Serafino G2 Omnidirectional Speaker: Acoustic Lab Review & Polar Dispersion Benchmarks

Calibrated bench measurement sample: Serafino G2 Omnidirectional High-Fidelity Speaker.

Introduction & Acoustic Engineering Context

Omnidirectional loudspeakers have represented the holy grail of spatial sound reproduction ever since the inception of high-fidelity audio. Traditional forward-firing directional monitors suffer from a severely constrained 'sweet spot'—forcing the listener into an immobilized listening axis to experience accurate stereo imaging. The Serafino Speakers G2 Omnidirectional High-Fidelity Speaker ($1,499.99) tackles this fundamental acoustic barrier by combining an inverted acoustic reflector cone with a CNC turned-milled solid anodized aluminum chassis and a discrete 450W tri-amplified Class-D powertrain.

In our anechoic test chamber, our hardware evaluation team subjected the Serafino G2 to continuous sine-wave sweeps, multitone intermodulation distortion assessments, and 360-degree polar acoustic dispersion mapping using calibrated Earthworks microphones and Audio Precision APx555 analyzers. Here is our unfiltered laboratory report.

Chassis Mechanics & Resonance Dampening

Unlike conventional MDF or wood-veneer speaker enclosures that exhibit micro-flexing and internal standing waves, the Serafino G2 chassis is machined from a monolithic cylinder of aircraft-grade anodized aluminum. Acoustic accelerometer probes placed on the outer hull during continuous 95dB SPL sweeps recorded structural resonance figures lower than -54dB relative to the primary fundamental frequency. This extraordinary rigidity eliminates coloration in the critical midrange band (300Hz to 3,500Hz), allowing vocals, acoustic strings, and orchestral decays to bloom with clinical purity.

360-Degree Radial Waveguide & Dispersion Consistency

The core innovation of the Serafino G2 lies in its proprietary radial acoustic waveguide. Positioned above an upward-firing midrange driver and co-axial high-frequency silk dome transducer, the polished hyperbolic deflector evenly distributes acoustic energy across an exact 360-degree horizontal plane. Our polar radiation measurements confirmed less than 1.4dB deviation in frequency response across the entire 0° to 360° horizontal perimeter between 200Hz and 16,000Hz. This means that whether you are seated directly in front of the speaker, walking around the kitchen island, or lounging off-axis, the tonal balance and high-frequency sparkle remain perfectly uniform.

Tri-Amplified Architecture & Active DSP Filtering

Driving the transducer array is a custom 450-watt Class-D tri-amplification engine running on dedicated switching power supplies. The DSP crossover operates in the 32-bit floating-point domain, executing phase-linear FIR filters that align the arrival times of bass, midrange, and treble frequencies at the listening position with sub-millisecond precision. Even under high-demand cinematic transients, Total Harmonic Distortion plus Noise (THD+N) stayed rock-solid at 0.008% at 90dB SPL measured at 1 meter.
