Iconic Vintage Monitors

These 1970’s British classics are in excellent physical condition (see close-up pictures) and full working order. One tiny little ding on the top of one speaker (see picture 3), but that’s about it.

Just in case you don’t already know, these contain the same drive units as all LS3/5a 15 ohm enclosures (KEF B110A bass/mid driver and KEF T27 treble driver). Therefore, in terms of sound reproduction, they are quite similar to an LS3/5a but with slightly more generous bass response. The crossover is not as sophisticated as that of an LS3/5a but it does offer fuse protection. The LS3/5a offers variable treble responses by way of 5 links in order to increase or decrease treble by + or – 1dB. The JR149 offers a variable treble response by way of a potentiometer.
