SGR Audio’s CX4F Mk.2 is a revered, world-first active loudspeaker that delivers exceptional clarity and dynamics without needing external power amps. At A$10,000, this listing sits just under the median of A$9,747 and well below the 75th percentile of A$10,031, making it a fair—and arguably excellent—deal in the current used market for this product.
This is a standout buying opportunity because the CX4F Mk.2 features groundbreaking “Current Drive” amplification, a superior tweeter with extended response to 30 kHz, and built-in parametric EQ and boundary compensation. Its Australian-made fit and finish, original-owner condition, and rarity (only 25 pairs made) add meaningful upside. For a well-loved, technically advanced speaker at a fair price, there’s no material caveat—just a compelling chance to own a high-end icon.

SGR Audio emerged from Melbourne, Australia, over two decades ago, driven by founder Stuart Graeme Ralston's passion for music's purest reproduction. Ralston began experimenting with speaker designs more than 16 years ago, refining cabinetry, drivers, crossovers, and aesthetics in pursuit of perfection. What started as a boutique loudspeaker venture has evolved under his leadership—and alongside family involvement, including his father Harry—into a forward-thinking manufacturer with a state-of-the-art R&D facility in Melbourne and global distribution across Australia, New Zealand, North America, and Asia.
The brand focuses primarily on high-end loudspeakers, pioneering innovations like the world's first current-drive models, alongside both active and passive designs that blend exceptional aesthetics with performance. Their portfolio has expanded to include premium hi-fi equipment racks featuring sorbothane isolation and anti-vibration engineering, capable of supporting up to 100kg loads. All products are 100% Australian-made, emphasizing precision craftsmanship for discerning listeners.
SGR Audio holds a strong position as a niche boutique player in the high-end market, earning acclaim for world-class sound and presentation—most notably at the 2018 Munich High End show, where it stood alongside global elites. Today, it confidently competes on the international stage, delivering flawless audio solutions free from noise and distortion.
