ESX Quantum Serie

Die in etwa handtellergroße 2-Kanal Mini-Endstufe QUANTUM QM-TWO sorgte gleich nach der Vorstellung bei ESX-Fans und Kennern der Car Hifi Szene für Verblüffung. Das kleine Powerhouse mit satten 240 Watt RMS Leistung wurde sofort als Geheimtipp gehandelt. Nachdem letztes Jahr die verbesserte V2-Version mit sagenhaften 300 W RMS Leistung das nochmals toppte, legt ESX nun mit zwei weiteren Modellen in der QM-Klasse nach: Für 4- Kanal Anwendungen steht ab sofort die klangstarke Endstufe QM-FOUR bereit, wer einen separaten Subwoofer antreiben möchte, kann jetzt zum neuen Monoblock QM-ONE greifen. Beide Powerriegel leisten satte 360 Watt RMS und sind optisch perfekt aufeinander abgestimmt. In allen Modellen kommt moderne und effiziente Class D Technologie zum Einsatz, kombiniert mit EPS, Top-Features und perfekten Klangeigenschaften. Der QM-ONE Monoblock ist nicht nur optisch der perfekte Spielpartner passend zur QM-FOUR. Wenn zusätzlich ein separater Woofer befeuert werden soll, ist sein Einsatzgebiet klar definiert. Mit satten 360 Watt RMS an 2 Ω ist für ausreichend Dampf gesorgt, sogar bequem per Basspegel-Fernbedienung einstellbar.

Perfect for espresso shots
This measuring cup is small, accurate, and very well made. The markings are clear and easy to read. The size is perfect for pulling double shots and measuring milk. The handle feels sturdy, and the design is clean and modern. Great quality for the price, works exactly as expected.

The combination of durable stainless steel, cool-touch walnut handle, dual pouring spouts, and internal gradations makes it both functional and elegant.
