The Isis loudspeakers by Trenner & Friedl are a bold and uncompromising statement—where acoustic engineering, fine craftsmanship, and musical integrity converge. Designed to fill large spaces with power, warmth, and delicacy, Isis delivers music as an immersive, organic experience that honors both the art and the artist.
Timeless Craftsmanship, Noble Materials
Each enclosure is handcrafted from multi-density birch plywood, selected and shaped to optimize resonance control and projection. The midrange chamber features precision-tuned ventilation, ensuring vocal frequencies are reproduced with clarity and natural tone.
The surface is finished with seven layers of lacquer, combining elegance and durability. Meanwhile, the paper cone drivers are hand-treated with six coats of Italian balsamic oil lacquer, enhancing stiffness and acoustic responsiveness. The solid beech base lends the speaker structural integrity and vibration control.
Technology Meets Emotion
Isis is a three-way floorstanding loudspeaker featuring high-performance drivers:
15" paper-cone woofer for deep, authoritative bass
8" paper-cone midrange for organic vocal reproduction
1.75" titanium compression tweeter, TiN-coated (titanium nitride) and horn-loaded for ultra-high resolution and airy extension
The precision crossover network incorporates Mundorf premium components—oil/silver capacitors, aluminum foil coils, and MOX resistors. Internal wiring is by Cardas Audio, arranged using the Golden Ratio, and the terminals are crafted from pure copper, also from Cardas.
