The essence of the MRC line distilled into a compact, placement friendly speaker.

The MRB-1 is the essence of the MRC line distilled into a compact, placement friendly speaker designed to work beautifully in any music lover’s space. Thanks to careful voicing and a front-facing port the MRC-1 is equally at home on a lowboy console, on a shelf, or on a speaker stand.
While remaining very placement friendly, the MRB-1 throws an enormous soundstage, and offers the sort of dynamic, low distortion sound that leaves listeners smiling and shaking the heads wonder “how on earth did they do that?”

Tweeter

For the MRC range, Acora engineers selected a refined one-inch ceramic dome tweeter, chosen for its ability to reveal the delicate emotion and expressive detail within every performance. Its advanced design features dual neodymium magnets and a vented titanium voice coil former, delivering low distortion, wide dynamic range, and minimal compression, even at high output.
Carefully voiced for musical truth, this tweeter doesn’t just extend the highs — it brings them to life with a sense of air, nuance, and effortless clarity that invites deeper listening.

Midrange/Woofer

The MRB’s midbass driver is the beating heart of the speaker, handling the crucial range where rhythm, tone, and emotion live.
Selected and tuned by Acora engineers, this driver delivers rich, natural warmth, with the speed and control needed to convey both dynamic impact and delicate nuance.
Whether it’s the weight of a cello, the punch of a kick drum, or the resonance of a human voice, the midbass brings each moment to life with clarity and soul.Every note feels grounded, textured, and true — forming a seamless connection between the foundation of the bass and the clarity of the highs.

Crossover

The MRB’s crossover is the result of meticulous engineering and countless hours of listening, designed to ensure that the speaker itself fades away — leaving only the performance, presence, and pure emotion of the music. Every component was chosen with purpose. Capacitors and inductors from Mundorf deliver precision and transparency, while oxygen-free, continuous cast copper wiring from Cardas preserves signal integrity with effortless flow.
The connection to your system is made through custom Rhodium-plated copper binding posts, also from Cardas — elegant, durable, and sonically transparent. Together, these elements form a path where nothing gets in the way of the music — only the artist, the space, and the moment remain.
