Vienna Acoustics Haydn Grand - Symphony Edition Loudspeakers



Haydn’s music is known for its lyricism, from which vibrant tonal colors and brilliant harmonic structures are drawn out of deceptively simple arrangements.

Similarly, the Haydn Grand’s deceptively simple driver complement of a 6” X3P mid-bass driver and refined 1” triple stacked silk-dome tweeter centers around the groundbreaking airflow control wedge bass reflex port (also found on the Bach Grand) that serves to virtually eliminate port noise, allows for increased placement flexibility, and provides an extraordinarily compact driver configuration by positioning the tweeter on the front of the wedge.

A compact 2-way monitor, Haydn Grand features exceptional imaging, resolution and linearity, challenging the performance of the finest floor standers.

Features:

Most notable of the many unique technological features found in the Haydn Grand is the ground breaking bass reflex port air-flow control wedge. Not only does this assembly allow for a front port configuration that increases placement flexibility, by virtually eliminating port noise, but it also provides an extraordinarily compact driver arrangement by positioning the tweeter on the front of the wedge. Both features contribute to an unrivaled level of performance in its class.

The unique construction works by way of an inner reflex port that vents air towards a wedge positioned at the throat of the port. The cutting-line of the wedge devides the airflow into two streams, which then flow in a specially designed and extensively optimized flare. The relationship of the wedge and the flare is of critical importance, and are precisely determined to achieve

a) maximum bass support for the system, and
b) the reduction of all standing waves in the port (or port noise) by –12dB.

The wedge fulfills additional and very welcome functions in the design. As mentioned above, the large size of the wedge allows the tweeter to be mounted within the throat of the port, resulting in a very compact driver arrangement that improves phase coherency and overall performance by creating a near point-source configuration. In addition, the large internal volume allows for a chamber to vent the back wave of the driver. To optimally use the chamber, a unique circular back wave pass through slot runs the entire circumference of the back of the driver, as opposed to a central hole. Because of this feature, the specially designed tweeter for this assembly profits from unconstrained air-decompression that approaches the theoretically ideal conditions of free field construction. As a result, the tweeter dome operates unconstrained, even as it descends into the lower midrange.

The entire assembly is constructed of aluminum, produced by expensive high pressure die-cast tools.
