NAD broke into the speaker world briefly and had these produced by the same company as ADS if you look, you can see the similarities to the L990 series the cabinets are in fair condition. One grill needs to be repaired at one point the grill was glued onto the speaker see photo the woofer is not damaged that is residue from the glue I did not want to damage the driver by trying to clean it as it does not affect the performance,the sound quality from the speakers is absolutely amazing. They are very rare and hard to find.
