Grade 1+ for quadral RHODIUM 5.1. set “This is how home cinema comes into your living room”

After the Lite magazine already hosted RHODIUM 500 and RHODIUM 200 as guests in an individual test, the surround set, comprising of both mentioned, RHODIUM 100 BASE, and QUBE 10 were analyzed as well. The result: Grade 1+ in the top class. We say “wow” and read excitedly the outcome of the testers: “The chosen Quadral Rhodium setup shows explicitly that the whole thing can be more than just the sum of its parts. Although I already knew what the Rhodium 500 was capable of in stereo mode, this 5.1. set – comprising of a floorstander 500, shelf speaker 200, Rhodium 100 Base, and the powerful Qube 10 active subwoofer – truly knocked me off. Therefore, the Quadral Rhodium surround set is a combination which is successfully in every detail and suitable for every living environment, hence first class manufactured loudspeakers to a completely reasonable price of 2800 Euro!”

Test: quadral RHODIUM 500

Living room rocker with design claim – grade 1.0 for the RHODIUM 500 Lite test

Lean, white, and all along convincing. This is how RHODIUM 500 presented itself in the test of online magazine Lite. Therefore the feedback of the test editorial: “You have to put close to 1200 Euro on the table for a pair of Rhodium 500, the top model of the newly revised quadral top class series. What you get is a duo of outstandingly manufactured and first class fitted floorstanders. A duo, that with an elegant, straight, and of an essentially shaped design convinces with excellent sound that you would hardly expect of these lean transducers. A, all in all very successful and fair calculated comprehensive package that definitely gets a recommendation from us. Who would like, can extend the friendly ambience appearing main speaker with a fitting center, shelf speakers, and a subwoofer to a complete surround set and this way, not only listen stereo, but also enjoy multi-channel in a capturing quality.“

Grade 1.0 (high class). Read the complete test of December 29, 2015.
