The FR-5's driver configuration included two 130mm coated paper woofers and a 25mm fabric dome tweeter, both magnetically shielded and positioned to deliver a coherent soundstage. The speakers produced a wide, deep soundstage with excellent stereo focus, and their ability to handle complex musical passages with clarity and control made them a joy for both casual listening and critical audiophile use.

Listeners appreciated the FR-5’s ability to summon significant drive and attack, with dynamic peaks and troughs rendered with precision. The bass response, powered by a rear-firing bass port, was noted for its depth and tightness, providing a solid foundation without sounding bloated. Although the speakers needed careful positioning, once properly placed, they delivered a balanced and composed sound, offering a strong performance across genres, from rock to classical.

The CR-5 centre channel was designed as part of the same Caspian series, providing a matching aesthetic and sonic signature for home theatre setups. Together, the FR-5 and CR-5 created an immersive surround sound experience, excelling in both two-channel music playback and multi-channel setups.

While the FR-5's slightly pronounced midrange and unique bass tuning added a distinctive flavour to the sound, some listeners preferred this character for its musicality and engaging presence. Despite its more forward presentation, the FR-5 maintained a sense of refinement, allowing for extended, non-fatiguing listening sessions.
