Seller's Description

ONLY SET ON REVERBOne pair Sansui SP300 speaker set.EXTREMELY RARE and in very good all around condition given their age (58 years?)Made in Japan for only 2 years, 1968-1969. Probably the rarest of all Sansui speakers. These speakers were not available in the United States.My Dad acquired these while stationed on Midway Island in the Pacific Ocean in 1968 and had them shipped via the military back to the United States when he left the island in 1970. These are all original and have seen little use. They've been stored in a climate controlled environment for all these years.As die-hard audiophiles will attest, these speakers were not made for powerful output but rather for precision of sound. Read what few online reviewers have to say about these. It's because of the incredibly high decibel sensitivity that these speakers possess. These Sansui speakers are some of the most efficient speakers ever made.Specs from the internet:3-Way, 4-Speaker, Bass Reflex System, Floor Type UnitFor low band: 30 cm cone type For Middle Range: Horn Type For High Frequency: Horn Type x 2Frequency characteristic 35 Hz to 20000 Hz Max Input 50W Conservative Rating, Impedance8 ΩOutput sound pressure level 104dB/W.Crossover frequency 1000 Hz, 6000 Hz (12dB/oct.)

About Sansui

Sansui, a pioneering Japanese audio brand, traces its origins to 1947 when it was founded in Tokyo by brothers Sakurai and Shunichi Yamamoto. Emerging from post-war Japan, the company quickly established itself as an innovator in consumer electronics, leveraging precision engineering to craft components that rivaled Western counterparts. Its heritage is rooted in the golden era of hi-fi, where Sansui's commitment to sonic purity helped define Japan's rise as a global audio powerhouse.

The brand excelled in a broad spectrum of hi-fi categories, with particular renown for its integrated amplifiers, receivers, and tuners that delivered warm, dynamic sound. Sansui also produced acclaimed speakers, turntables, cassette decks, and later digital converters, emphasizing robust build quality and innovative features like direct-coupled circuitry for low distortion. These products catered to audiophiles seeking balanced performance across analog and early digital domains.

Today, Sansui holds a cherished position in the vintage collector market, revered for its mid-to-high-end gear from the 1970s and 1980s—icons like the AU-series amps remain sought after for their musicality and reliability. While no longer a frontline manufacturer, its legacy endures among discerning buyers restoring classics or hunting timeless performers, blending nostalgia with enduring value.
