Dayton Audio RST28F-4 1-1/8" Reference Series Fabric Dome Tweeter 4 Ohm

 

The Dayton Audio RST28F-4 silk dome Reference Series tweeter offers exceptional efficiency from 1,400 Hz to 20,000 Hz with an extremely natural and dynamic sound. This unique 1-1/8" silk dome and a state-of-the-art Ferrofluid cooled motor system employs copper shorting rings to ensure that high frequency content is reproduced as transparently as possible, assuring studio-quality performance. RST28F-4 tweeters not only match the look and features of the RS woofers and midranges but also the clean, detailed, and uncolored sound that characterizes the entire series. These are just a few of the features that allow these tweeters to outperform some the most expensive audiophile high-frequency transducers.

Es sind sehr gute hochtöner, harmonischer homogener klang,
Ich habe sie natürlich ein wenig modifiziert um noch einen glatteren frequenzverlauf zu bekommen, das endresultat sind sehr sehr gut klingende hochtöner die höher preisigen Modellen locker das Wasser reichen können
