Slim, shapely and supple, our Signum series nestles into any living space and makes all hi-fi enthusiasts shiny eyes.

Polypropylen Membrane
Super-light membranes made of polypropylene ensure expanded spatial acoustics and deliver excellent sound enjoyment. The extra titanium coating provides additional reinforcement of the material and gives the speakers a particularly pure and clearly defined sound.

RiCom Tweeter
The RiCom Sigma, developed by Quadral, delivers distortion-free sound and a smart beat Ring Radiator. With its numerous, isolated indentations on the faceplate,it reliably reduces sound reflections on the front and transports the sound straight and without detours directly into the ear.

Balanced-Distribution-System
Extra large membrane surfaces and the latest quadral technology ensure that the balanced distribution system spreads the sound precisely and evenly. With the Signum 90 and Signum 70, the bass clearly gains in precision and depth and gives it an extremely rich timbre.

Processing
An elaborately manufactured, solid chassis in our Signum series ensures superior sound quality and impresses with its well-balanced design. The careful processing and classic shape guarantee a dynamic basic tone and a clean bass format.
Classic – Unrivalled

Design
Six different models in black and white form the baseline for our Signum series. With their classic shape and modest size, the loudspeakers fit into a wide variety of living styles and remain visually stylish in the background. The rounded edges ensure the balanced style. As a special highlight, we also serve all models exclusively in an exquisite walnut design for all noble wood lovers. Phase 1 and Phase 2 are also available in anthracite. Small but powerful – our Signum series presents itself in a delicate guise but with a lot of oomph.
Balance in perfection

Have you heard?
The balanced distribution system developed by Quadral was first used in our Signum series. The aim was to increase the precision of the sound with a controlled depth without loss of quality. Thanks to the extra large membrane and the new quadral technology, the power could be distributed evenly to the midrange and woofers, ushering in a new era of sound. Loudspeakers with a small chassis now also get an extra rich sound and are in no way inferior to large floor-standing loudspeakers.
Pure Harmony

The Signum Models
Tangible, differentiated sound with maximum power – that’s what our Signum series stands for. Equipped with the excellent, fine-resolution RiCom Sigma ring radiator, the sound converters make the air flicker and turn acoustics into a passion. Our hi-fi makers also created our titanium PP drivers for the mids and basses, and ensure homogeneous and impressive surround sound.
Harmonious variety

Potential
If you want top-class technology without compromise, you can’t get past Signum. Whether home cinema or hi-fi cave – clean surround sound and flawless bass make cineaste hearts beat faster and beathead heads nod. Consisting of various floor-standing loudspeakers, center and wall speakers, the series provides the all-round package for maximum listening pleasure with an unforgettable sound.







The Quadral Signum 70 proves what high optical and acoustic quality is possible in the middle class. The Signum 70 has an appealing design, a well-proportioned shape – and the sound really amazes us: it offers dynamics and bass power that we would hardly have believed this slim speaker capable of!
Our Signum 70 underwent the tough test of lite magazin. The test was conducted on February 13, 2022.
Top price/performance
Since the Signum 90 has complemented my existing setup of the center and rear speakers from the Signum series, the living room has become a large cinema and concert hall night after night. The sonorous sound inspires us every day. The beautiful, simple and chic design blends harmoniously into our living room. And is a real eye-catcher in the living room.
I have a set with the Signum 70 and Base, what can I say: simply great!
