Yamaha SPS-10000 (1987)
The Yamaha SPS-10000 is a speaker stand. It is not a speaker. It is the dedicated floor stand for Yamaha's flagship NSX-10000 loudspeaker, released in 1987 as part of the company's 100th-anniversary Centennial Series. At ¥200,000 per pair, it cost half as much as the NSX-10000 speakers themselves (¥400,000 per pair). Yamaha clearly took the platform under its top speaker seriously.
The stand is built from African padauk, a hardwood dense and fine-grained enough to be used for marimba keys. Yamaha's woodworking shop shaped it into four legs with an airfoil cross-section. The idea was to keep standing waves from forming in the stand as sound waves propagate around it. The geometry was also matched to the NSX-10000's round baffle radius to eliminate diffuse reflections at the stand's edges. Each leg is finished in American walnut with an open-pore finish. At 14.5 kg per stand, the pair added a lot of mass, bringing each NSX-10000 to 68.5 kg total with the stand installed.
Documentation on the SPS-10000 is thin. Nearly everything known about it comes from Japanese database listings and a handful of auction records. No independent period reviews have surfaced, and no production end date is recorded. The sources agree on dimensions of 446.5 mm wide × 250 mm high × 367 mm deep, a weight of 14.5 kg, and the 1987 release. The Vintage Knob, in its coverage of the NSX-10000 system, lists the SPS-10000 as the optional "4-legs carved hardwood stands" for that speaker.
