Acora Acoustics QRC-2

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.

It wasn’t the easy path, but it was the right one.
 Because when the enclosure disappears, all that’s left is the music.

THE CABINET

At Acora, we craft our enclosures from precision-machined natural stone, chosen for its rigidity, mass, and acoustic inertness. These properties allow our speakers to deliver music with exceptional clarity, focus, and emotional depth.

Every cabinet is shaped with meticulous care, resulting in a structure that performs flawlessly and showcases a distinct, timeless beauty. No two are alike — each one is a unique expression of natural elegance. This is where form meets function — and where the music truly comes to life.

DRIVERS

The SRC series is built around a carefully selected and expertly refined driver set, each one modified and perfected by Acora to meet our exacting standards — not just for precision, but for musicality.

The midrange and bass drivers, based on renowned paper cone designs, are individually tuned to deliver natural warmth, dynamic energy, and lifelike tonal balance. Through proprietary adjustments and voicing, we've enhanced their ability to reveal subtle textures and emotional nuance, resulting in a sound that feels effortlessly alive.

In the high frequencies, a beryllium dome tweeter brings sparkling extension, speed, and air, carefully integrated to maintain cohesion and natural flow. Our tuning ensures the treble remains clear and detailed, yet always inviting.

The SRC drivers work in harmony to serve that singular vision: authentic, emotionally engaging sound that draws you in and holds you there.

Tweeter

A carefully selected beryllium dome tweeter, voiced for smooth, extended highs, integrates effortlessly with the system — requiring no resistors in the signal path, preserving 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.
