About T1 Super Tweeter
The T1 super tweeter resides in a Stilla-Sphere housing on the Telesto. This location provides optimum dispersion, minimal interaction, and a stable sound stage.
T1 is phase-tuned to work uniformly with the M2 compression driver. Getting a separate super tweeter to work homogeneously with the rest of the speaker has traditionally been difficult. The drivers’ synchronous development overcomes this. Their dispersion and energy constant are synchronized, making them transparent as one unit.
The T1 super tweeter is based on a silk dome diaphragm, which produces precise, soft, and fatigue-free reproduction. The silk dome is Accumax coated, which retains the excellent audio properties of pure silk while eliminating the mechanical break-up inherent in pure silk at higher frequencies.
T1 has a very powerful motor system based on a rare earth Neodymium magnet. This construction ensures a uniform and stable response and tonality regardless of frequency and volume.
A special elongated version of the Earthquakes Vortex cooling unit effectively removes heat from the tweeter motor system, thus safeguarding against compression.
About M2 Super Midrange
The unique M2 super midrange results from Earthquakes’ Hybrid Phase-Corrected Parabolically Loaded Compression Driver Technology using the PLD (Parabolical Loading Device). The advanced design solves several longstanding challenges in loudspeaker design. Its increased upper-frequency response ensures a perfect transition to the T1 super tweeter. The good sonic properties of a super tweeter are often challenging to integrate, as traditional mid-tones are not fast enough or their dispersal pattern is different, leading to noticeable non-uniformity.
The M2 super midrange overcomes these challenges with a controlled dispersion, perfectly matching the T1 super tweeter. Its unique design also keeps the cone diameter at 1.25 inches, making it fast and articulate. This speed, which thus increases upper bandwidth, categorizes M2 as a super midrange.
The M2’s high-tech design has many advantages. Its fundamental design elements eliminate problems that have traditionally been solved through refinement. Here, they are genetically removed from the design, resulting in a detailed and utterly compression-free sound—so unhindered and shackle-free that sound exits the speaker almost as if it were lightning.
It is uncanny to find yourself blinking at the onset of transients. Your body’s natural defense mechanism takes over, detecting that this is “real” and that something is coming your way—impact imminent.
Parabolic loading has many advantages over typical horns but without the horn artifacts and inherent sound characteristics. It increases the driver’s coupling to the air, which increases sensitivity. Optimization and strict control of air impedance in the parabolic dish ensure maximum coupling without tonal shift or hardness.
The aerodynamic phase corrector in the middle of the parabolic dish ensures proper phase and accurate dispersion control. The dome, made of Accumax-coated silk, produces precise, organic reproduction.
Compression drivers often have metal cones, which can produce a hard sound because the sound is reproduced by metal and then acoustically amplified by metal or a hard surface through a horn. The M2 compression driver design, coupled with the silk dome, has a significantly milder compression factor / acoustic multiplier, resulting in dynamic and artifact-free sound.
About M4 Midbass Drivers
The M4 bass-midrange is a 4-inch long-throw driver with a ballistic grade Kevlar Cone. A high-speed and light midbass/midrange is needed to ensure a perfect and seamless transition from the M2 super midrange and a solid hand-off to the XLT-8 subwoofer driver.
The Dupont Corporation invented Kevlar in the early 60s, and it has been used in loudspeakers for many years because it is light, rigid, and anechoic. These advantages come with their own set of challenges, Kevlar is expensive and difficult to integrate which is why you often see a low-grade Kevlar (low-thread-count) used in loudspeakers. By using a low-grade Kevlar, most of its unique properties are lost. The M4 bass midtones use the highest ballistic grade Kevlar. The cones are lightweight and highly rigid, guaranteeing pistonic behavior far beyond their crossover point. Kevlar is an aramid fiber that is very sensitive to moisture and absorbs moisture if it is not specially processed. The Kevlar cone constructed by Earthquake undergoes a unique epoxy evaporation process, making it invariant to humidity.
The M4 units are of the long-throw type. It is somewhat unusual for a bass-midrange to be designed using this geometry, especially when crossed at 350Hz. This means the unit rarely experiences low frequencies that could exploit the long stroke.
The great throw potential is obtained using high Santoprene edge suspension, the special Earthquake Super Spider centering unit, and a voice coil with a winding height of nearly 2 cm.
Several unique benefits arise from using the long-throw design in the M4. Since only a tiny portion of the large throw potential is needed, the unit can be designed to change the suspension compliance within the unit’s actual travel. It overcomes any CMS compression found in typical drive units. The Unit’s suspension is so compliant that it easily moves if you blow on it.
The high voice coil winding height combined with an oversized strontium-cobalt magnet system provides a strong electromotive interaction, keeping the unit in an iron grip. The suspension will never hamper travel since the device can move more than required. This means that the electrical impulse always controls the cone, ensuring that the distortion caused by mechanical self-braking will never arise. This gives the engaging and infectious dynamic sound you can experience during live music.
About XLT-8 Woofer
Telesto is equipped with Earthquake’s XLT-8 (Xtra Long Throw) woofer mounted on the side of the Telesto tower. The XLT-8 woofer is a variant of the woofer that has excelled Earthquake’s MiniMe P8 subwoofer as the market’s most powerful subwoofer in its size class.
With a thunderous response down to 30Hz, many find a subwoofer utterly superfluous. The XLT-8 woofer is constructed using Earthquake’s XLT geometry, an evolution of the generic long-throw architecture. The cone is a composite of cellulose and fiberglass that is lightweight and rigid. High Santoprene surrounds and super spiders result in excellent mobility.
An oversized copper voice coil coupled with a strong strontium-cobalt magnet system produces an articulate and detailed bass response. The robust electromagnetic interaction between the voice coil and magnet produces a very high reactive impedance. This guarantees that the energy is converted into motion and not heat. This avoids heat-derived compression. The Telesto bass response stays accurate and taunt regardless of complexity and listening level.
About Hemi Elliptical Cabinet
The Titan Tigris tower speaker cabinet is designed using traditional Scandinavian boat-building principles and features a Hemi Elliptical shape, which minimizes reflections and standing waves for clear and dynamic sound.
Unlike typical cabinets that use router grooves for bending, the Titan Tigris employs Earthquake’s proprietary N-Flex method. This technique uniformily layers steam-bent wood without compromising structural thickness, resulting in a robust cabinet made of eight layers of high-density fiberboard (HDF), 30 mm thick.
Each cabinet also includes an internal skeleton made from a unique wood and epoxy composite, enhancing strength and resonance control.
The finishing process involves priming, sanding, and applying multiple layers of black lacquer, followed by a polished clear coat, achieving a refined and elegant appearance.
