The perfect match
If you consider building a vintage system, these are units we recommend to get the best out of this product.
IMF Super Compact speakers
IMF stands for Irving "Bud" M. Fried, audio pioneer and classical music lover that founded the anglo-american IMF company in 1968.
The original IMF Compact Loudspeakers were a great success. Despite opinions to the contrary, the Compact demonstrated that there is a sophisticated strata of the hi-fi buying public who do not judge the merits of a loudspeaker system on a cost versus size basis. This demands a loudspeaker that necessarily needs to be made at a price, rather than to a price.
With the Super-Compact, enclosure size is sufficient to accommodate the use of a bass unit with a free air resonance around 25Hz. The resistive loading conditions, whilst not impairing the exceptional bass response, damps the system against 'cone weave' from unwanted subsonic signals. The mid-range is isolated in its own short transmission line and this unit along with the tweeter.
Low frequencies are remarkably extended for their enclosures sizes, but are smooth and free from the exaggerations of 'one note bass'. The middle and top has a sense of 'sheen' and continuity - rather than the sound of multiple speakers working in a box. The efficiency is high, such is the freedom from distortion and colouration, that listening at low levels as well as high, gives a sense of balance that reveals all that is worthwhile over a wide variety of programme sources. We loved our sessions with this pair, and can bet that at blind test listening most amateurs will expect a bigger size loudspeaker.
Probably one of the best vintage compact size speaker you can get for your money.
This pair is in very good condition, with good veneer all round and intact grilles wearing the original badges, that were sanitized. You will most of the time these pairs with a consistent issue: the foam around the medium driver is damaged. And this one is just sorted as we fitted new suspensions.
Belonging to a late series, the connectors now are proper, earlier models were fitted with bland screws only. Do note that the yellow foam at the bottom is perfectly factory original, no bedding company material was sourced here.
This pair is still originally matched as exiting the factory after measurement, wearing a unique serial number completed by L and R for Left and Right.
Perfect condition for age, see photo gallery for signs of patina or use.
