3 ECLIPSE TD Innovations That Embody Time Domain Theory
The elimination of undesired harmonics - which was difficult to accomplish in all previous speaker systems - has now been achieved by the "ECLIPSE TD," through the application of 3 outstanding technical innovations. [Figures 4 and 5]

1. Diffusion Stay: A Floating Enclosure
In the most common construction method used for conventional speaker systems, a speaker unit is mounted directly onto a baffle, which forms part of the enclosure. However, this method of construction allows vibrations from the speaker diaphragm to travel through the frame to the baffle, thus creating harmonics and reflected sound waves that are not present in the original sound. These vibrations and reflected sound waves cause distortion of the original audio waveform.
In order to solve this problem, we have developed a unique speaker support structure for the "ECLIPSE TD." Each speaker unit is supported by 5 stays that are connected directly to the pedestal and extend outward toward the edge of the unit (512).
The "ECLIPSE TD" therefore employs a floating structure, in which the enclosure and speaker units are mechanically separated.
2. Grand Anchor: Providing Complete Absorption of Vibration from the Speaker Diaphragm
Although separating the speaker units from the actual enclosure can prevent the occurrence of unwanted vibration, this method of construction necessarily results in the loss of the scaffolding required to support the reciprocating motion of the speaker diaphragm. To overcome this problem in the "ECLIPSE TD," the speaker units are secured through the use of a massive iron weight called a "Grand Anchor," which weighs approximately 3.3 kg (512).
The construction of the "ECLIPSE TD" enables the achievement of an ideal piston motion, as vibrations from the speaker diaphragm are completely absorbed by the large mass of the Grand Anchor.
3. Eggshell Construction: Dispersing Stress to Prevent the Occurrence of "Boxy" Sound
Box-shaped enclosures, which are popularly utilized for speaker systems, have many problems. It is commonly known that such enclosures facilitate the formation of standing waves due to reflections from the parallel interior surfaces. These standing waves tend to emphasize certain frequencies, thus producing a "boxy" type of sound. This situation presents an enormous obstacle in the implementation of "time domain theory," which has as its core concept the exact reproduction of the impulse waveform. In order to solve this problem, the "ECLIPSE TD" utilizes a unique eggshell geometry in its enclosure design.
The eggshell-shaped enclosure eliminates both resonance due to internal sound wave reflection and the diffracted waves that would normally be generated from the corners of a box-shaped enclosure. [Figure 6]

Achieving the ideal - the innovative geometry and revolutionary internal structure of the "ECLIPSE TD" have been created through our continuous and uncompromising pursuit of truly original sound, based upon the use of "time domain theory."
