Der SB Acoustics SB15CAC30 5" (13cm) Tiefmitteltöner mit Ceramic/Keramik Membran ist in einer 4 Ohm und 8 Ohm Variante verfügbar. Die ultraleichte und steife Membran wird von einem kräftigen Ferritmagnet angetrieben. Die Resonanzfrequenz um 30 Hz liegt weit außerhalb des Nutzbereiches, wodurch der Treiber im Nutzbereich äußerst linear spielt und sich optimal im 2-Wege Einsatz oder auch als reiner Mitteltöner einsetzen lässt. Die großzügig hinterlüftete Zentrierspinnne optimiert das rückwärtige Kompressionsverhalten auf ein Maximum und sorgt für zusätzliche Kühlung.

Merkmale : 

  • Belüftetes Aluminiumguss-Chassis für optimale Festigkeit und geringe Kompression
  • Geometrisch verstärkter Keramikkonus für optimalen Kolbenbetrieb und reduziertes Aufbrechen
  • Weiche, wenig dämpfende Gummisicke für verbessertes Einschwingverhalten
  • Nichtleitender Glasfaser-Schwingspulenträger für minimale Dämpfung
  • Verlängerte Kupferhülse am Polschuh für niedrige Induktivität und geringe Verzerrung
  • CCAW-Schwingspule für reduzierte bewegte Masse
  • Langlebige Silberdrähte
  • Belüfteter Polschuh für geringere Kompression

Malcolm speaks from the heart
"If George Washington didn't get independence for this country nonviolently, and if Patrick Henry didn't come up with a nonviolent statement, and you taught me to look upon them as patriots and heroes, then it's time for you to realize that I have studied your books well..." Malcolm X It is statements like this that make me love reading about Malcolm X. His intelligence, charisma and courage emanate from his words. He inspires, challenges and provokes his listeners to change their thinking. Not only does he challenge others, but he challenges himself to constantly analyze, to constantly evolve. Malcolm X Speaks is an excellent read, from cover to cover. If you want a good idea of where Malcolm was heading before his untimely death, this is the book.

The book was in excellent condition.
Format: Paperback
Truthfully, I can't find anything I dislike; the book arrived sooner than I anticipated. I have started reading the book (Malcolm X Speaks: Selected but have yet to finish. I am thinking about other books I will purchase in the future.

A beautiful mind
Malcom had the capacity to express his ideas in such an eloquent and smart way. This book is proof of that. I'm studying this great human being and now I consider this an essential book for anyone, any race, any place or gender that are looking to open their minds. Definitely a must read for any person.

... or sacred poem as my focus of concentration) I enjoy reading this book at bedtime for inspiration
Format: Paperback
Since I began practicing Passage Meditation (meditating on a prayer or sacred poem as my focus of concentration) I enjoy reading this book at bedtime for inspiration. I find that when certain prayers or poems resonate with me, stanzas from them will come to me during the day. Some of them I memorize quicker than others. I appreciate this book for having so many from so many traditions compiled and translated so beautifully. At the back of the book you can look them up by category, such as prayers for courage, or fear, etc. I am surprised at how many I have memorized, and how much they affect my thoughts throughout the day.
