The L26RO4Y subwoofer. Developed in cooperation with Linkwitz Laboratories in Corte Medera, California, the L26RO4Y will see its first application in two new versions of the highly acclaimed Linkwitz ORION open baffle loudspeaker. The L26RO4Y substantially improves the ORION's bass performance and dynamic capabilities. We at SEAS are also very proud that the ORION loudspeaker now uses all SEAS drive units!

 "There is more to a woofer than its published TS small signal parameters and X-max, derived from mechanical measurements. In the Orion's open baffle, a woofer operates in the large signal domain; and its distortion, dynamic stability and limiting behavior determine the sound. An open baffle is the most demanding and difficult environment for a long throw woofer." -- Siegfried Linkwitz:

To meet these stringent demands, the L26RO4Y subwoofer builds upon the already excellent chassis, magnet system, cone, and surround of our L26ROY. An all new FEA designed spider and 4 layer voice coil wound on a stiff glass fibre former have been employed, resulting in a driver with ultra long throw, very low distortion, and extremely stable mechanical operation under all conditions; including open baffle systems.  The low Qts and Fs are ideally suited for active open baffle bass systems, but the L26RO4Y can also produce excellent results in enclosure based subwoofer and multi-way  systems.

• Extremely stiff and rigid aluminium cone gives tremendous bass precision. The cone and the long throw low loss rubber surround show no sign of the familiar cone edge resonance and distortion associated with soft cones.
• Lead-out wires symetrically stitched to the spider to avoid resonances. Total suspension designed to assure stability for extreme excursions.
• 4-layer, extremely long, high temperature voice coil wound on an glassfiber voice coil former gives a high power handling capacity.
• Cu-cap around the pole pieces reduce non linear and modulation distortion and increase overload margin.
• Extra large magnet system provides high efficiency and low Q.
• Extremely stiff and stable injection moulded metal basket keeps the critical components in perfect alignment. Large windows in the basket both above and below the spider reduce sound reflection, air flow noise and cavity resonance to a minimum.

The specifications suggest using this woofer with the matching passive raditor SL26R.   You could also use this woofer in either a sealed box or open baffle, but you will need to use an equalizer or bass boost to extend the low end.  Using on in 0.6 cubic foot sealed box without any boost will give you an F3 of about 50Hz.  Using this sealed box in a vehicle with 6dB of cabin gain gives you an F3 of about 25Hz!
