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.

In this review, Oliver A. Masciarotte shares his experience with the surprising SB Acoustics Rinjani and Ara speaker kits, which feature the high-end Satori TW29R Tweeter, the MW16P-4, and the MW16P-8 midwoofers from the brand. Masciarotte had the opportunity to live for some weeks with these exquisite Rinjani speakers - a name inspired by the famous volcano mountain in Lombok, Indonesia, a place of immense natural beauty.

On March 2003, Edward T. Dell, Jr., audioXpress founder, published a complete build project for the SEAS Froy Mk3, an improved version of the original Froy kit, designed by Murray Zeligman, who also designed the original FROY kit. The Froy Mk3 kit uses two W15CY001 woofers and a single T25CF002 "Millennium" tweeter mounted in a D'Appolito configuration. In the subsequent April 2003 edition, audioXpress published a complete review of the Froy Mk3, with measurements by Joseph D’Appolito, and listening evaluation from Dennis Colin.

The results for SEAS Fabrikker's intense R&D program keep showing with more applications for the company's new generation high-quality drivers. Recently announced by Danish company PBN Audio, the new CX871 speaker kit features two different SEAS drivers: the H1699-08/06 MR18REX/XF 7” Midrange Coaxial Loudspeaker, and 2x H1208-08 L22RN4X/P 8” Aluminum Cone Woofer. The result was recently presented by Madisound at the LAAS – Los Angeles Audio Show.

One of the most important speaker building projects published by audioXpress, THOR was designed by Joseph (Joe) D'Appolito, who is world-renowned for his pioneering work on MTM-based (mid-tweeter-mid) loudspeaker configurations. The original THOR transmission-line design was published in May 2002. For this online publication, audioXpress kept the original article unchanged, which has since been updated with availability of the original Madisound/SEAS kit and the publication of a complete kit project on the SEAS website.

In this much sought after modification project, Nelson Pass rekindles his desire for the JBL L300 Summit loudspeakers and completes a renovation. As he explains, “it is not a trivial task to improve on original JBL design." "I think I’ve managed to respect the JBL legacy while tweaking the sound to reflect the tastes of the 21st century.” Article originally published in audioXpress, January 2012.
