in the test




Sound from all sides!

Large multi-channel test at AREA DVD: 10 quadral loudspeakers lined up to create the perfect surround sound. In detail: 2x quadral PLATINUM M40, 2x PLATINUM M20, 1x PLATINUM M10 BASE, 1x QUBE 12 and 4x the new effect-stage PHASE A10. Together, the ensemble won the title "price class reference". The bottom line of the test project: multi-channel experts from Hanover: The Quadral 5.1.4-set pleased us in the test with a far above-average performance. The spatial effect with four tower modules is gigantic; one feels enveloped by all sides and in all dimensions of sound. The quadral ensemble converts very well, what “immersive sound” wants to achieve. All components are level-resistant. The QUBE 12 active subwoofer impresses furthermore with its impressive design. The built-in output stage with a full 500 watt sine-wave power fits into the first-class overall picture of this multi-channel system. Thanks to the RiCom V tweeter, the Platinum components included in the set, play up to 50 kHz, making them ideal for high-definition audio media. The processing is excellent, even in the detail we do not find any defects. The top firing modules, phase A10, however, are technically - with a broadband chassis - very simple. Here the competition (KEF, ELAC TS3030) puts in more effort. With the 5.1.4 set of Platinum M, Phase A10 and QUBE12, quadral delivers an impressive statement for modern multi-channel sound"

„Plain speaking

The Quadral Platinum M40 is not stingy when it comes to its advantages. The ample and innovative configuration gives it a powerful sound, which does not lose any of its impressiveness at high volumes. This guarantees overall neutral tonal tuning with particularly non-stressful and therefore relaxed musical enjoyment. This speaker is recommended for use in medium sized and large lounges and you will be enchanted by the supreme bass power, punchy mid-tones and high definition high-tones.
