      The link is bad for some reason, but copy / paste the text into your address bar and you're golden.

          Ha - was about to dump the raw HTML code the browser winds up parsing.

          There was a ton of extra markup in the ref. Musta been how / where you copied it from initially?

          HTML Code:
          <a href="http://techtalk.parts-express.com/url?sa=t&amp;rct=j&amp;q=&amp;esrc=s&amp;source=web&amp;cd=1&amp;cad=rja&amp;uact=8&amp;ved=2ahUKEwiJqbnv14jeAhUJnawKHTTSAh8QFjAAegQICBAB&amp;url=https%3A%2F%2Famcoustics.com%2Ftools%2Famroc&amp;usg=AOvVaw28af0llZ0hUGDfFb05BsED" target="_blank">https://amcoustics.com/tools/amroc</a>
          Nice applets. Book marked.
          Feel free to rip my assumptions apart when wrong, or fix if close.

          Passive Radiators:
          All PR(s) Vd must at-least double all woofer(s) Vd. Calc = Sd x Xmax to get Vd for all PR(s) and all woofer(s). If all PR(s) Vd at-least double all woofer(s) Vd they'll work.
          For woofer(s) with large Xmax vs Sd, all PR(s) with Xmax at-least double all woofer(s) Xmax will work.
          A PR max weight is said to be its Mms x3

          PR Systems - tight focus with key parameters.
          PR Speaker Design - thorough coverage.

            Hi Sydney

            thanks for posting my room mode calculator!
            I'm the author of amroc, the second calculator you mentioned and I'd be happy to hear what makes you favor the bobgolds calculator over amroc.

            Feel free to criticize freely ;)

              Actually I didn't state a preference, but rather that I have used bobgolds for some time and very recently found your fine work.
              There are numerous Calculators on-line - these were perhaps the best I found to date.
              There are differences - Amroc has functions that are useful.
              Afraid I don't yet have a detailed compare/contrast evaluation at this point ( not enough "run time" yet ) .
              Perhaps other will provide feedback as well.
