A revolutionary subwoofer that has evolved in terms of performance, function, and design, from the previous award-winning model which consecutively received the highest rating from Japanese and overseas audio magazines.


Eclipse has introduced unique state-of-the-art technology including its R2R Twin Driver structure, which reproduces voluminous bass sounds at high response speed with a minimized delay. Eclipse is in an ongoing pursuit of excellent damping properties so that users touching the enclosure will not feel any vibration at all. Furthermore, the product is provided with seven-layers of piano black coatings to produce both purer bass sound reproduction as well as visual beauty.
Eclipse focused on the delay caused by subwoofers, and aimed at accurately reproducing the sound signals recorded in music and movie software. If bass sounds are reproduced accurately, the clear and accurate reproduction of full orchestral timpani and gran casa sounds, which cannot be attained by conventional subwoofers, will be possible with the timing as intended by the conductors. The reproduction of bass sounds at a high response speed in stereo or surround mode, which top artists in the world appreciate, will make it possible to refine the entire sound field, more closely reflecting the ideal listening environment.
Speaker Units:
A large speaker unit is traditionally required to reproduce rich and powerful bass sounds. If a larger speaker is used, the area of the speaker that presses the air and the weight of the diaphragm will increase, thus making it difficult to control the movement of the diaphragm quickly. Therefore, Eclipse's subwoofers do not adopt large-diameter speaker units. Instead, they use original speaker units that are comparatively small in diameter so that they can be driven at high speed. Furthermore, each model uses two speaker units, thus achieving the reproduction of bass sounds and high power that is equivalent to large-diameter speaker units.
Aluminium Shaft Coupling:
In order to drive speaker units at high speed, strong bases are required to secure the speaker units. For example, Eclipse's speaker units are secured to ground anchors to form tough bases. In this instance, Eclipse's subwoofers connect two speaker units facing back to each other with an aluminium shaft instead of ground anchors. The two speaker units are driven in-phase, the generated reaction force of which forms a strong base in place of a ground anchor.
Floating Structure:
If speaker units are mounted directly to an enclosure, the vibration of the speaker units may cause unwanted sounds that do not exist in the original sounds. Eclipse uses special material to suppress vibration and places two speaker units in an enclosure. Furthermore, the supporting section of the internal aluminium shaft uses a special material to cancel any vibration. This structure not only minimizes unwanted vibration transmitted to the enclosure but also maintains the interior of the enclosure airtight.
High-output Digital Power Amplifier:
Eclipse adopts an ICEpower-made high-output, digital power amplifier in order to extract all the potential out of the two small diameter speaker units which are designed to achieve a wide-range sound reproduction at high-response speed. The incorporation of the digital power amplifier enables the downsizing of the internal circuit and results in high-efficiency energy conversion thus solving various issues, including problems in the occupation of internal space and heat dissipation. The digital power amplifier has improved the 'bulk ratio' of the subwoofers while keeping high linearity at maximum output, thus achieving the reproduction of bass sounds with sufficient margins.
LPF Bypass Function to Send Signals Directly:
A low-pass filter (LPF) for music signals is one of the causes in delaying music signals to subwoofers, and plays an important role working as a treble blocker while allowing bass sounds to pass the LPF. Therefore, a slight delay in low-range signals will result. Furthermore, devices, such as AV amplifiers and subwoofers, use LPFs, and a delay in bass sounds will become significant when music signals pass through a number of LPFs. In order to solve this phenomenon, Eclipse's subwoofers incorporate an LPF bypass function. In the case of reproducing subwoofer channel signals, including Blu-ray music signals, through the built-in LPF of an AV amplifier, a delay in bass sounds can be minimized letting the sounds bypass the LPF on the subwoofer side.
Dual Control Function Allowing Versatile System Set Up:
Eclipse's subwoofers incorporate versatile input and output terminals to support a variety of stereo and sound systems in combination. In addition to line (stereo) input and output terminals, speaker level input and output terminals are provided, thus connecting to 2.1- and 5.1-channel systems as well. Furthermore, the input and output terminals are divided into two blocks, each of which allows independent volume and LPF level adjustments. This dual control function with two control blocks makes it possible to construct versatile systems, including AV and stereo amplifiers, eliminating equipment limitations with dramatic operability improvements.
