Focal 21 V2 8" 200W RMS Polyglass Car Subwoofer

Since its very beginning, Polyglass has symbolized the very heart of the entire Focal Car line-up. The main characteristics of this line combines advanced technologies, total manufacturing control and unique know-how. This process has been continuously developed for more than twenty-five years, which still continues today, to reach a sound quality that is universally recognized as excellent while still remaining affordable. To arrive at this subtle balance, extreme care is taken over multiple production stages, which is why all of the key elements found in the Polyglass line are entirely manufactured by Focal in-house.

The Polyglass cone, fully exploits the remarkable properties of glass, an even covering of micro glass spheres over the entire cellulose pulp paper cone greatly increases its rigidity without adding significant weight. The overall finesse of the Polyglass range comes from a combination of the tweeter and woofer, creating a neutral sound with excellent detail at recreating the emotion of music.
