c.Crossover: After adjusting the Phase-Control, it will be necessary to determine the best crossover range for your in-room performance. Turn this control to the lowest setting available. It may be necessary to again adjust the overall volume. Most frequently at this point it will be necessary to raise the volume a position or two. Then adjust or raise the crossover setting until the overall bass performance begins to become overwhelming or “boomy.” When this happens, lower the crossover setting until the “boominess” goes away.

e. Fine Adjustments: At this point you may find that a position or two higher on crossover will sound better with the overall volume a position or two lower. This will produce a slightly “warmer” bass contour while the opposite of having the volume a bit higher but a crossover setting that is slightly lower will produce a “faster” and more powerful lower bass output. This final fine adjustment process is of personal preference and thus listening to a couple different pieces of music should be used for this step.

Note: It is usually better to use a lower crossover setting with slightly higher overall volume settings in order obtain the optimum in room bass extension. Since all speakers have different performance in all rooms and with different associated other equipment, it is impossible to determine what the final setting for the crossover, gain or even phase will ultimately be. The only way to properly setup this device, or any other piece of a fine audio or audio/video equipment, is by listening.

Thank you and Happy Listening!

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.
