Test Bench: The L26ROY 10” Subwoofer from SEAS

This month I characterized the 10” L26ROY subwoofer from SEAS’ new Extreme line. The SEAS L26 series from SEAS was popularized by several of Siegfried Linkwitz designs (sold by Madisound as kits), including his "pièce de résistance," the LX521.4, which utilized four L26RO4Y subwoofers (the four-layer version). These 10” woofers were built in Taiwan for SEAS, but that production has now been brought home to Norway and reintroduced as the Extreme subwoofer line. The new L26ROY has a well-appointed feature set. This article was originally published in Voice Coil, April 2019.
