Beethoven Baby Grand
The Revelation of the Unexpected
Listening for the first time to our new BEETHOVEN Baby Grand REFERENCE™ leaves you breathless with a few burning questions: How on earth is this slim beauty able to create such a soundstage? Where is the hidden subwoofer? And where does this intensity come from?
At the heart of the design stand our brandnew spidercone drivers, one 6 inch midrange and two 6 inch woofers, all with our patented flat spidercone within a new construction, consisting of 2 distinct cones – the all new Composite Cone. The plane surface of the spidercone offers the advantage of precise, piston-like movement. Any diaphragm should move in and out as one unit, not as a quivering mass of uncorrelated vibrations. It should move as a perfectly-solid piston. The flat cone is extremely stiff, with bracings of a height of 18 mm (bass) and 14 mm (mid), yet light, respectively, further reinforced by glasfibers in our new X4P™ mixture.
The rearside bracings are constructed in a way that the whole impulse energy is allocated evenly via the whole surface of the flat cone. Every square centimeter delivers the same impulse as its neighbours, which results in revolutionary impulse response control. As our cone/diaphragm-construction builds upon a very large voice coil, the
radiating surface in its middle is large, thereby making it an significant sound determinant. The countless listening testings brought forth such an unexpected unique combination the we gave it a new name, the Composite Cone.
The 5 cm area is now an inverted dome made of woven fabric, double-coated on its rearside. Perfection was achieved by listening to various axial positions, with extraordinary homogenous results by employing a recessing of 8mm. The sum total of the features of the Composite Cone is a peerless symbiosis. Furthermore, one of the reasons why the woven fabric center cone interacts so nicely, is its affinity to the fabric material of our highly musical, hand-coated silk dome tweeter, designed by Vienna Acoustics, hand-crafted by a Scandinavian team of specialists.
Like its grander companion, BEETHOVEN Baby Grand REFERENCE™ features our new, exclusive handcoated silkdome tweeter, which reveals even the slightest nuances with natural ease, while extending well down into the midrange regions. The result of this carefully chosen combination creates a milestone in terms of naturalness, clarity and ease of reproduction.
The crossover circuitry possesses both, the elegant simplicity of soft filters – pure first-order, 6 dB per octave slopes to Bessel second order – and the essential complexity resulting from listening, needed to weave dexterously the drivers‘
output into a cohesive system. All decisions concerning individual components and the layout of the circuitry
were as always made through extensive listening tests. Specially selecting each component results in a harmonious musicality, while a sophisticated layout helps in clarifying instrumental timbres.
The tradition of unrivaled finish quality continues with BEETHOVEN Baby Grand REFERENCE™, providing the warmth and beauty of real wood, as well as the highest standards in true piano lacquer finish.
Not apparent to the eye, but all the more important to complete the homogenous whole, is the scientifically balanced bracing structure, as well as the absolutely airtight separate enclosure for the Composite Cone midrange driver.
Extensive listening comparisons and tests by our founder and designer.
