monolit ABACUS C-Box
The ABACUS C-Box 2 is probably the most compact solution for high-end audio on a table top, for flat screens, in offices, in kitchens or simply anywhere, where great sound is needed in a confined space.
In the ABACUS C-Box 2, the amplifiers operate with an active frequency crossover. Because of the special ABACUS circuitry, the frequency response goes down to 35Hz. Combined with concrete cabinets from monolit-speakers these loudspeakers become perfect.

  • cabinet: ca. 1,6 l, closed box
  • mid-woofer: 100mm/4” Cone
  • tweeter: 25,4mm/1”-neodymium-ring-radiator
  • frequency response: 35 to 20.000 Hz linear
  • input: line via RCA

In the LED and LCD era, computer monitors and TV screens show a tendency of becoming ever flatter. Unfortunately, sound quality is also getting flatter. There are plenty of computer loudspeakers out there, however almost all of them produce rather mediocre sound.
The ABACUS C-Box is a very compact, high-end hi-fi solution for your desk or for your TV.
If intense sound is not needed, the C2 version of the hi-fi system provides renewed harmony
in spaces that are not too large. The C-BOX also has its place in a multi-channel or surround sound system. And in the field of sound engineering, the C-BOX turns out to be a perfect nearfield monitor.

Test-Fazit: Abacus C-Box 2 – Aktiv-Lautsprecher

“Die C-Box 2 ist im Desktopbereich das Beste, was ich bisher zu Hause hatte. Sie vereint die für einen Nahfeldmonitor geforderten Eigenschaften (neutrale tonale Abstimmung, gute Feinauflösung und stereofone Ortungsschärfe) mit einer involvierenden Spielfreude sowie guter Fein- und Grobdynamik. Auch im Heimstudio und als Musikerlautsprecher leistet sie sehr gute Dienste…”
