  • Yamaha R-60 "rotating" guitar speaker

    These speaker cones are interesting.

    I’m pretty sure they had home stereo versions similar to those. I didn’t know they offered it as a guitar amp/speaker.

      Whoa. A home stereo that makes everything you play sound like it's played through an old Leslie?

        Here's a TA-120 guitar amp/speaker.

          It's a guitar speaker. So are they trying to create a type of sound for electric guitars with those speaker cones?

            I don't think those look like they will warble or rotate during operation. Their construction is of basic driver design.

                The rotating speaker portion from that link is interesting, too. They have a whole lot of creativity going on in that speaker.

                  Those are similar to Yamahas NS 20/30 speakers that came out in the mid 60's. They are basically DML/BMR speakers. If not mistaken Yamaha licensed it from Bertagni.

                  I wish P.E. would make a exciter as big as those Yamaha's.

                  You can see the acoustic damping material all around the inner cabinet, very similar to how GR research dampens there open baffle subs with there no rez foam.

                  I just use yoga mats as they are really cheap and works great.

                    It's like that automatic doughnut frying machine at the state fair.

                      That answers my question about the guitar version. The odd shaped speakers in the YouTube video obviously aren't intended to color the sound for an electric guitar.
