ESX Quantum Serie

Für gute Subwoofer-Systeme werden immer kräftige Zusatz-Verstärker benötigt. Wem die Installation eines externen Verstärkers zu aufwendig ist oder keinen Platz hat, greift zu Aktivvarianten, die bereits werksseitig verbaute Verstärker haben. Doch Vorsicht, oft werden aus Kostengründen - auf den ersten Blick für Laien nur schwer erkennbar - leistungsmäßig eher schwache oder veraltete analoge Endstufen eingebaut. Manches Mal sind sogar einfachste 12 Volt Brückenchips zu finden, die nicht mehr leisten als einfache Autoradios. ESX geht hier einen anderen Weg und integriert hoch moderne Class D Verstärker-Module, die bis zu 400 Watt/RMS Ausgangsleistung mobilisieren können. So bestückt liefern die sehr kompakten QUANTUM QXB Aktiv-Subwoofer-Systeme extrem hohe Leistungen und Basspegel.

ESX verwendet dafür hochwertige und preisgekrönte POWER4 Aktivmodule, welche mit bis zu 84% Wirkungsgrad auch besonders effizient sind. Dank modernster Class D Schaltung und EPS PRO sind diese Module sogar für den Anschluss an ganz moderne Fahrzeuge vorbereitet. Mit der beiliegenden Kabel-Fernbedienung lassen sich die Bässe vom Fahrersitz aus einstellen.

Auch in die Aktiv-Varianten der QUANTUM QXB Subwoofer-Systeme hat ESX jeweils 4 Montagefüße beigepackt, die bei Bedarf auf die Frontseite geschraubt werden. So können beide Modelle ohne großen Aufwand in „Downfire-Subs“ konvertiert werden. Diese mit dem Woofer nach unten abstrahlenden Boxen eignen sich besonders gut z.B. für die Installation in doppelten Kofferraumböden.

A Revolution of Faith and Freedom
Format: Hardcover
Eric Metaxas’s Revolution: The Birth of the Greatest Nation in the History of the World presents the American founding as far more than a political dispute over taxes or power—it is portrayed as an epic struggle between liberty and tyranny, virtue and corruption, good and evil. Through vivid storytelling and rich historical detail, Metaxas casts the Revolutionary era as a moral drama in which ordinary men were called to extraordinary courage against overwhelming odds in their fight for freedom. The book compellingly shows how patriots like Samuel Adams, Patrick Henry, John Adams, Abigail Adams, Benjamin Rush, James Otis, Henry Knox, Paul Revere, John Hancock, Thomas Paine, George Washington, Martha Washington, and others, understood the conflict not merely as resistance to British overreach, but as a defense of God-given liberty against arbitrary, and often brutal, power. A particularly striking theme throughout the book is the Founding Fathers’ deep reliance on Divine Providence. Metaxas highlights how many believed that human rights flowed not from kings or governments, but from God Himself, and that the outcome of the Revolution ultimately rested in His hands. Prayer, biblical conviction, and appeals to Providence are woven into the narrative, reminding readers that the Founders often saw themselves as instruments in a larger story unfolding under God’s sovereign care. Indeed, Providence often revealed His hand in altering the weather and divinely guiding the patriots as they fought the British forces. The result is a sweeping and engaging account of America’s birth that frames the Revolution as both a historical and spiritual struggle, fought with courage, conviction, virtue, and faith.

A New Classic
Format: Kindle
I pre-ordered, so I was able to get the PDF and start reading early. Of all the books I own on the American Revolution, I think this one stands to become my "go to." It is encyclopedic in scope, but deftly avoids becoming a drudgery or a slog through a mire of textbook facts. Somehow, Eric has managed to include a great deal of detail without losing any of the drama. It’s the story that rises to the fore in a gripping tale that just happens to be true (and much more than that, is our heritage). All the trademark “Metaxas” hallmarks are here: judiciously placed humor and lightheartedness that never descends into silliness, seriousness that somehow never lacks in winsomeness, depth that never smothers. He manages to portray both the soberness that the subject deserves without losing the hopefulness that the story of the Revolution should inspire in us. And along the way, you’ll find yourself better understanding what “went down” and (just as importantly) what it means to you today. Excellent work. If you think another history book on the American Revolution cannot inspire you or keep your attention, this one is up to the challenge.

The History Teacher I Always Wished For
Format: Hardcover
With his trademark wit and his eye for those wonderfully absurd details that most historians tend to overlook, Metaxas drew me deeply into the story. I found myself laughing out loud one moment and profoundly moved the next. The tiny anecdotes and humorous asides were not distractions at all — they were precisely what made these towering figures suddenly feel human and unforgettable. Eric makes these historical figures flesh-and-blood again. He brings both heroes and villains vividly to life in a way that makes the drama of America’s birth feel immediate, thrilling, and deeply personal. In short, Eric Metaxas is the history teacher I always wished I had. At 600 pages, this book reads with the ease and momentum of a paperback novel, yet carries extraordinary depth and scholarship. In the end, I came away with a renewed love for American history and a deeper gratitude for the souls who made this great country possible.
