    Danny Richie from GR Research gives out advice on New Record days channel.

    I've been intrigued by his open baffle subs and planars which is similar in concept to my DML panels.

    He doesn't look like I imagined.

    He's a member here at PETT but hasn't been very active.

      He is very active on A.C....I go there just to read his posts. IMO he seems really innovative, he even likes to upgrade other name brand commercial speakers. Most Industry participants wouldn't give any other product except there own the time of day.

        I remember two things that stand out for me on Danny. When Dennis Murphy was selling a small two way for a fund raiser for animals and ran out of tweeters Danny offered him the same model so he could continue his fund raiser. Danny also attended one of the first North Texas DIY events. For a guy selling his own line of speakers he was extremely kind with his input and feedback. Just a class act.

            Who remembers this classic thread?

              How can you not love that?

                In the early 2000's I used to frequent the Mad Board, and after a few years I got away from speaker building while finishing up my Navy career and riding dirt bikes for family recreation outside of San Diego. Good times.

                Many years later, I began seeing reference to Krutke on this site but have never noticed him actually around here. I'm guessing I missed all the drama years ago and he decided to steer clear of it all. Is this sort of correct?

                Which has me wondering, what ever happened to Zaph?

                  Zaph keeps his site open with a few designs. He produced a midwoofer and a set of designs using it, available elsewhere. This is about the only drama he ever was associated with that I'm aware of.

                      In part 2 Danny said you cant use 2 tweeters together as there is a suck out of frequencies. When I look at Bryston tower speakers they use two tweeters, is there a technique they use to prevent it?

                        Dang. That thread is downright toxic.

                          The crossover may possibly be modified for the second tweeter to change the frequency range that they both cover.

                            Maybe one of the tweeters isn't connected.

                              Yeah that's what I was thinking.
