Focal's Polyglass subwoofer uses precision craftmanship and advanced materials to create a big bass impression. Focal creates the Polyglass cone by depositing a layer of hollow glass microbeads over a layer of cellulose. This unique material combines the warm sound of cellulose with the incredible strength of glass, for a cone that responds rapidly with low resonance. The exceptionally resilient zinc alloy basket teams up with the Polyglass cone, butyl rubber surround, and an advanced motor structure to deliver uncolored bass that'll please the discerning ear.
The 21 V2 8" subwoofer handles up to 250 watts RMS, and Focal optimizes this sub to work in sealed enclosures for the best sonic results. Complete your system with a compatible amp and wiring to experience Focal's bass finesse.
