    Vorab: Ich habe lange recherchiert und simuliert und gemessen. Daraus entstand eine 19L Bassreflex Box mit dem SB17MFC35-4 (und SB29RDNC-4). Leider ist der Klang des Lautsprechers eher flach und wenig dynamisch. Der SB17MFC35-4 braucht Pegel um zu klingen, also Eigenschaften, die man eigentlich nicht will. Kritisch ist auch der doppelte Höcker im Frequenzgang zwischen 4.4 und 6.5kHz, da sich diese im Summensignal wieder finden, es sei denn, man nimmt eine niedrige Übergangsfrequenz. Damit fehlen dann aber die oberen Mitten. In der Summe ist der SB18MFC35-4 ein Fehlgriff gewesen. Bessere Erfahrungen habe ich z.B. mit Dayton RS Serie gemacht (z.B RS125-4 in 9L) und würde ich für das nächste Projekt auch wieder nehmen. Ach so, der Hochtöner funktioniert, ist aber auch nicht besser als einer für 10€. Klingt langweilg ohne Glanz.

    This woofer in combination with the 26STAC tweeter, is an extreme good combination if the speaker units can be tamed regarding the filter - and I did that. The wow-effect is certainly present regarding 3 dimensional sound, voices/voicing, acoustical instruments and the system can even play bass. Bad recordings will be prevailed easily. My goodness, I am very surpriced how much sound quality that can be retreived from those speaker units - bravo SB Acoustics; designed here in Denmark :-)
