Aperion Grandis GR6 HiFi Bookshelf Speaker Pair

Aperion Audio marks its 25th anniversary in 2024 with the launch of the Grandis High-Fidelity Speaker Series, 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 HiFi bookshelf speaker. 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 unit can accurately reproduce frequencies lower than 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 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 physical 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 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 GR 6 & GR 8, 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!

Key Features

1.1" Silk-Dome Tweeter with Special 

aperion-audio-grandis-tweeter

The Grandis series showcases a remarkable 1.1”(28mm) silk-dome tweeter with a special coating, delivering an exceptional blend of power, precision, transparency, and finesse in sound reproduction. Its design, in collaboration with the waveguide panel, maximizes both high-frequency scattering and efficiency, ensuring an impeccable fusion of sound accuracy and natural reverberation. Moreover, Aperion has ingeniously engineered a mid-bass woofer that harmonizes flawlessly with this tweeter, culminating in a distinctive, natural, and well-balanced sound characteristic unique to the Grandis series.


6.5" - A.F.G. Cone Long-Throw Mid-Bass Woofer

aperionaudio-grandis-6.5inch-AFG-sandwich-Woofer

Our mid/bass driver is the result of meticulous development in our dedicated laboratory, designed to perfectly complement the Grandis speakers. Aperion has invested significant time and effort in testing and innovating the raw materials used in the woofer cone by creating our own material. The A.F.G multi-material cone technology cone woofer is a crucial element in achieving the high-quality sound reproduction from Grandis. Consisting of aluminum, foam, and fiberglass layers, this multi material cone structure enables the mid-woofer to effectively handle the rigidity and damping of the woofer unit. With advantages such as optimized frequency response, precise phase response, excellent sound quality, extended low frequencies, balanced highs, and minimal distortion, the A.F.G. multi-material cone technology ensures an exceptional audio experience.

The sloping front baffle design creates an even phase alignment between treble and bass drivers.

 

Heavy copper rings mounted

aperionaudio-grandis-heavy-copper-ring

Heavy copper rings mounted above and below the T-shaped pole piece reduce non linear- and modulation-distortion as well as increases the overload margin.


Advanced Crossover

Time-intensive iterative designing and fine-tuning of the crossover networks have resulted in a smoother, more neutral, and better balanced frequency response across the whole range. Enhanced phase integration between the tweeter and midrange drivers have also resulted in a cleaner, more open sound in the transition regions. The Grandis speaker employs superior customized components, which include high quality thin film capacitors to provide minimum dielectric loss, customized Aperion internal wiring with spade connectors to make upgrading a breeze, and we even went as far as customizing the PCB board with an Aperion red color to represent our love of great sounding audio!


HiFi Sound Quality

The Grandis Bookshelf reproduces complex and dynamic music genres with deep, controlled, and accurate bass responses. It is perfect for audiophiles and music enthusiasts who demand the best sound quality and performance.


Rear Port Tube

aperionaudio-grandis-bookshelf-speaker-rear-port

A rear reflex port on the GR6 bookshelf speaker reduces air-leak noise with increased bass performance.


5-way gold-plated binding posts

aperionaudio-grandis-speaker-binding-post

Bi-ampable is the techie way of saying you can connect one amplifier to the woofer and the other to the tweeter. Separating the low- and high-frequency wiring helps eliminate interaction, isolate power and reduce distortion.

 

Custom Lightweight Magnetic Grilles
