Chario Constellation Delphinus MK2 (pack of 2)

The Chario Delphinus mk2 represents the evolution of an already acclaimed model in the Constellation series by the Italian manufacturer Chario. This two-way bookshelf speaker combines meticulous acoustic design with refined aesthetics, characteristic of the brand’s philosophy. With its high sensitivity of 90 dB, it delivers remarkable performance even with moderately powered amplifiers, while maintaining the musical and natural sound signature that has made Chario renowned.

Sophisticated Acoustic Design

The Delphinus mk2 features a two-way configuration combining a 38 mm soft dome tweeter equipped with a waveguide and a 170 mm paper composite woofer. This combination achieves an extended frequency response down to 55 Hz, which is impressive for a speaker of this size. The bass-reflex system with NRS (Near Reflective Surface) technology optimizes low-frequency output by leveraging the proximity of the support surface and the diffuser structure.

The 4th-order LKR crossover at 1500 Hz ensures a seamless transition between the two drivers. This setup delivers a wide and precise soundstage with a natural tonal balance. The tweeter provides a 60° dispersion angle, ensuring uniform high-frequency distribution throughout the listening space.

Exceptional Sound Performance

The Delphinus mk2 stands out with its high sensitivity of 90 dB, double that of the Lynx model in the same series. This feature allows it to require only half the input power to achieve the same sound pressure level, making it particularly suitable for moderately powered amplifiers (minimum recommended: 30W/4Ω).

Despite its compact size, this speaker offers extended dynamics and natural timbre reproduction that defy its dimensions. The wide and precise soundstage allows for accurate localization of instruments and vocals in space, creating a striking musical presence. The midrange, crucial for reproducing the human voice, is rendered with remarkable transparency and richness.

Acoustic Integration in Domestic Environments

The Delphinus mk2 is designed to deliver excellent performance even in standard domestic environments without specific acoustic treatment. The speaker thrives in rooms ranging from 9 to 25 m², which corresponds to most living rooms and residential listening spaces.

To optimize performance, Chario offers dedicated stands that further enhance the stability and isolation of the speakers. These stands are specifically designed to maintain a calibrated distance between the speaker and the floor, ensuring maximum efficiency of the bass-reflex system. While the speaker can be placed on a shelf, using the dedicated stands is recommended to fully exploit its sonic potential.

Evolution Compared to the Previous Model

The mk2 version of the Delphinus represents a significant evolution from the original model. Chario’s engineers have refined the crossover and optimized the bass-reflex tuning to improve frequency response coherence. The tweeter now features a more sophisticated waveguide that enhances high-frequency dispersion and improves stereo imaging precision.

The 170 mm paper composite woofer has also been upgraded to provide better low-frequency articulation and reduced distortion at high volumes. These technical improvements result in even more faithful and natural sound reproduction, staying true to Chario’s philosophy of musical reproduction.

Quality Craftsmanship and Materials

The cabinet of the Delphinus mk2 showcases Chario’s Italian artisanal expertise. It combines solid walnut with high-density fiberboard (HDF) panels, ensuring both elegant aesthetics and optimal structural rigidity. This meticulous construction minimizes unwanted resonances and contributes to sound purity.

With dimensions of 410 × 230 × 330 mm (H × W × D) and a weight of 12 kg, the Delphinus mk2 boasts a high density that reflects its build quality. The available finishes include noble wood veneers that harmoniously integrate into various domestic environments, from classic to contemporary.
