Alta Audio has announced the imminent arrival of the new Reference Titanium Hestia II, a significant step up from the original model. The Titanium Hestia II (SRP: $37,500 in piano black; additional finishes available at moderately higher prices), is, like its namesake, a three-way tower speaker with drivers arranged in an open-back D’Appolito configuration, in which midrange drivers are placed above and below the tweeter — creating a unified wideband pulse response that most closely mimics the original sound pulse.
Alta Audio’s founder, CEO, and product designer, Michael Levy, improves upon the original Hestia by updating the crossover with a design like that of the Adam floorstanding speaker, which was introduced earlier this year. The updated design features new 7-inch midrange drivers, updates to the amorphous core transformer in the tweeter, new silver-coated deoxygenated copper multi-strand variable diameter Teflon insulated internal cabling, and updated crossover components, including silver foil capacitors.
The output of the two lower midranges matches the output of the single 6-inch midrange above the tweeter, thus creating a unified pulse. In the woofer crossover passband, the two 7-inch lower midrange drivers produce the extended lower midrange and bass response needed to seamlessly blend with the XTL Bass (patent pending) woofer.
Alta Audio surrounds the voice coils in a newly developed titanium former that offers lower mass, greater stiffness, and smoother response than traditional aluminum designs, resulting in a lack of magnetic flux with clean, open dynamics.
By adding these new elements in a newly retuned crossover based on the concepts incorporated in the company’s recently introduced Adam speakers, Levy smoothed out the impedance, making the speaker less sensitive to amplifiers while increasing the phase linearity of the design. In addition, the bass response has better control and is deeper and more dynamic than the original Titanium Hestia as with updated tuning thanks to the latest version of Alta Audio’s lossless XTL transmission line technology.
Available in Alta Audio’s super high-gloss black onyx finish with other colors available on special order, the Titanium Hestia II features the best of Alta Audio’s proprietary audio technologies. Alta Audio’s amorphous core transformer, used in the high output 70 MM ribbon tweeter, is responsible for the natural and detailed high-frequency response. Likewise, the 6-inch cone titanium former upper midrange and two titanium former 7-inch lower midranges provide low distortion and fast transient response.
Rounding out the driver complement is a 10-inch woofer whose tuning parameters are coupled to the unique cabinet design for its infrasonic (floor-moving) bass and for refined cohesion between the Adam’s XTL (Extended Line Transmission) and its pure aluminum ribbon tweeter. Extended Transmission Line is Alta Audio’s proprietary technology that applies sonic geometry to tune speaker cabinets as if they are musical instruments, delivering an accurate, fast, and powerful low frequency response.
The distinctive angles of the Titanium Hestia II, which stands 53.75 inches H x 15 inches W at the bottom x 8 ½ inches W at the top x 18 inches D at the bottom, contribute to its ability to reproduce the detail, dimensionality, and feel of a live performance. Its three-way design creates a natural – and neutral – listening experience.
Alta Audio’s Titanium Hestia II features a frequency response of 28 Hz to 47 kHz, sensitivity rated at 90 dB/2.83 Volts @ 1 Meter, and an impedance of 4 ohms. Recommended power handling is 50–400 watts per channel, bi-wired or bi-amped.
