Sigma Acoustics · M Series
M8
The 2-way system that redefines the concept of compact loudspeaker in the Serie M range.
Sonic characteristics
All the power of musicin a compact tower.
The new M Series challenges the laws of physics to bring the extension and dynamics of large systems into compact spaces, with a 6 dB crossover for maximum phase purity.
Equipped with the iconic Heil AMT tweeter and a 19 cm Egyptian paper cone woofer with neodymium magnet, floor-ported bass-reflex loading. Sigma DNA meets Heil technology for precise transients.
Dispersion
Perfect dipolar dispersion.
The Heil AMT tweeter with TOE adjustment allows optimal dipolar dispersion for any environment: three-dimensional soundstage, wide and defined sonic image.
Minimal footprint, astonishing sound front. Proof that a compact loudspeaker can sound big.
The cabinet
Hand-built in Italy.
Cabinets with clean lines, mirror-polish polyester lacquer finishes and fine wood veneers, hand-finished to integrate into any contemporary environment. First-order 6 dB/octave linear-phase crossover.
