    Our Tektonic friend has evidently changed his opinion on beryllium.

      Dunno. The overall effect may be interesting. All those tweeter lobes flying around may give music a Wurlitzer effect, or like it was played through an old Leslie.

          Well, I kind of question the 99dB @ 2.83V 12" bass drivers, too. May be best not to overanalyze what we see here...

            Yep- those are RSS subs, not pro-sound derived.

              Those are SB 6" (a great driver) And how in the heck do you run 15 tweeters? 1 most be getting more power than the others...
              Guess xmax's age.

              My guess: 15. His grammar is passable. His trolling is good.

                  Not necessarily.

                  The arrays of 7 above and below the center tweeter are basically set up as a "low tweeter" or "upper mid" and the single in the middle is the super tweeter. That's how they get the 4-way designation.

                    That would make more sense, I talked to this guy before and he claimed all the tweeters were operating at the same frequency also
                    if this is the case all tweeters would be operating out to 40K or whatever.

                      If they are all operating in the same range, then it isn't a 4-way like they claim.

                          Beryllium is cool now? Did the speed of sound change? Seems I missed a memo or two.

                            I have liberated plenty of magic smoke (we build power supplies that can deliver 130 amps per rail). Something that really should be
                            considered with Beryllium is the way sound propagates off it. These tweeters do sound great but they are completely different sounding
                            than the other SB tweets.

                              You missed several. Turned out, a beryllium violin sounded pretty sweet!
