TWR1 Wideband Tweeter


The dual TWR1’s are phase tuned to work uniformly with each other. It has traditionally been difficult to get separate tweeters to work seamlessly together, this is overcome by synchronous development of the drivers. Their dispersion and energy constant is synchronized so they appear transparent as one unit.

The TWR1 tweeter is based on a silk dome diaphragm resulting in 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.
TWR1 has a very powerful motor system based on a rare earth neodynium magnet. This construction ensures a uniform and stable response and tonality regardless of frequency and volume.


MR4-XLT Ballistic Kevlar wideband woofers


XLT_Logo_final_large.jpgThe MR4-XLT bass-midrange is a 4-inch XLT (Extra-long-throw) driver with a ballistic grade Kevlar Cone. This ensures a perfect and seamless transition from the TWR1 wideband tweeters.

Kevlar was invented by the Dupont Corporation in the early 60s and 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 special properties are lost. Titan Theia uses the highest ballistic grade Kevlar. The cones are lightweight and extremely rigid guaranteeing pistonic behavior far beyond their crossover point. Kevlar is an aramid fiber and is very sensitive to moisture and absorbs moisture if not specially processed. The Kevlar cone constructed by Earthquake undergoes a special epoxy evaporation process making the Kevlar invariant to moisture.

The great throw potential of the MR4-XLT is obtained by using high Santoprene edge suspension, the special Earthquake Super Spider centering unit, and a voice coil with a winding height of nearly 1.5 cm.

Several unique benefits arise by the use of the XLT (extra long-throw) design. Since only a portion the large throw potential is typically used, the unit can be designed so that the suspension compliance is unchanged within the unit's nominal travel. It overcomes CMS compression found in traditional 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 which keeps the unit in an iron grip. Since the device can move more than required, the travel will never be hampered by the suspension. This means that it is always the electrical impulse that controls the cone. It ensures 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.
