Aperion Audio Blue Opal Grandis GR6 6.5" 2-Way High Fidelity Bookshelf Speaker Pair
Aperion Grandis GR6 High Fidelity Bookshelf Speakers | Pair Aperion Audio marks its 25th anniversary in 2024 with the launch of the Grandis High Fidelity Bookshelf Speakers, following 24 years of technical advancements. The world of hi-fi music enthusiasts is known for its discerning taste and unwavering quest for superior sound quality. Despite facing stiff competition from long-standing speaker brands worldwide, Aperion Audio felt compelled to develop its own hi-fi speaker series. The Grandis series embodies Aperion Audio's dedication to delivering exceptional sound quality and strives to be recognized as one of the finest hi-fi speakers globally. To achieve high fidelity sound, a strong musical sense is essential, especially for the Grandis High Fidelity bookshelf speakers. Striking a balance between various aspects of performance, such as the full frequency range and driver unit design, is a complex task. Ensuring that a 6.5“ mid-bass driver can accurately reproduce frequencies down to 35 Hz, and making a tweeter produce warm, transparent high frequencies are key challenges. Developing a speaker that can cater to diverse music genres presents a significant hurdle. In the development of the Theatrus series, we engineered an exceptional coating material specifically for soft-dome midrange drivers. By precisely adjusting the physical characteristics of the soft-dome coating formula, we successfully improved the properties of the Grandis dome tweeter unit, resulting in the desired sound performance. Our current objective is to optimize the high frequency extension and reduce distortion significantly. These technological advancements have been integrated into the design of the Grandis tweeter unit. The Grandis GR6 High Fidelity Bookshelf speakers boast a 6.5-inch mid-bass driver unit that excels in producing low frequencies in a confined space, fulfilling a challenging requirement. Its exceptional sound expression in the mid-frequency range sets it apart from other designs in the market. Extensive testing led to the development of a new multi-material cone technology which we call "AFG" - Aluminum-Foam-Glass fiber, to meet our specific sound performance needs, going beyond mere physical properties. Throughout an extensive year and a half of testing and modifying, following numerous rounds of design alterations, the sound of Grandis has progressively aligned with our design vision. However, despite our efforts to tweak the drivers, we had yet to achieve a perfect match with our desired outcome. We scrutinized the driver units, cabinet crossover design, and other components, but the issue was still present. Upon reflection, we shifted our focus towards the capacitor. After experimenting with various capacitors worldwide, we discovered that an expensive capacitor met our sound requirements, albeit at a high cost. This prompted us to explore the possibility of designing our own capacitor. After thorough research and testing, we successfully developed a silver nickel alloy capacitor that perfectly complements the smoothness and transparency of the Grandis Tweeter Unit. On the occasion of Aperion Audio's 25th anniversary, we launched the GR6 & GR8, the initial models in the Grandis HiFi bookshelf speaker series. As we move forward, we have a series of other Grandis products in the pipeline that will be unveiled soon. Here's to another 25 years of exceptional sound!
