Audio Physic TEMPO 25 White Gloss (ÇİFT)

Tempo 25

Over the years, the TEMPO has turned into a classic in its own right, achieving international acclaim among the more affordable high-end loudspeakers. At the same time, it has become the very embodiment of all the great sound virtues that Audio Physic stands for. And that was all the reason we needed to further improve this loudspeaker to celebrate Audio Physic’s 25th anniversary. The result, a limited special edition named TEMPO 25, is loaded with a HHCM midrange driver and a HHCT II tweeter, both at the pinnacle of driver technology. It is the first time that a loudspeaker in this price range is equipped with these drivers, borrowed from the CARDEAS flagship, featuring an elegant sleek cabinet and capable of delivering a pure, powerful and precise sound in small and large rooms.

Active Cone Damping

Active Cone Damping (ACD) was first developed and implemented by Audio Physic in order to avoid resonances associated with metal cones. A silicone/rubber ring is mounted on the outer ring of the cone where it directly applies pressure on the cone. This is a highly effective means to eliminating the otherwise unavoidable ringing and therefore removes the metallic sound.

Push Push

Audio Physic's three-way and three-and-a-half way loudspeakers are equipped with side firing woofers. Even when applying large-diameter cones, our loudspeakers keep a narrow baffle design which allows for the superb spatial imaging Audio Physic loudspeakers absolutely excel at. Compared to the configuration often used nowadays where the woofers are mounted only on one side, Audio Physic prefers to arrange them on both sides of the cabinet. The drivers are operating in phase (all woofer cones move simultaneously in the same direction, either inwards or outwards). Forces acting on the cabinet are nearly cancelled out with this effective – so called push-push configuration – and precise, low-resonance sound reproduction is achieved. However, the push-push configuration must not be confused with the push-pull principle commonly used for power amplifiers.

Vibration Control Terminal :: VCT

A negative impact from unwanted resonances on the transmission of signals can be detected at each point of the reproduction chain. The use of high-quality and stable rack systems as well as special stands, feet or bases may often yield astonishing results.

However, no attention was paid to another important path of mechanical mischief-makers. Cables – necessary to transmit the signal – not only carry electrical signals, unfortunately they also carry mechanical energy which moves at its strongest in the opposite direction to the signal. Therefore, vibrations picked up and measured on a loudspeaker cabinet can be followed back to the source of the signal. Audio Physic has developed the Vibration Control Terminal in order to eliminate such unwanted vibrations. The massive aluminium construction is additionally damped and fitted with a neoprene gasket for elastic suspension ensuring that the binding posts are effectively decoupled from the cabinet.

Hyper-Holographic Cone Midrange Driver (HHCM)

Hard shell – soft core: an awesome midrange driver and exclusive design by Audio Physic!

It has been commonplace for many years to manufacture driver baskets consisting either of plastic or metal. However there is a well-known German proverb saying that double stitching lasts longer.

We took this to heart, doubled our efforts and designed the hyper-holographic cone midrange driver, HHCM in short, a novel basket construction using a combination of aluminium and plastic. Aluminium is stiff and conducts heat better than plastic material which, in turn, allows for a much higher internal damping. Both characteristics are important in loudspeaker manufacturing. Provided that the two materials are efficiently combined, their properties complement each other in such a way that damping of resonances is perfectly coupled with mechanical and thermal stability.

The two materials are used where they do their best in what they are best at doing. Moving parts such as the diaphragm, the surround, the centering device and the voice coil are held in proper alignment by a plastic inside basket designed to achieve a maximum degree of damping inside (marked in red in the illustration). The powerful neodymium magnet is encased in an outside basket made of die-cast aluminium.

Let us look at the advantages: the generated heat is efficiently dissipated by extensive cooling fins whereas remaining vibrations are transmitted to the mounting ring via slim stiff bridges.

Such a double-basket construction makes a lot of sense. Basket and cabinet resonances are effectively kept away from the driver diaphragm while at the same time the thermal behaviour of the midrange driver significantly improves.

Special attention is also given to the aluminium diaphragm itself which takes full advantage of Active Cone Damping II implemented to avoid ringing resonances frequently associated with stiff diaphragms. A U-shaped elastic ring is designed to fit snugly around the rim of the cone, causing the diaphragm to tighten. Therefore, resonances having an adverse effect on the sound quality can be prevented right from the start.

All these measures have only one goal in mind: to achieve a perfect marriage of ultimate resolution performance and absolute freedom from coloration.

In addition to achieving outstanding measurement results, the HHCM truly lives up to its name, reaching a superior subjective level of reproduction quality.

Never before has music been reproduced with such holographic quality!
