Vienna Acoustics Principal Grand guide

Setup procedure for the Principal Grand subwoofer

1.In order to prevent scratches and finger-prints we have supplied with each Principal Grand a pair of our special cloth gloves. We highly recommend using these throughout the entire setup process.

2.Connect the Principal Grand subwoofer using either a pair of speaker connections, a pair of Phono (RCA) cables for stereo or a single LFE cable subwoofer cable. In each case we recommend that you discuss the best connection scheme with your retailer and purchase the appropriate cable choice.

3.Connect the Principal Grand to the AC power outlet.

4.Turn on the Master Power Switch.

Note: If the power LED does not immediately illuminate, please check that the On/Auto switch is in the Auto position. If this is the case, it will be necessary for the subwoofer to receive and audio signal before the LED will illuminate. For the setup procedure you may want to place this switch in the On-Position and then return it to the Auto-Position for normal operation.

5.For the ideal final setup as well as the most efficient use of setup time, please follow these simple dial-in instructions.

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.
