Unique opportunity to get a pair of these Phillips 545 MFB studio monitors. Not seen very often in the USA. This model speaker has a long history and were the model type used in mixing Pink Floyds "The Wall" amongst countless other epic recordings. I had these in my studio many years ago in the listening lounge.They are a 3 way self powered tri amp design. There were only 1000 of these made and were very expensive at the time in the late '70's when they were manufactured. Collectors still pay thousands for these. There is a lot of info on these on the internet so do your research first before you respond to me if you are serious. Thanks.
