Passive subwoofer for ARION 10 line array system.

SL 212B is a low frequency speaker with brand new shape and structure design as well as advanced paint spraying techniques. It is combined of two 12'' LF speakers. The 100 mm flat aluminum and TIL material bracket enable full heat radiation. The RMS of speaker can reach 900 W and short term peak power reach 1800 W.

The design of parallel magnetic circuit can reduce the odd harmonic in the LF speaker to the fullest extent.

The cabinet of SL 212B is made of 18 mm thick plywood with streching resistance up to 4500N. The wedge structure frees the cabinet from any nails. The paint on the surface has high resistance to abrasion. The invertred bass design wich provides best sound quality is used in SL 212B. Also the phase reversal tube is improved by reducing the disturbance to the low frequencies.

Thanks to the powder spraying techniques, the grille of SL 212B has high resistance. The inner side of the grille is padded with cotton to protect it from rain.

SL 212B is mainly applied in meeting rooms, large multifunction hall, auditorium, churches and mobile performances.
