This detailed comparison dives into the Sonus Faber Sonetto II G2 and Lumina II bookshelf speakers, analyzing their performance and characteristics to help discerning audiophiles choose the perfect fit. Both models are renowned for their Italian craftsmanship and premium build quality, but their sonic signatures differ significantly. We'll explore their technical specifications, including driver configurations and cabinet construction, alongside in-depth listening impressions and objective measurements. This review will examine frequency response, directivity, and impedance, revealing the nuances of each speaker’s sound.The comparison covers not only the inherent sonic characteristics of the Sonetto II G2 and Lumina II, but also their interaction with the listening environment. We’ll discuss the importance of speaker placement, room treatment, and the effect of these factors on overall sound quality. Ultimately, this detailed analysis aims to provide a clear understanding of the strengths and weaknesses of each model, assisting readers in making an informed decision based on their individual preferences and acoustic environments.
Pros And Cons
- Good directivity, especially horizontally.
- Good in-room extension to about 50 Hz.
- Boosted treble, may sound bright or analytical.
- Dip in the upper mid-range, leading to a slight lack of detail, attack, and clarity.
- Resonance around 700 Hz, resulting in a 'nasly' sound.
- Needs more room to breathe if equalization isn't used to tame the bottom end.
- May require positioning further from the wall (2 feet or more in ideal conditions).

Sonus Faber Sonetto II G2: Specifications and Design
The Sonus Faber Sonetto II G2 is a bookshelf speaker retailing for approximately $2750. It features a 1 1/8 inch damped Apex Dome silk dome tweeter and a 6 1/2 inch cone woofer. The base incorporates a mixture of concrete, aluminum, and steel for enhanced venting and cabinet stability.

Weighing approximately 23 lbs each, these speakers are meticulously crafted in Italy and are available in several colors, including light color walnut, black, and a darker walnut finish. The build quality is evident, hinting at the premium price point.

Sound Characteristics and Comparisons
The Sonus Faber Sonetto II G2's sound signature is not entirely neutral, yet it avoids the excessive brightness often associated with other Sonus Faber models. The reviewer notes a certain tonal inconsistency across the brand's lineup, making it difficult to predict the sound profile.
Compared to the Lumina II, the Sonetto II G2 presents a less aggressive treble response, although still somewhat elevated. The Lumina II was described as exceptionally bright, potentially overwhelming to listeners preferring a more balanced or warmer sound.
Frequency Response and Room Placement
Measurements reveal a slight dip in the upper mid-range, potentially resulting in a perceived lack of detail and attack. A treble boost is also present, which might be perceived as analytical or detailed depending on listener preference. Room placement significantly impacts the sound, with the reviewer suggesting the need for more space between the speakers and the walls to mitigate bass buildup.
Optimum placement is about 2 feet from the back wall, potentially more if equalization isn't used to control the low frequencies. The reviewer also highlights the importance of ear height relative to the tweeter for optimal vertical imaging.
Room Treatment and Directivity
Sidewall room treatment is generally not recommended, due to the speaker's good horizontal directivity. The relatively linear narrowing of the horizontal dispersion pattern means reflections from the side walls will sound similar to the direct sound, negating the need for significant absorption.
However, if the room is excessively echoey or boomy, general room treatment is still recommended to address those specific issues. The vertical directivity is more critical, requiring the listener to be seated at the tweeter's height for optimum sound.
Detailed Measurements and Analysis
Detailed measurements, including frequency response, directivity, harmonic distortion, and dynamic range, are presented. The measurements support the subjective listening impressions, revealing a resonance around 700 Hz and a treble boost. The horizontal directivity shows a controlled narrowing, which is deemed positive.
Impedance is relatively low, making the speakers easy to drive. Equalization suggestions are provided to further refine the sound profile and address the 700 Hz resonance. The reviewer also offers a direct comparison to the Lumina II's measurements.
Conclusion: Sonetto II G2 vs Lumina II
Both the Sonus Faber Sonetto II G2 and Lumina II present elevated treble responses; however, the Sonetto II G2 is less aggressive. The Sonetto II G2 offers better bass extension and dynamic range, while the Lumina II has a more nonlinear horizontal dispersion pattern, requiring more careful room treatment.

The Sonetto II G2 is a capable speaker, but its slightly boosted treble and mid-range dip might not appeal to listeners seeking a truly neutral sound. The Lumina II, despite its brighter sound, might be preferred by those who appreciate a highly detailed, analytical presentation. Ultimately, the best choice depends on individual preferences and listening environments.
