Experience the live atmosphere of a concert to the full. Let yourself be moved by music as true as when it was first played. The PLATINUM 820 offers true-to-life music reproduction even with relatively small amplifiers. With a balanced overall composition, the interplay of explosive bass dynamism from two woofers in the reflex cabinets, precisely defined midrange frequencies and finely honed trebles from quadral's filigre titanium dome combine to produce undistorted listening with a feeling of space.

Whether it's the runaway power of an orchestral performance or the subtle timbre of a solo instrument, PLATINUM 620 transports you into the mood of a live concert. The performers are housed in separate cabinet chambers: a woofer for authentic, powerful bass notes and a high-output low/midrange for the entire frequency spectrum of the tonic scale. The titanium dome scatters its brilliant trebles over the other sounds.

This loudspeaker has a discreet appearance which belies its powerful performance. It gets the best out of your amplifier: lively reproduction with a spacious sound impression. A stroke of technical finesse enables it to achieve this: bass reflex with ACW (air coupled woofer) diaphragm for clean, deep bass notes. The realistic impression of space is made complete thanks to the fine counterpoint with the treble range that also offers excellent performance.

Many high-end hi-fi aficionados believe that two-way systems cannot be bettered. This confirms their view. The impressive duo of the quadral aluminium bass diaphragm and titanium dome tweeter pushes speaker performance to the limits of the audible range. They paint pictures in sound with draughtsman-like precision – powerfully and with precise contours. For hi-fi pleasure or as additional loudspeakers in a surround system. The entire PLATINUM range gets top marks for style. Even the small ones prove this point - on the shelf or on stands.

Listeners have a wide range of requirements. But there's always one speaker which answers the call: the compact PLATINUM 120 bookshelf unit. Its talents range from attention-grabbing sound through to sensitive melodies. It's a confident performer whether unaccompanied as a hi-fi speaker or with powerful subwoofer support. It can also be used as the front and rear speakers in a surround set. Three sources of sound are responsible for its high-performance reproduction qualities: woofer, bass reflex tunnel and titanium dome. The finest technology in the smallest cabinet - but unalloyed PLATINUM nevertheless. (DESIGNSTATIV B optional)

This 3-way center loudspeaker delivers a bravura performance in the surround ensemble, giving clearly accentuated dialogue. There is a phase correction function built into the crossover network to ensure that the spoken word reaches the listener in synchronisation with the pictures. As a result, it compensates for acoustic pressure losses within the listening area and endows every syllable with meaning. This makes the PLATINUM BASE very tolerant with regard to the listening position; even people sitting to one side remain in the heart of the action.
