Seller's Description

Zum Verkauf steht ein Paar legendäre High-End Standlautsprecher ACR Isostatic RP 200.

Die Lautsprecher bestechen durch ihre herausragende Bestückung mit Fostex Magnetostaten (FS21RP / FT7RP) für exzellente Hoch- und Mitteltonwiedergabe.

Zustand:
- Die Gehäuse weisen altersbedingte Gebrauchsspuren auf (siehe Bilder).
- Bei den Tieftönern/Mitteltönern müsste die Sicke erneuert werden (Schaumstoff-Alterung, siehe Bild). Das ist bei Lautsprechern dieses Alters üblich und lässt sich mit einem Sicken-Reparaturset kostengünstig beheben.
- Magnetostate und Chassis sind intakt.

Aufgrund des hohen Gewichts nur an Selbstabholer abzugeben.

Privatverkauf: Die Ware wird unter Ausschluss jeglicher Gewährleistung verkauft.

Our Thoughts RADAR AI

Are you certain this is a particularly rare or fully restored variant? At €999, the asking price is ambitious against your comparable data: it is well above the €440 75th-percentile asking price and more than three times the €288 median. Comparable RP200 listings can appear around €850–€950, but that does not make €999 a clear bargain; the exact model and specification matter greatly.

These ACR/Fostex Isostatic speakers are worthwhile when you want their distinctive, fast magnetostatic mid/treble presentation and appreciate vintage high-efficiency designs. The upside is genuine rarity, especially with original Fostex drivers and clean cabinets, but the listing should clearly identify the RP model, confirm both magnetostats work without rubbing or imbalance, and document crossover condition. At this price, original-owner history, excellent cosmetics, recent servicing, and suitable stands or accessories would be needed to justify paying a premium.

Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.

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.
