5-Year Warranty

Every Sonofinity system ships with a comprehensive 5-year warranty covering drivers, amplifiers, and DSP modules — because engineering confidence means standing behind what we build.

Dedicated System Design

Our acoustic engineers work directly with you to model your room, recommend placement, and optimize DSP profiles — included with every purchase, not sold as an add-on.

Modular Architecture

Swap amplifier modules, upgrade DSP firmware over-the-air, and expand with additional units — your Sonofinity system evolves with your space without replacing hardware.

Equal Loudness Contour
Perceived Loudness vs. Frequency (ISO 226)

Human hearing is far less sensitive at low frequencies. At 20 Hz, roughly +40 dB more SPL is needed to perceive the same loudness as at 1 kHz. Sonofinity systems deliver the headroom required to overcome this psychoacoustic gap.

Headroom Analysis
SPL Headroom Above Reference Level

Reference cinema level is 85 dB at the listening position. The bars below show how much headroom each model provides above this baseline — critical for dynamic peaks in film soundtracks and music.
