Richter Audio Merlin S6plus Bookshelf Loudspeakers Review

Richter Audio Merlin S6plus is the latest evolution in a legacy of Australian-designed loudspeakers that dates back nearly 40 years. Despite being a compact standmount speaker, its generous 165mm mid/bass driver and a sturdy 12-litre cabinet deliver a surprisingly full-bodied sound. Engineered in Sydney and crafted with precision in China, the S6plus is optimized for performance in smaller listening spaces. Backed by Richter’s mission to offer high-value, emotionally engaging audio, this model blends thoughtful design with serious sonic capability, making it a compelling choice for hi-fi enthusiasts looking to upgrade from starter systems.

The Richter Audio Merlin S6plus impresses with its expansive stereo image, unflustered dynamics, and refined tonal balance—especially given its price point. Thanks to a newly developed composite paper cone, distortion is notably reduced—especially around the 1kHz range—while the upgraded 25mm tweeter from Richter’s Premium Special Edition line brings refined high-frequency detail and increased power handling. Whether spinning synth-laden pop tracks or classic rock anthems, this bookshelf loudspeaker confidently conveys depth, presence, and rhythm without breaking a sweat—particularly when placed 15cm from the rear wall and mounted on quality speaker stands.

In a category where many competitors aim for sterile neutrality, the S6plus stands out with its warm, open, and gutsy sonic personality. While it doesn’t strive for ultra-clinical accuracy, it excels at making music feel alive and emotionally compelling. Ideal for pairing with affordable to mid-tier amplifiers, this loudspeaker delivers an immersive listening experience that’s hard to beat at this price.
