Audio Physic – Codex


There is always a certain divergence between excellent music reproduction and interior design features. For a rich, deep bass and a solid foundation, loudspeakers require a certain cabinet volume. The CODEX successfully manages this tight-rope act, thanks to its intelligent cabinet architecture and variety of available finishes. Despite its volume, the four-way loudspeaker with its clear contours and slender baffle exudes an air of stylish elegance. Especially the high-gloss glass finishes, combined with bright colour tones, almost lends the loudspeakers an appearance of weightlessness.

Special attention was paid to the inner structure of the corpus, as only an extremely sturdy cabinet offers the prerequisite for a reproduction that is pure and true to detail. Numerous braces and extremely stiff elements, made of open-cell ceramic foam, lend the CODEX body superb stability, without noticeably reducing the interior volume. Thanks to the sandwich construction, featuring a permanently elastic intermediate layer, the cabinet is perfectly quiet. Thus, the acoustic impacts of the cabinet components themselves are effectively counteracted.

As with the AVANTI, the subwoofer on the CODEX is mounted in the interior of the cabinet, utilising an optimally matched chamber. The 10” long-throw chassis is extremely powerful and effortlessly transmits the lowest frequencies. From 100 Hertz on, it hands the baton over to a 7” chassis in the front of the cabinet. Here’s the benefit of this division of labour: The bass reproduction remains confident and controlled in any situation. What’s more, the CODEX offers considerably more latitude in terms of placement than traditionally designed loudspeakers, even close to a wall, they play with crisp structure and full torque.

The clarity in the lower octaves provides a cornerstone for exceptionally neutral and precise reproduction of mid and high frequencies. This is where the cutting-edge Hyper Holographic Cone Chassis, now in their third generation, come into play. The intelligent dual-basket construction of the chassis reduces any sound impacts due to micro vibrations to a conceivable minimum, as the chassis do not have any direct contact to the baffle of the loudspeaker. That is why the sound reproduction is not affected by any renegade resonance, so-called partial vibrations. In addition, the chassis have their own compartment in the corpus of the CODEX. This eliminates any interactions via the air volume in the loudspeaker. For maximum signal fidelity, the crossover network is distributed among several levels and equipped with first-rate components. The individual modules are placed next to each chassis.

The CODEX also shows meticulous detail in its connection terminal. Here, the loudspeaker cables are connected with high-end WBT nextgen™ pole pieces. The terminal is also mechanically decoupled from the loudspeaker cabinet. It is the sum of all these details that makes the CODEX a veritably mature loudspeaker – true to the AUDIO PHYSIC motto: No loss of fine detail.

Listening tip

Fat Freddy’s Drop | Dr. Boondigga | The Drop

With its music that almost defies traditional categories, the New Zealand combo, “Fat Freddy’s Drop”, has been celebrating stunning successes for several years now. On its second album, “Dr. Boondigga”, groove meets deceleration in a thoroughly habit-forming style. Soul, reggae, dub – the artists skilfully weave together a variety of genres, combining electric with acoustic instruments. At concerts, the musicians place great emphasis on a first-rate sound; the same goes for recordings. Truly powerful waves of bass enthral the interested listener from the beginning, making time go by in a flash. Whereas here, especially at higher volumes, many loudspeakers already reach their limits, the CODEX models show off their strengths. They meticulously differentiate the individual bass lines and offer the artists an authentic stage in all three dimensions. The CODEX loudspeakers transport the group’s pure joy of playing unfiltered right into the listening room.
