About the Sigma 400
The Siare Sigma 400 is a premium loudspeaker model designed for high-fidelity audio reproduction. It incorporates three drivers: a 26 cm bass driver with an aluminum die-cast basket operating in a bass reflex system, a 12 cm midrange driver equipped with a high-power magnet for clear mid frequencies, and a TWM dome tweeter that offers a wide dispersion and rapid impulse response. The spatial arrangement of the drivers is carefully engineered to provide symmetrical sound in stereo use and enhance musical precision. The speaker uses a monolithic crossover filter technology exclusive to Siare, which ensures very low distortion and high musical definition across the entire frequency range. The tweeter is a fabric dome type with a special treatment for excellent frequency response and sound quality, rated at 80 Watts with a frequency range of 4000-22000 Hz and sensitivity of 89 dB. The Sigma 400 is part of Siare's 400 series and is recognized for its balance and fidelity in sound reproduction.
