Acora Acoustics SRB
THE CONCEPT
From the beginning, we chose a different path. We asked: what if the cabinet didn’t hold the speaker back, but set it free? That question led us to stone — a material as timeless as music itself. Our precision-crafted stone enclosures eliminate resonance and distortion, allowing every note to emerge with stunning clarity and purity.
Why Stone?
At Acora, performance has always come first. Our pursuit of the most faithful, uncolored reproduction of music led us to take a deep look at a critical — yet often overlooked — factor: cabinet resonance. For decades, wood has been the material of choice for speaker enclosures, used by the vast majority of high-end audio brands.
But even with the most advanced construction techniques, we found that wood simply couldn't escape its nature — it always added something to the sound. A subtle coloration. A soft veil over the truth.
We looked further. Aluminum, composites, exotic materials — each with their strengths, but none quite delivering the neutrality and control we demanded. Then we found our answer: natural stone. Stone offered everything we were searching for:
1. Virtually no interaction with the energy from the speaker cones — letting the drivers speak freely.
2. High mass, providing rock-solid stability, enhancing soundstage depth and stereo focus.
3. Unique, bespoke character — no two pieces are alike, making every speaker truly one of a kind.
4. Timeless aesthetic that brings elegance into any home.
Tweeter
A carefully selected soft dome tweeter, voiced for smooth, extended highs, integrates effortlessly with the system. Requiring no resistors in the signal path has preserved clarity, immediacy, and musicality.
Midrange/Woofer
A custom-voiced paper cone woofer delivers natural warmth, fast transients, and deep, articulate bass.Tuned by Acora for tonal balance and dynamic expression, it anchors the music with authority and grace.
Crossover
The SRC crossover is the result of exacting engineering and countless hours of listening. Designed for perfect phase alignment and driver integration, it allows each component to perform at its best — with effortless coherence and dynamic ease. Internally, the layout is optimized for signal purity and mechanical isolation.
