S-BACH H-12F adopts loudspeakers 2 frequency division 2 unit/2 way 1 order/ two hole front inverted design.

The front two hole leading phase design retains the classic practice of coaxial loudspeakers, and takes into account the placement characteristics of large speakers to the maximum extent, and solves the contradiction between the movement and positioning of the large box.

The speaker adopts an adjustable frequency divider design, the crossover point is adjustable in three steps, and the tweeter gain is adjustable in five steps..

The adjustable frequency divider is a dedicated HiFi circuit developed by S-BACH acoustic engineers for the cabinet. It uses ceramic axial HiFi audio resistors, American imported oxygen-free copper inductors, and MKT axial pure copper pin thin film hi-end capacitors.

S-BACH acoustic engineers developed an advanced 1.75-inch diaphragm tweeter unit with an exquisite matrix structure.

The small horn tweeter matrix structure design is completely out of resonance with the mid-woofer unit. The matrix and horn design features of the tweeter unit.

12 / inch mid woofer unit: the paper basin is used as the basic material of the unit, and easy driving is one of the biggest advantages of the paper basin.

High density board imported from Australia is used in the whole box. The physical characteristics of the board can disperse and absorb the invalid bending wave in the acoustic cavity and the box resonance. The design of the leading two holes completely integrates the frequency resonance principle of aerodynamics, and enhances the density and performance of the original low and medium frequency by multiple amplification.

The material selection and color matching of camphor board are made of matte North American black walnut bark, regardless of the cost, and the box camphor board is made of expensive matte golden poplar solid wood + gold alloy ornament
