These heavy speakers from the 70's are checked and cleaned. They sound great. tested thoroughly. Description The DM2 is a precision three unit monitor loudspeaker employing highly developed units with B&W acoustic line loading giving extremely low distortion and exceptional frequency linearity. This loudspeaker fully meets professional monitor requirements and is capable of most realistic reproduction of both speech and music programme material. Because of its low distortion, wide and balanced frequency response and freedom from colouration, it will be analytical and may well reveal faults in programme material and defects in ancillary equipment which an inferior product would mask. Let me introduce ourselfs. We are from J&R audio. Two 'hobbyists' who have been saving and repairing 'older' audio for many years. A bit of a hobby that got out of hand. With around 800 items, we think it is time to reduce the collection. Many products can be sold for a social price. And this despite our professional working methods. Service on all our products is often provided by ourselves, but also by our extensive network of many professionals with whom we have been working happily for years. Components that need to be replaced need to be replaced, strings need to be replaced in most cases, just like the lighting. In most cases, LED lighting is built-in. It is possible to provide a warranty for many products. Ask for the possibilities. We also polish the covers of record players and spray the outside of equipment or the innovative paintwork of your speakers. We hope to make many people happy with nice equipment in this way. We put the proceeds into improving tools and equipment. And so we hope to continue to improve and to be able to continue this work, which originated from friendship and hobby, for a long time to come.
