Du hast recht, Manfred!
War mir bisher unbekannt.
Ich lese gerade mal diesen Beitrag aus der Klipsch community

Also da betritt Magnat dann doch keinen neuen Weg, die Diyer waren da schon dran....
Na ja, war auch schon kommerziell....
Multiple-entry horn
A three-way multiple-entry horn in which each passband enters the same horn
In 1996, Ralph D. Heinz of Renkus-Heinz received a patent for a multiple-entry horn which incorporated multiple drivers for two bandpasses, high and mid, whose sound waves all exited into a single horn but at differing distances depending on the bandpass. It was marketed as the "CoEntrant" horn.[41] The mid- and high-frequency drivers in the Renkus-Heinz ST/STX product line both exited through a "Complex Conic" waveguide.[42] In the late 1990s, Thomas J. "Tom" Danley of Sound Physics Labs began working on a three-way multiple-entry horn, bringing the SPL-td1 to market in 2000.[43] The design used seven drivers, with one high frequency driver at the horn's throat, four mid-frequency drivers near the throat and two low frequency drivers ported closer to the horn mouth. In 2001, Tom Danley began developing the "Unity" horn for Yorkville Sound, patenting the improvement in 2002.[44] Following the 2003 release of Yorkville's Unity line,[45] Danley formed Danley Sound Labs and developed a significant improvement over the SPL-td1 called the "Synergy" horn, yielding substantially better phase and magnitude response along with smoother polar pattern. The synergy horn design delivered greater power output from a smaller loudspeaker enclosure.[46] Because the design retains pattern control through its crossover regions and over a large range of its total bandwidth, and because the acoustic center of the design is near the rear of the enclosure, it is more easily combined in arrays for public address applications.[47

Das originale Patent ist wohl gerade ausgelaufen, da kann Magnat einsteigen....
