Yamaha NS1000M legendary Monitor loudspeakers, refurbished paintwork and WBT terminals. Rewired to bypass tone controls and pinch connectors replaced with German WBT brand speaker terminals for a purer sound. These speakers are known internationally for a tight and massive bass response, with a fast and accurate high and mid range from the use of the rare metal Beryllium in the forming of the tweeters and mid range drivers (the worlds first manufacturer to do so). They are easy to drive - see the numerous reviews on line. Very good condition generally due to refurbishment of paintwork; note there are some small usage scratches underneath the speakers where they connect with the stands and a dent to rear corner woodwork of one speaker not visible from the front. The backs of the speakers are the standard black painted chipboard (not designed to have the same finish as the front and sides, as with most speakers from this vintage era) Original Phillips type Driver fixing screws replaced with top quality stainless steel Allen bolts to increase rigidity of the driver fixing to the cabinet.
