Dual 18-inch Cinema Subwoofer

Contact Us
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 less 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 allows the enclosure to be extremely narrow, while maintaining full port length and volume.
