Vienna Acoustics Principal Grand guide

4.Servicing: Do not attempt to service the Principal Grand subwoofer beyond that described in the operating instructions. All other services should be referred to qualified service personnel.

5.Indoor use: Principal Grand is designed for indoor use only in a dry, domestic environment and for use within a temperature range of 10° – 40°C (50°

– 105°F).

6.Objects and liquid damage: Do not let objects or liquids fall into the Principal Grand. Do not place a container with liquid on top of this product.

7.Water and moisture: Do not operate the Principal Grand near water, for example near a bath-tub, or in a wet basement nor near a swim- ming pool.

8.Wall or ceiling mounting: Principal Grand is neither suitable for mounting into the wall nor for mounting on the ceiling. If you choose a position on the wall or on a shelf, it will be necessary that the subwoofer be properly secured into position. Otherwise the subwoofer could fall due to the exceptional vibrations that can cause the unit to move or “walk.”

9.Ventilation: Be sure to position the subwoofer so that its location or position does not interfere with its proper ventilation. The rear of the Principal Grand contains a metal panel that acts as a heat sink for the amplifier. It is particularly important that this area be clear to allow for proper air flow.

Principal Grand specifications

Vienna Acoustics, a renowned name in the high-fidelity audio industry, has long been celebrated for its exceptional loudspeakers that combine artistry with cutting-edge technology. One of the standout models in their lineup is the Principal Grand, a speaker that epitomizes the brand's commitment to delivering an unparalleled listening experience.

The Principal Grand features a beautifully crafted cabinet that not only enhances its aesthetic appeal but also plays a crucial role in sound quality. Made from high-density MDF with a luxurious veneer finish, the cabinet is both rigid and inert, minimizing unwanted vibrations that can color the sound. This meticulous attention to detail in construction ensures that the audio produced is true to the original recording.

At the heart of the Principal Grand’s performance is its innovative driver technology. The speaker employs advanced drivers, including a 12-inch woofer designed to deliver deep, controlled bass response. This is complemented by a 4-inch midrange driver that excels in reproducing vocals and instrumentals with precision and clarity. Additionally, the unique D'Appolito configuration, where the midrange and tweeter are aligned vertically, ensures a coherent soundstage and broad imaging, allowing listeners to engage fully with the music.

One of the key technologies integrated into the Principal Grand is the proprietary Air Motion Transformer (AMT) tweeter. This driver design enables the reproduction of high frequencies with remarkable accuracy and detail, offering a transient response that is often described as "effortless." The AMT tweeter also provides a wider listening area, making it easier to enjoy the exceptional sound even from off-axis positions.

The Principal Grand's crossover network has been meticulously engineered to ensure seamless integration between drivers, resulting in a coherent and balanced sound. Components in the crossover have been carefully selected for their quality, contributing to the overall fidelity of the speaker.

Furthermore, the Principal Grand is designed to be versatile, capable of fitting seamlessly into various audio setups, whether for hi-fi stereo listening or as part of a multi-channel home theater system. Its sensitivity rating allows for compatibility with a wide range of amplifiers, ensuring consumers can achieve optimal performance regardless of their existing equipment.

In summary, the Vienna Acoustics Principal Grand stands as a remarkable achievement in loudspeaker design. With its combination of aesthetic elegance, advanced technologies, and superior audio performance, it is an ideal choice for audiophiles seeking not just a speaker, but a gateway to an immersive musical experience.
