Frequenzgang:22-25000Hz
* Test in Stereoplay 11/1993, top class 2
 
* Test in Audio 11/1993 top class, 66 points, 3 ears
 
  
According to the Stereoplay test report, the difference to the Level 5 lies in the Level 5's larger bass section. According to Stereoplay, very linear frequency response with low distortion values. Classification in the top class range (2?).
+
Impedanz: 4-8 Ohm
  
Level 5 received the next higher rating due to deeper, more powerful bass range.
+
Belastbarkeit :Nenn:160Watt,Musik:220Watt
  
My sound impression level 4: dynamic, analytical in all areas, transparent, due to large midrange driver effortless midrange reproduction with kick bass. Metal dome tweeter is not noticeable by aggressiveness / obtrusiveness despite powerful, well-faithful treble reproduction (linear according to Stereoplay).
+

Laut Stereoplay-Testbericht liegt der Unterschied zur Level 5 in der größeren Bassbestückung der Level 5.
 +
Laut Stereoplay sehr linearer Frequenzgang bei geringen Verzerrungswerten. Einstufung im Spitzenklassebereich (2?).
 +
 
 +
Level 5 erhielt die nächsthöhere Einstufung wegen tieferen pegelstärkeren Bassbereichs.
 +
 
 +
Mein Klangeindruck Level 4: Dynamisch, analytisch in allen Bereichen, durchsichtig, durch großen Mitteltöner mühelose Mittenwiedergabe mit Kickbass. Metallkalotte macht sich trotz kräftiger, gut getreuter Höhenwiedergabe (linear laut Stereoplay) nicht durch Agressivität/Aufdringlichkeit bemerkbar.
