Seas XM004-04 L26RO4Y UPGRADED REPLACEMENT for L26RO4Y D1004-04
Linkwitz Orion 3.4 & Orion 3.5 10” SubWoofer. Discounted Full Orion Driver Sets and information pages from Linkwitz Labs are available here.
“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.
Design features include:
Lead-out wires are symmetrically stitched to the spider to avoid resonances. Total suspension is designed to assure stability for extreme excursions.
4-layer, extremely long, high temperature voice coil wound on an Glassfibre voice coil former gives a high power handling capacity.
Copper cap around the pole pieces to 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.
