The SB-2180 features two 18” (457 mm) woofers with 4” (102 mm) voice coils for extended bandwidth low-frequency reproduction. With an enclosure depth of fewer than 17 inches (452 mm), the SB-2180 is one of the narrowest dual-driver subwoofers available, which dramatically reduces space requirements behind the screen. A unique folded port design makes the enclosure minimal while maintaining full port length and volume.
