Maintenance has been completed! It is a model that uses the Siemens rare Coaxial unit C72233-A10-A7, 2 machines on each side, for a total of 4 machines. Siemens is a representative of flat baffles, but the rear open type adds the fullness of the low frequencies and plays an impeccable and wonderful sound quality. It is an indescribably comfortable speaker with a clear sound quality but an excellent balance without being tough (Katsuji Hiura)
