Seller's Description

Ich bite zwei der legendären Fostex D 450 (hier als ACR gelabelt) an. Sie sind in einem sehr guten Zustand (mit ein Paar Kratzern auf dem rückwärtigen Gehäuse) und waren bis voriges Jahr in einem ACR- Radialhorn (220er) gelaufen. Die Schutzgitter vor den Treibern habe ich entfernt, bringt im oberen Bereich eine hörbare Verbesserung. Der Gleichstromwiderstand beider Treiber beträgt 7,3 Ohm, gemessen mit Fluke-Multimeter. Abholung ist möglich genauso wie Versand. Hierbei ist zu geachten, dass die Treiber ganz schöne Brocken sind und ich hier eine etwas aufwändigere Verpackung herstellen muss. Bei Fragen wie immer Mail.

About Fostex

Fostex emerged in 1973 as the branded consumer and professional division of Foster Electric Co., Ltd., a Japanese loudspeaker manufacturer founded in 1949. Established to bring Foster's high-quality speaker components directly to dealers and customers, Fostex quickly gained international recognition through innovative products like the T20RP headphones and 6301 studio monitors. The brand's foundation rests on Foster's position as one of the world's largest OEM loudspeaker developers, employing tens of thousands across multiple countries and manufacturing millions of speaker units monthly.

The company built its reputation across three interconnected product categories: professional studio equipment, consumer headphones, and powered monitor speakers. Fostex became particularly renowned for pioneering RP (Regular Phase) technology, which delivers clear sound with high sensitivity and wide dynamic range—a signature that defines their headphones, microphones, and speaker designs. Beginning in 1978, the brand expanded into professional speaker development, eventually introducing the PM series of powered monitors and establishing itself as a trusted choice for recording studios, broadcast facilities, and serious home listeners.

Fostex occupies a distinctive middle ground in the audio market: neither ultra-premium boutique nor mass-market consumer, but rather a respected specialist brand with deep professional credentials. Their products appeal to recording engineers, studio owners, and discerning hi-fi enthusiasts who prioritize accuracy and reliability over luxury positioning. The 6301B monitor remains an industry standard after decades in production, while the T20RP headphones maintain popularity among studio professionals—testament to Fostex's enduring reputation for sonic integrity and engineering excellence.
