Low frequencies are very important for our sound environment. Add accurate, low bass notes and the realism of the reproduction improves significantly, with a sound that envelops the listener, bringing weight, body and musical authority.

But reproduction below 80 Hz has its own set of rules. Relatively speaking, these are "slow", long wavelength signals. For example, a 30 Hz tone has a wavelength of over 11 meters. Generating convincing low frequencies means moving a lot of air, which requires a large diaphragm with a long stroke and a powerful motor to produce realistic levels.

The diaphragm of the C18 low bass module has a very large diameter of 460 mm and is capable of +/- 10 mm displacement. That allows the driver to move an air volume approximately nine times as great as a comparable 8” high-end bass driver.

This very large diaphragm area allows the C18 to move enough air to produce a musically convincing bass note from a very short stroke, allowing for fast, agile and dynamic low bass reproduction down into the subsonic range. The air is also compressed less by the shorter stroke, which allows the bass to breathe more naturally and deliver greater physical and musical impact.

Did we say the C18 has a powerful motor? The driver has a 150 mm voice coil and a high power handling of 1,600 watts (AES2012 standard). This gigantic motor structure achieves superior, compression-free dynamic reproduction even at very high levels, with a superior power factor and minimal thermal compression. Because we cannot actually locate low frequency sounds below 100 Hz, it is possible to place the C18 low bass module anywhere in the room. We have kept the C18’s enclosure compact at 70 liters and the overall depth deliberately slim at 28 cm, so that it can be easily placed against walls, in the corner of the room or concealed behind the sofa.

Internal braces stiffen and stabilize the cabinet. In addition, the front and rear baffles are firmly connected to each other by the massive metal frame of the 18-inch driver. Three elastomer damping elements provide additional reduction of vibration in the cabinet structure.
