The demonstration room at Dong Thanh Hoa Phuc features products such as FM 255 MK II R, FM 115 and FM 411 MK III. The 'pièce de résistance' is the ARC circuitry of the FM 266 MK II RC which eliminates standing waves and room resonances, achieving superb improvements. Now added to the collection is the '1' Series, consisting of FM 123, FM 133, FM 155 MK II R and a pair of the amazing FM 108 MK II.
