Design

Scythe Kro Craft Speaker Rev.B (SCBKS-1100)

The speakers Scythe SCBKS-1100 have classic design. The case of speakers is made of MDF and covered with black vinyl film. The use of this material must have a good impact on the quality of the sound, because it is quite inert and absorbs sound waves.

In terms of shape the speakers Scythe Kro Craft Speaker Rev.B are extended upwards. Large woofer is placed in the bottom of the front panel. Concave metal diffuser with diameter of 100 mm is attached to the suspension of a soft rubber material that provides sufficient freedom of travel. Soft plastic tweeter is placed on the top.

External examination of product revealed no defects found in other products in this price range. That is defective seams or glue stains were not found. Unfortunately, the speakers don’t have rubber legs for mounting on a work surface. On a large scale, this is not the worst thing that you can find.

Phase inverter in the form of slots is located at the top rear of the case. For more effective neutralization of noise the housing has an additional partition. Rear placement of phase inverter does not allow to put the speakers close to the wall, which can cause some discomfort when placing them on the table. To be clear it is possible but, but in this case you will have some distortion of bass. On the other hand, if it was placed in the front, it would increase the vertical dimensions.

Input signal is realized via gold-plated screw terminals, where you can tie a fairly thick wire. The set of Scythe Kro Craft Speaker Rev.B contains wire with a thin cross section, so foe higher quality of sound it is recommended to buy thicker cables.

The internal structure is organized on a high level. The dampers are made of polyester, which is a good sound absorber.

A significant innovation in the design of Scythe Kro Craft Speaker Rev.B is increased magnet woofer with diameter of 8.4 mm that improves the playback medium and low frequencies.

Digital amplifier Scythe Kama Bay AMP 2000 Rev.B (SDAR-2100) on the chip Yamaha YDA138 at relatively high performance has a rather low level of power consumption.

The low frequency filter is represented by one non-polar film capacitors. This is good news for music lovers who can fix the smallest noise and harmonic distortion of sound section. In terms of characteristics affecting the clarity, non-polar film capacitors are superior of electrolytic.
