These are an excellent pair of speakers built by KEF, and are in very good condition. There are some slight cosmetic blemishes, but nothing major. They have been used in a smoke free house with no pets. They still sound excellent, and should have many many more years of use in them.Here is the information from KEF:
Monitor Series RDM2 (1996-2000)
RDM2 was a compact two-way reflex system using a long throw version of the 165mm (6.5 inch) Uni-Q array from the Reference Series Model 100. It produced a clean, detailed and consistently smooth sound – a prerequisite for extended listening sessions. The reflex loading allowed a higher sensitivity and output capability compared to the RDM1 and both systems could be used equally well when mounted on their sides, for example, on a monitoring desk, due to the symmetry of the Uni-Q radiation pattern.
