Project Description


The all new successor of the worldwide praised TIDAL Piano Diacera has all the hallmarks of a Tidal. Supreme neutrality and transparency. A complete invisibility of cabinet and a huge holographic soundstage.

The new Piano is also an ingeniously flexible loudspeaker. It has a true 2 way monitor mode for smaller rooms and then a dual woofer ‘linear 2.5’ mode for medium rooms. Finally in ‘gained 2.5’ way mode, the Piano plays with gained bass for large rooms or simply more bass in small and medium rooms. Similarly the tweeter has a straight linear mode and then a +2db gain setting to suit the damping of your particular room. All of these settings are extremely subtle and well within Tidals’s linear sounding philosophy.

Now available in Tidals special VELVETEC™ matt finish which ensures a much shorter lead and delivery time.





The cabinet of the TIDAL Piano is made out of TIDAL’s proprietary cabinet material TIRADUR. This cabinet material does combines the rigidity of hard materials such as metal with the resonance absorbing behavior of softer materials such as wooden materials like MDF.
It is the only advanced cabinet material allowing to use organic surfaces such as our famous polished veneers, as well as true polyester piano lacquer. So when you see the Piano in the most beautiful pyramided mahogany, ebony macassar or our shiny black piano finish – don’t make the mistake to think the cabinet is out of wooden materials or MDF. And yes, this is why such a modest sized speaker weighs a whopping 65 Kg (143 lbs.).


TIDAL Piano or TIDAL Piano Diacera – the visually most obvious difference is the 30mm (1.2″) tweeter. In the TIDAL Piano it is a graphite coated ceramic tweeter. Of course there is more than that, since we do design for every tweeter/midrange combination the perfect passive crossover layout, and not just simply switch/offer two different tweeters.

This particular tweeter does not lack of any excellence at all and offers the entry into the world of TIDAL loudspeakers. It is housed in the very same massive stainless steel part such as the diamond version and therefor free of compromises, such as every detail of a TIDAL loudspeaker.


The TIDAL Contriva has an Accuton 30mm pure diamond diaphragm tweeter. Not only it is the biggest diamond tweeter in the world, TIDAL also was the very first company at all using a 30mm diamond tweeter. While the driver itself offers already terrific qualities and is being installed in a massive housing out of polished stainless steel for optimized resonance control – only in combination with our unique TIDAL crossovers this driver can perform in way what we have become famous for.

Maybe interesting to know on a side note: this very same diamond tweeter technology is being used also in the worlds most exclusive car, the Bugatti Chiron.


TIDAL’s exclusive BCC driver technology is the result of the Accuton TIDAL cooperation for more than a decade and are to find only in TIDAL speakers. The diaphragm itself is a special coated black ceramic diaphragm and uses a “short coil / long gap” neodymium motor perfectly designed for the hermetically sealed and asymmetrical designed midrange chamber of the Contriva.
Embedded in a special shaped ring out of hand polished massive stainless steel to avoid reflections form the protection grill, needless to say that this driver does guarantee absolutely no compromise for the performance and reliability.


Like all TIDAL loudspeakers the Piano has our unique pure silver binding posts. The complex construction out of a fibre-reinforced polymeric material avoids any inductive electromagnetic field and as conductor we use pure silver to guarantee the most little resistance and no loss nor change of the incoming music signal.

The massive metal feel of the knobs itself is coming from that it is hand polished and structured aluminum over an isolating part out of another polymer. The Piano does allow the adjustment to play in small, medium or bigger rooms. It is extremely flexible to adjust and allows to run it in situations where the choice is usually a 2-way monitor, to avoid over powering the room. Furthermore one can adjust the filtercurve of the tweeter as well.


Mounted in a hermetically shielded chamber: pure copper foil capacitors, coils of the same caliber, silver-carbon resistors – only the finest components with proven long time stability are used for our crossovers. Unfortunately, these components are also the most expensive ones and are custom-built for TIDAL. Whether any part must be that expensive is a meaningless question and, for one thing, not one that should arise from budgetary restraints. Only the final result is what counts to us and considerations of cost do not enter into the equation.

Our guiding principle is to present our customers with the highest possible degree of reality in musical rendition. Anything less is already amply available but does not meet TIDAL’s demands. That is why literally every component is scrutinously evaluated and selected on the understanding that it has be the one without alternative for its specific purpose. So for example even our smallest speaker is equipped with massive DUELUND copper capacitors.


As option the Piano could be equipped with 4 massive aluminum isolation feet per speaker. Each of it is milled out of a massive block of aluminum and available in two  versions: hand polished silver and covered with a special coating avoiding any kind of oxidation or with a black structured hard coating. Just slide the picture at the right side to see: one could mount the speakers in a parallel or sloped position.  Needless to say that even these parts are 100% made in Germany.


TIDAL’s proprietary finish VELVETEC™ is a special choice for the Piano series exclusively. VELVETEC™ is an unique silky-matt, both light absorbing/reflecting ceramic particle lacquer. It does allow us to offer all merits of a TIDAL speaker first time within a shorter waiting time – simply because the drying time is factor 30 smaller.

Though it is a special and exclusive enough to be offered from us a true TIDAL finish. VELVETEC™ is non fading in color nor will it not bleach over time or starting to get yellowish, especially in white. It is also durable and not delicate to finger prints. Available in summit white and jet black, and as limited edition in sonoma orange and amethyst, the contrast of all the polished stainless steel details and VELVETEC™ itself makes it the perfect choice for both contemporary and classic interior designs.
