... das ist ewig lange her, als man noch Mammuts mit Speeren erlegte...
soweit ich weiß waren es 2 Brüder Lansing, die sich irgendwie verfeindet haben.
Nachtrag: es ist etwas komplizierter, genaueres findet man hier:

und hier die jüngste Geschichte:
1998: Ailing Mark IV Audio Group is acquired and dismantled by Greenwich Street Capital Partners of New York. First, Altec is merged with elements of Electro-Voice as EVI Audio, but this quickly becomes a division of Telex Communications, also owned by Greenwich. Telex closes the Oklahoma factory and moves everything to its Michigan facility. Altec is sold off into pieces. Oklahoma engineer Bill Hanuschak and other former employees start Great Plains Audio for the maintenance of Altec speakers and continued production of compatible parts with tooling bought from the defunct Altec. Since Altec was started by ERPI engineers for the maintenance of WE gear, we have come full circle.
2000: Telex discontinues the Altec product line, except for a line of office ceiling speakers. The Altec Lansing brand name is sold to Altec Lansing Technologies, the new name of the whole Sparkomatic company. Mostly, the brand comes to identify a huge, and very successful, line of computer speaker systems (nothing remarkable engineering-wise, but I love mine).
2002: Altec Lansing Technologies re-opens the pro audio division as Altec Lansing Professional. Products include Duplex engine-type speakers for houses of worship, Duplex ceiling speakers, Mantaray horns, and (of course) the latest version of the 604 Duplex monitor speaker.
2003: Altec Lansing Technologies begins selling a legacy A7 Voice of the Theatre, using original plans, but with a 900-hz crossover, and an almost scary 200W power handling. $4300 (which includes shipping), and it's yours. You need two for stereo.
