A 2.5-way floorstander with high sensitivity (91 dB) and twin 20 cm Polyglass woofers — for people who play rock, electronic and dense genres loud and want drive and scale rather than analytical neutrality. Best in 18–35 m² rooms, needs no powerful amplifier (25 W minimum per the manufacturer), and the ±2 dB treble switch tunes it to the room.

It is built for loud listening to dense music in 18–35 m² rooms; soundex.ru notes “outstanding macrodynamics” with no compression at climaxes. If you value gentleness, detail and chamber vocals more, audition the Gamma 3.02 next to it; for rooms under 15 m² take the bookshelf Sigma 1.01 with the same character.
