Delphinus MK2
Dynamic authority and effortless efficiency distilled into an elegant standmount design.
True scale requires moving air with absolute control. Standing as the larger, more powerful bookshelf anchor within the Constellation MK2 line, the Delphinus MK2 is specifically engineered to charge rooms between nine and twenty square metres with realistic concert-level dynamics. It masterfully solves the classic small-speaker dilemma, yielding genuine low-frequency extension without demanding a punishingly massive power amplifier.
By deploying a generous 170mm mid-bass driver alongside Chario's signature 38mm soft dome, the speaker benefits from a massive surface area advantage over typical class competitors. This design configuration results in an incredibly efficient conversion of electrical power into acoustic energy, allowing modest solid-state or valve amplification to unlock breathtaking dynamic swings.
Its sonic delivery is marked by a rich, deeply texturized physical presence that breathes lifelike body into acoustic instruments and vocals alike. Low frequencies dive smoothly down to 55 Hz with an unforced, bouncy pace, while the expansive soundstage projects well beyond the cabinet boundaries to leave only the pure architectural shape of the music intact.
Key Features
01
High-Efficiency 170mm Woofer
The custom-formulated paper compound cone provides a substantial surface area that extracts deeper mid-bass dynamics while requiring half the input power of smaller monitors.
02
Oversized 38mm T38 Waveguide Tweeter
A massive soft-dome design that allows for an exceptionally low 1500 Hz crossover point, preserving critical vocal frequencies from phase distortions.
03
Near Resonance Surface (NRS)
A proprietary down-firing reflex system that halves driver displacement for a given sound pressure, significantly reducing harmonic distortion while boosting bass efficiency.
04
Solid Timber Coupling Enclosure
Hand-assembled Side panels of seasoned solid Italian walnut decouple the dense HDF core, using contrasting mass densities to naturally scatter cabinet resonances.
Chapter 01
Acoustic Efficiency
The defining technical achievement of the Delphinus MK2 is its impressive 90 dB sensitivity rating. In practical terms, it operates at twice the efficiency level of the smaller Lynx model, meaning it requires half the amplifier wattage to achieve the exact same sound pressure level. This makes the speaker an incredibly versatile partner for a wider range of high-quality amplifiers, including low-power Class A topologies and classic valve designs that typically struggle to drive modern compact monitors.
Chapter 02
The NRS Advantage
By firing the bass reflex port downwards onto a precisely calibrated boundary surface rather than out the back, Chario's Near Resonance Surface technology fundamentally alters room interaction. The floor boundary loads the air column evenly in a 360-degree omnidirectional pattern, doubling low-frequency efficiency. This clever engineering allows the 170mm woofer to work effortlessly, maintaining structural control and eliminating the chuffing artifacts associated with traditional high-velocity rear ports.

Listening Notes
In the listening chair, the Delphinus MK2 sounds remarkably big, warm, and physically authoritative. The midrange is beautifully fleshed out, capturing the woody resonance of acoustic guitars and the chest depth of male vocalists with effortless realism. Because the crossover is executed out of the primary human hearing band via a fourth-order filter, the handoff between drivers is completely seamless, creating a vast, coherent stereophonic image that completely floats free of the solid walnut enclosures.
