Tweeter & waveguide

Sound as it’s meant to be heard.

At the heart every speaker in the 1528 Series, is a sophisticated 3-way design featuring a custom premium 28mm Lithium-Magnesium tweeter, offering unparalleled detail and dynamics. Housed within a controlled directivity waveguide, it ensures that high frequencies are stunningly clear and detailed and precisely directed for optimal sound dispersion across your listening space. The result is an expansive soundstage that immerses you fully in your favorite music and soundtracks.

Midrange 

Lifelike clarity and seamless sound. 

The over specified custom 5″ Carbon-Graphene midrange driver combines incredibly light and stiff materials to provide exceptional accuracy and dynamics, while reducing distortion to the bare minimum. It delivers rich, natural sound that seamlessly blends with crisp highs from the tweeter, making notes, dialogue, and musical detail come alive with incredible realism. A perfect partner for the tweeter-waveguide combination.

Woofer 

Feel the power of deep, lifelike, dynamic bass. 

Our new, custom-designed 8″ aluminum long-throw bass drivers have inverted surrounds for a sleek, integrated design and housed in a prism structure for added stiffness. Everything comes together in a robust, acoustically optimized HDF cabinet, resulting in a dynamic performance with deep, impactful bass that you feel as much as you hear.

Perfect Timing, Flawless Reproduction

Experience every note with precise, in-phase sound

Our innovative, precision-engineered, and acoustically time-aligned driver baffle ensures every note is delivered with pinpoint precision, creating a coherent and dynamic listening experience that is always in step with the listener. This functional yet innovative design effectively solves the inherent challenge of aligning multiple drivers. By curving the baffle, we achieve a mechanically clean solution that avoids adding unnecessary complexity to the crossover, preserving the purity and integrity of the sound. 

“The curved front baffle of the 1528 series isn’t just for looks—it plays a crucial role in achieving an incredibly lifelike and engaging performance.”

Thomas Gunvaldsen, Arendal Sound CTO

Personalize Your Sound

Perfect your listening experience

The 1528 Series offers both ported and sealed modes, allowing you to customize the bass response depending on your individual room acoustics and personal preference. Choose an open port for maximum output and the lowest bass extension when the speaker is free standing. Or go sealed for a tighter, faster bass response when the speaker is close to a wall or corner. 

“Sounds great as a front stage speaker, for music as well as movies.”

Thomas Gunvaldsen, Arendal Sound CTO

Frequency

Frequency response does not reflect maximum output but shows its true response in a anechoic chamber. Typically you will see an elevated response in the bass response below 40Hz in room due to room gain, which can add around 6dB pr. octave under 40Hz depending on the size of your room.
