Ultimate high fidelity, the perfect evolution

In 2004, Eclipse released TD712z, the flagship of the ECLIPSE TD range. This became the ultimate standard for the Eclipse brand.

Analogue speaker design has changed little since it began and achieving landmark progress presents a considerable challenge. To develop the original TD712z, Eclipse studied and tried new technologies with countless listening tests.

'There is no limit in the pursuit of the ultimate: tuning each individual detail brings evolutionary progress.'

Eclipse’s target for TD712zMK2 was to extend the frontiers of performance achieved with the original. Because they wanted to offer a wider frequency response, and improved power handling, they undertook a fundamental review of all elements and functions. As a result, Eclipse achieved an even better impulse response than the original TD712z, which they thought would not be feasible at the launch in 2004.

So now, the artistry of music, the thoughts and feelings of artists themselves, the distinctive sounds of each instrument, the exquisite harmonies woven from numerous musical notes – you can experience it all with the new TD712zMK2 like you've never experienced it before.

Custom Full Range Driver. The material for the drive unit has been selected to provide the optimum performance from the cone. It needs to be extremely light with great elasticity, combined with high radial rigidity. It is supported by a highly flexible surround and damping system in a magnetic circuit to provide precise piston movement.

Diffusion Stay. Colouration of sound reproduction will occur if the speaker cone is allowed to cause the speaker enclosure to vibrate. ECLIPSE TD speakers minimise this issue with a sophisticated 'diffusion stay' whereby the drive-unit is held in a floating mechanism so that no residual vibration can be transferred from the unit itself to the enclosure.

Magnetic Circuit. To make the most of the custom driver, it must be driven correctly by the magnet, which effectively the engine of the speaker. The ECLIPSE TD speakers incorporate a specially designed circuit to ensure a high magnetic flux density, creating a powerful magnet with an optimised voice-coil.

Eliminating Vibrations & Acoustic Solutions. In order for its floating enclosure to be effective we have achieved an air-tight seal, whereby the drive-unit is sealed to the enclosure, eliminating the transmission of unwanted vibrations. This requires a permanent bond combined with a flexible coupling.

Mass Anchor. A high mass, conical anchor weight has been placed on the back of the drive-unit magnet. This structure acts as a mass sink, which 'grounds' the drive-unit ensuring the ideal piston movement.

Egg-Shaped Form. The internal standing and diffraction waves generated at the front baffle edges are largely eliminated by adopting a rigid yet tactile egg-shaped form, in which no two radial surfaces are in the same plane. 

Egg-Shaped Form

In ECLIPSE TD series, the internal standing and diffraction waves generated at the front baffle edges are largely eliminated by adopting a rigid, yet tactile egg-shaped form, in which no two radial surfaces are in the same plane. With TD712zMK2, the wider frequency response has been dramatically improved by increasing the internal volume of the cabinet by approximately 50% from the original model, which also helps to reduce the back pressure on the driver for better impulse response.

12cm Full Range Driver

Because the cone needs to be

extremely light, offering greater elasticity whilst still possessing high radial rigidity, fibreglass has been chosen as the ideal material for the drive-unit. It is then connected to the enclosure by a highly flexible, rubber surround incorporating a re-designed damping system. This allows precise, lateral piston movement. The magnetic flux density is approximately 10% greater than in the TD712z, providing more powerful motor system.

Solid Foundation

TD712zMK2 and its stand is an 'all-point' contact design, achieved by using three steel legs mounted in the top of the column in combination with a specially machined, locking ring. This design eliminates undesirable vibrations, ensures tighter lower frequency performance and allows for angle adjustments, which is an unusual option for high-end speakers. Adjustments of 0 to 12 degrees of the head angle offer a wide range of flexibility in installation to suit the individual listening environments.

Well Damped Stand

The dramatic, streamlines form of the stand echoes the design of aircraft wings in restraining the reflection of spherical waves. It is made from a combination of extruded and die-cast aluminium, offering both high rigidity and extensive internal damping, which eliminates any residual vibrations. The stand is filled with high-density, irregular sized kiln dried sand. It is the combination of these elements in the structure that allows precise reproduction of low frequency waveforms. Functional beauty was born from seeking high-performance.


TD712zMK2 base adopts an unusual integrated spike and insulator foot arrangement, which delivers unique waveform reproduction capabilities. The mounting to the stand is by all-point-contact so that any minuscule residual vibrations from the drive-unit movements are further isolated from the floor. The speaker can be moved without scratching the floor and adjustments can easily be made manually and without the use of special tools.
