Piega Coax 611 Gen2 Floorstanding Loudspeakers

Piega is a Swiss loudspeaker maker that has spent four decades doing one thing better than almost anyone else: building ribbon transducers and mating them to extruded aluminum cabinets that disappear from the music. The company was founded in 1986 on Lake Zurich, and every speaker that wears the Piega badge — from the entry models to the limited-edition flagships — is still assembled by hand in Horgen, Switzerland. The ribbon-tweeter architecture that defines the brand is not borrowed technology. Piega develops and manufactures its own ribbon drivers in-house, including the coaxial ribbon module that places the midrange and treble at a single physical point and resolves the time-alignment problem that conventional two-way and three-way crossovers can only approximate. The cabinets are pulled from a single piece of extruded aircraft-grade aluminum, internally damped with Piega's Tension Improve Module to remove panel resonance before it can color the sound. The result is a presentation that listeners describe in the same vocabulary year after year: fast, clean, dimensionally precise, and free of the boxy signature that almost every traditional cabinet imposes on the music.

The Coax 611 Gen2 is the middle floorstander in the Coax series and, for many rooms, the model that lands the cleanest tradeoff between Piega's flagship-tier resolution and a footprint that doesn't dominate the space. The C112+ coaxial ribbon module brings the same point-source midrange and treble integration that defines the larger Coax 811, scaled to a driver complement of two 160 mm UHQD woofers paired with three 160 mm UHQD passive radiators in a 117 cm extruded aluminum cabinet stabilized by Piega's Tension Improve Module 2. The bass alignment is tuned for fast, articulate low frequencies rather than maximum extension — the speaker reaches 32 Hz cleanly, which covers virtually all musical content, and trades a few hertz at the bottom for tighter integration and easier room placement than full-range alternatives demand. Reviewers consistently describe the 611 Gen2 as the Coax that punches well above its tier on imaging precision and tonal honesty, with a top end that sounds neither rolled-off nor etched.

The Coax 611 Gen2 was named Loudspeaker of the Year (2025) by The Absolute Sound and received the hi-fi+ Winner award (2026). For owners who want the Coax 611 in something beyond the standard aluminum, black, or white finishes, the Coax Excellence program offers eight additional colors hand-finished in Switzerland: Blue Lagoon, Misty Green, Shiny Ash, Desert Gold, Bordeaux Red, Havana Tobacco, Autumn Bronze, and Alpine Stone.
