Römer-ESL-Horn MkIV - Thinking Physics to its End
Excerpt from the constructions drawings of the latest MKIV version of the Römer ESL Horn, Harmonic combination of impulse-true Bass driver and ESL. The lf-horn is a hypex based construction with impedance-matching and tuned with reactance anulling
Die Faltung ist eine Hypex-Tractrix Symbiose mit Entwicklungsschwerpunkt auf dem Impulsverhalten und Linearität des Amplitudengangs. Der synergetische Effekt besteht in einer Nutzung des maximalen Strahlungswiderstandes über einen möglichst großen Frequenzbereich.
Die Prinzipien des Reactance-Annulling und Impedance-Matching nach Plach wurden in diese Entwicklung integriert. Die untere Grenzfrequenz der Hornparameter wurde deshalb nicht nach unten überzogen. so dass über den benutzbaren Horn-Wirkungsbereich auch ein echter Strahlungswiderstand effektiv wirksam wird.
