Offered is „RSPM MKIV“ by IMF as second-hand device from the category „Standing Speaker“ on audio-markt.de - the online market place for high-end. The advert with the number 3179742288 ends on 17.11.2026 at 17:57 o'clock.
This is a buyer’s market for this piece at the moment: at €2,400, this sits well above the €859 75th percentile and more than five times the €479 median, so it’s an ambitious asking price rather than a bargain. Even allowing for strong condition, the price is high enough that it needs something exceptional behind it to justify the premium.
The upside here is that this is a respected IMF loudspeaker with the kind of scale, imaging, and bass authority that keeps serious vintage listeners interested. A clean good-condition example can be very appealing if originality is intact and the cabinetry and drivers are healthy, but at this level I’d want proof of recent servicing, original parts, and complete accessories/documentation before moving fast.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
IMF is a classic British hi-fi name founded in 1961, originally tied to Irving M. “Bud” Fried, a transmission-line loudspeaker advocate whose initials gave the brand its name. The trademark was registered at the suggestion of Saul Marantz, and the company became associated with advanced audio reproduction rather than a broad consumer-electronics lineup. Its strongest historical identity is rooted in the UK speaker scene, with a transatlantic connection to the American market.
IMF is primarily known for loudspeakers, especially its transmission-line designs such as the Reference Standard and other monitor-style models. The brand name has also appeared in connection with a wider range of audio components in its early history, including cartridges, tonearms, amplifiers, and other supporting hardware, but speakers are the core of the IMF story. It is not generally known as a maker of modern DACs, headphones, or cables.
In the market, IMF sits firmly in the vintage-collector and enthusiast category rather than mainstream mass market. Its reputation rests on engineering credibility, large-scale monitor speakers, and a distinctive sound that appeals to serious hi-fi buyers and restoration-minded collectors. For today’s shopper, IMF is best understood as a niche heritage brand with historical importance, not a current broad-line audio manufacturer.
