Cambridge Audio R40 speakers. in near showroom condition - Factory built models - NOT the kit...
3 Way ... -- we've recapped the crossovers, fully restored. 
And replaced the old tiny screw terminals with banana terminals for more appropriate method of connectivity.
I think these are the best speakers of this generation (1971-74).  Clear, no nasality in the midband, controlled, accurate  bass. ... I test with Catherdral organ, Orchestral, Chior and Pink Floyd.
