The French brand Diptyque Audio had fun with this Reference panel presented at the High End in Munich. Indeed, it adopts a much more luxurious and robust look than the brand’s previous speakers as well as ae patented technology crossed push-pull, while maintaining a deeply audiophile design.
Audiophiles who regularly listen to baffle speakers or acoustic panels know the song. The loudspeakers use a thin membrane, here in mylar 12 micrometers thick, traversed by a thin conductor and set in motion by magnets (we will come back to this). We find, in short, somewhat the same acoustic principles and the same mechanisms on ribbon tweeters and on headphones with magnetic planar technology. Attention, this technology should not be confused with electrostatic technology, for which, often, the entire membrane is conductive and moves between two grids electrostatically charged by a power supply.
To return to isodynamic acoustic panels, they can offer exceptional performance in the midrange and at the timbre level, especially for listening to acoustic music. However, for bass, it’s a different story. Acoustic panels that reproduce the bass well are often difficult to manufacture, due to their low efficiency and their very complex radiation to control. To use isodynamic panels and take advantage of good reproduction in the bass as well as on the rest of the spectrum, manufacturers often combine them with subwoofers with conventional dynamic loudspeakers in order to complete the reproduction of the midrange transducers and acute (we are speaking more precisely of cells). Another solution, by default, comes down to making sacrifices on the style of music that we can fully enjoy on this type of speaker. In the latter case, lovers of big funky bass generally go their way when it comes to audiophile speakers operating exclusively with isodynamic cells. But, with the confinement and after two years of research work, the French brand Diptyque Audio has filed a patent which could change the situation.
To set the membrane of Diptyque Audio acoustic panels (or even other brands) in motion, the principle is different from that used by conventional loudspeakers with dynamic loudspeakers. This works by setting the membrane into vibration by magnets located on either side of it and activated according to the audio signal. This type of atypical loudspeaker is used by several High-End brands and can reach very high, even crazy prices. There have been models at affordable prices, like at Magnepan for example, but this remains the exception.
Diptyque Audio, for its part, is a French brand that manufactures acoustic panels in its own way, developing its own isodynamic technology for its speakers. We had in our hands, and appreciated, the small DP77 models. The DP107s have also been talked about, because of their relatively affordable price for this type of panel and for their great audiophile seriousness. With the confinement, the Diptyque Audio workshop switched to research mode for many months and developed the patented technology crossed push-pull.
It has nothing to do with the push-pull mounted speakers that can be found on subwoofers. Rather, it involves moving the thin 12-micron mylar membrane forward and backward – hence the term “push-pull” – using magnets, activated by coils. But instead of the coils being placed only in one direction, usually vertical, here they are crossed, vertically and horizontally, hence the name “crossed push-pull”. Filtered independently to give more control in sound reproduction, these coils activate a mosaic of more than nine hundred small square magnets. These magnets thus set the mylar membrane in vibration in a very controlled manner. techgie crossed push-pull does not concern all sound registers but simply the low end of the spectrum, materialized by the largest loudspeaker in the enclosure, or the largest cell to be precise. The audio spectrum is reproduced in the infra-bass from 20 Hz with crossed push-pull technology, right down to the low-midrange. For the upper bass, still in the main cell, one of the coils is deactivated and the membrane is only moved by a single coil. Then, a 20 mm isodynamic ribbon designed by Diptyque Audio takes over for the midrange from 600 Hz to 7000 Hz. 000Hz.
During the Munich High End, Diptyque Audio has also announced its move to new premises in Montauban, seven times larger than its current workshop. We are therefore moving from artisanal audiophile production, which had already integrated series processes, to production on a larger scale. The metal front of the Diptyque Audio Reference is made of steel plates, laser cut by an industrial subcontractor in the Toulouse region. The speaker thus presents a much more modern and high-tech appearance than the brand’s previous models. A solid block of aluminum, flat and square, takes place at the base of the enclosure; this is where the filter sits. Finally, note that the speaker is decorated with a leather finish all around.
The distribution of Diptyque Audio Reference acoustic panels is planned for the month of october 2022 at the price of €44,000 the pair. Audiophiles can choose the finish from over 200 colors at no additional cost. During our listening at High End Munich 2022, the panels were powered by Kora amps, with a B.audio DAC, all connected with o2A cables. We were therefore able to listen to a system 100% made in France. The acoustic panels impressed us with the purity and naturalness of their musical reproduction, as much as with their bass, which is really present, but of a lightness and flexibility without equal in the world of classic electrodynamic loudspeaker enclosures in bass-reflex or closed load. Bravo or rather “cocoricooo!” for these achievements which raise Diptyque Audio to the rank of the big names in high-end international Hi-Fi.
