FS/... IMF Super Compact Speakers (restored)
My lovely IMF's are up for grabs. Cabinets, xovers and main drivers(Kef B200) have been restored/ replaced. Elcap caps in xovers, and 2 kef main drivers. Look and sound great, and only for sale as I have too many speakers tbh so some will have to go. They are REDUCED to £180 including delivery ..I have new carboard so will custom make boxes if needed so they are safe.
These don't come up very often ......

With the Super-Compact, enclosure size is sufficient to accommodate the use of a bass unit with a free air resonance around 25Hz. The drawing illustrates the resistive loading conditions which, 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 is similar to those we used in our Studio TLS 50 and ALS 40 loudspeakers.
The decision was also made to adopt the same complex and expensive crossover and mirror image configuration as in these larger models. This results in two important advantages. The in-line crossover network has been developed as a no compromise optimum filter for the drive units employed and as such, provides the minimum of colouration and thus the maximum sense of acoustic transparency. Secondly, it ensures that the phase and dispersion characteristics of the SuperCompact are substantially identical to those of the TLS 50 and ALS 40. Thus all three models are compatable for four-channel applications. Research demonstrates that dissimilar loudspeakers cannot be used for four channels any more than unmatched speakers are acceptable for stereo. Even choosing all loudspeakers from the same manufacturer is no guarantee of compatibility unless the speakers have the same phase relationship throughout the range and a substantially similar integrated performance. With an eye to the future, IMF in their Super-Compact have ensured this compatibility and anticipate that many of these speakers will compliment IMF Studio or ALS 40 loudspeakers for rear channel information. Meanwhile the prospective customer can purchase now without .fear of pending obsolescence.
We have said very little about the sound of Compacts, which in a way is a good thing for both have little of the obvious 'hi-fi' qualities about them. 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. Although of moderate efficiency, 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. The speakers are worthy of the best amplifiers and indeed the finest ancilliary equipment. We invite you to audition the IMF Compact II and SuperCompact loudspeakers against others beyond their size category.
