Abacus C-Box 4 (pair)
Description
ABOUT THE MONITORS
The ABACUS C-Box 4 active 2-way monitor is the larger sibling of the high-end audio monitor C-Box 3. Compared to its predecessor, it offers higher volume levels and deeper bass response. This model is suitable for smaller stereo configurations, nearfield monitoring, or playback in combination with a subwoofer. The enclosure volume of this model is approximately 3.7 liters. Inside, it features a 5.75" woofer paired with a 1" tweeter, an Abacus Dolifet power amplifier, and an active crossover. The C-Box 4 is also equipped with RCA input connectors, volume and bass frequency adjustment controls, and a 3/8" thread for stand mounting. The monitor operates within a frequency range of 32 Hz to 20 kHz (-6 dB) and is available in several different color finishes.
The ABACUS C-Box series offers some of the most compact monitors for high-end listening. With these, you can get top-quality sound even in limited spaces, whether it’s on your desk, around your TV screen, or in a study. Despite their small size, the low-end frequency response of these monitors extends down to 32 Hz, where the special circuit technology and closed design contribute to a completely natural bass presentation. While the C-Box 3 is sufficient for a desk or TV sound setup, the C-Box 4 handles full-fledged listening situations and can be used in combination with a subwoofer or in a surround setup.
Thanks to the extremely short and compact signal path inside the C-Box monitors, only a few active and passive components are used in the design, significantly reducing the monitors’ self-noise levels. All C-Box series speakers feature 1" ring tweeters that give them their distinctive appearance and are ideal for nearfield listening due to their properties. The C-Box speakers use bass woofers from Wavecor, which deliver excellent performance, and their fiberglass-reinforced membranes provide sufficient strength for outstanding bass reproduction. The C-Box 3 and C-Box 4 are practically identical models from a technical standpoint. The smaller model features a more compact and powerful neodymium magnet, while the larger model uses a more powerful ferrite magnet.
