Rectilinear 3's: Is it worth upgrading tweeters???


Does anyone remember the Rectilinear 3's??. It was a floor standing speaker considered almost hi-end in the early 1970's. I ask, because a friend has inherited a pair in very good condition, but has no interest in them; so, I may buy them because they are audio "classics" They sound very good for a 30 year old speaker but are also a little slow, and imaging is just average. Anyone possibly have a pair of these speakers in use in their system?? I would like to hear from you, especially if you know of any "upgrades" available that can be made to improve the imaging, but still perserve the speaker's neutral sound character. Thank you, SJ

You are considering a neat pair of speakers. For my money they are not worth upgrading. If you were to consider an upgrade the first candidate would be the Phillips midrange unit complete with wizzer cone. Pretty peaky. Then maybe the wiring and crossover components. Another problem with all of this upgrading is that you take a balanced speaker like the 3 and rapidly bring it out of balance. Not good. I think that the cone tweeters are actually one of the strongest points of the design. Some designers are currently rethinking the whole dome tweeter thing and we may see more cone tweeters and paper cone drivers in general. If you like the sound of the 3s buy them and enjoy them, but don't think that you can make them into a much better speaker.
Not much you can do without changing the entire speaker into something it is not. Enjoy them for what they are.
I owned a pair of Rec 3s in the 70's. If my memory is correct the original midrange did not have the whizzer cone. When a room mate blew the mids in mine the replacement midrange DID have the whizzer and sounded distinctly inferior to the original. You might look and see which is there...if the original is there don't over-drive the speaker.
Good Luck
