Sky Audio – 10" Subwoofer: Ultra-precise, passive

The Sky Audio 10" subwoofer is the ultimate addition to the Sky Audio Verdade II monitoring system. As a passive subwoofer featuring a high-quality 10" aluminium cone, it not only delivers higher sound levels but also extends the lower cut-off frequency down to 25 hertz, ensuring powerful bass reproduction. Thanks to its identical cabinet size, the subwoofer blends seamlessly into the design of the Verdade II, forming a harmonious whole both acoustically and aesthetically.

The subwoofer is housed in a sealed enclosure, which ensures accurate bass reproduction. Its construction minimises unwanted resonances and enables precise sound reproduction. Furthermore, the enclosure is reinforced, which increases stability and further improves sound quality. Perfect for professionals seeking a deeper dimension of sound.

Specifications:

• Passive high-end subwoofer

• Sealed enclosure

• 10" aluminium cone

• Height: 43 cm

Abacus 20-120 Dolifet

With the fourth generation of this long-established model, ABACUS presents the first unit to feature ‘Dolifet Technology’ (Drain-Output Load-Independent Field Effect Transistor). A completely new control system, power supply and signal processing have been combined with a new variant of the tried-and-tested ABACUS circuit and housed in a new chassis.

The result is an amplifier that is unrivalled, offering even greater control over loudspeakers whilst delivering further enhanced performance. The automatic switch-on function and balanced inputs make it even more versatile and user-friendly.
