OOOOooh, nice to see those ALS-40s in the photo. Brings back fond memories.

(unfortunately don't have room for the Transmission lines, but that's a cracking price)
 
Were you not so far away, I would have these off you for sure! for anyone else, here is a quick summary....

Do not be fooled by their age / appearance, the laws of physics have not changed since these fine monitors were designed, and fine would be a vast understatement, good luck with the sale m8.
 
cheers.

I'm not actually sure they are Mk 3s now, as having taken the b-139 out the damping used is made of what looks to be fibreglass.

and on the Mk3 literature on the IMF site it says

"The MONITOR III is a "fourth generation" refinement of the now famous transmission line principle (first generation, the stuffed line of 1965; second generation, the tapered line of 1968; third generation, the "flow through" damping of 1969). The "fourth generation" is the development and use of "honeycomb mesh damping" (see illustration), which effectively doubles the absorption area of the filters and increases the acoustical path length"

Any ideas?

If the first generation (stuffed line) is just a tx line with fibreglass jammed inside it, what are the 2nd and 3rd gen?
 
Hello Jimmy,

What would postage within the UK be for those large IMF's , can you confirm they are in full working order, and is the midrange the original ?

Regards,
Steve
 
They are in good condition. there are a few scratches here and there but certainly nothing major. They are also in good working order - I recently demo'd them to a potential buyer and he couldnt find any faults with them (other than the fact that they wouldn't fit in his room!) I wouldnt know if the mid is original. Do you mean original in the sense that it is the one that was supplied with the speakers when they were first purchased. Or just of the original type. It is the correct type of Kef mid but as to its origins and age (as with all of the drive units) I have no idea, although they do all work perfectly.
I dont think postage is really an option. I was hoping for a local buyer and would be able to deliver them within the local area, but it would be a nightmare packing them and probably cheaper to hire a small van and come and get them. If you want to get a quote for a courier allow 50 Kgs each.

Regards

Tom
