in finding a program software to help users solve and plot out the room where these room mode bugs are, oh well its not a perfect world is it.

    Okay I’ve inputted the size of the room and it’s done the calculations. So how do I deal with this issue with minimal fuss?

    I highlighted the data which had the figures and the darn thing was presented horizontally instead of vertically.
