Design concept

Technical Audio Devices Laboratories, Inc. (TAD) introduces the Titanium Silver Micro Evolution One, expanding the color options of the world renowned Micro Evolution One, introduced autumn 2016.  The TAD-ME1-S has been crafted by TAD in a sophisticated, warm and elegant titanium silver paint polished to a high gloss mirror finish and complimented by sandstone steel side panels.  

Featuring an identical 16-cm woofer, 9cm CST1 driver and Bi-Directional ADS2 port as the original Micro Evolution One, the TAD-ME1-S produces the same accurate image localization with excellent sound field expression and resolving, natural and rich bass reproduction.

TAD will expand the product lineup of its Evolution series to respond further to customers’ needs.

Main Features

1) Refined and Elegant Titanium Silver Finish

The Titanium Silver finish is created by skilled TAD artisans performing a painstaking 17 step process of paint coating, sanding and careful polishing to produce the unique and tasteful high gloss mirror finish. Artistic visual balance is obtained by TAD with a fine sandstone texture and color applied to the steel plates that constitute the side panels of the Bi-Directional ADS port. By combining different colors, textures and materials, the TAD-ME1-S exhibits a refined and tasteful appearance appropriate for the most discerning interior design.

2) 9-cm CST Driver for a Stable Localization and Natural Sound Field

TAD’s CST Driver was designed to align the midrange and tweeter sound source positions to make the midrange diaphragm work as part of the tweeter waveguide. This design homologizes the phase and directional characteristics of midrange and tweeter sounds at the crossover, achieving natural attenuation characteristics and ideal directional patterns over the entire frequency range.

For the tweeter diaphragm, TAD has consistently used beryllium for its highly rigid and extremely lightweight properties, as well as high internal loss. Its shape was configured with HSDOM 3 , an optimization technique undertaken by computer analysis, to achieve an optimum balance between a divided vibration and a piston motion. All these properties deliver ultrahigh frequency characteristics up to 60 kHz.

A magnesium midrange diaphragm is used for its high internal loss and the lightest properties among practical metals to eliminate coloration inherent in the material and reproduce pure midrange sounds with low distortion.

The CST excels in both phase and directional characteristics over a wide band from 420 Hz to 60 kHz, providing a stable localization and natural sound field.

3) 16-cm MACC4 Diaphragm Woofer for Improved Linearity and Optimized Driving Force

For ideal characteristics, TAD developed a new woofer diaphragm laminated with woven and non-woven fabrics of aramid fibers. A voice coil uses a highly rigid titanium bobbin, resulting in the accurate response of the diaphragm. This provides substantial heat dissipation to ensure power linearity, contributing to the reproduction of clear bass sound and faithful low-midrange sound with no coloration.

The woofer also uses LDMC5 and a foaming polycarbonate-based urethane edge that increase the linearity of the drive and support systems. Coupled with an optimized bass-reflex enclosure, the driving force strengthened by a large ferrite magnet reproduces clear, deep bass sounds without distortion.

4) Bi-Directional ADS Port for Natural, Deep Bass Sounds

Originally utilized in the design of the TAD-CE1 speakers, the Bi-Directional ADS Port features slit-shaped ports located on both sides of the enclosure. These ports lead to the forward-and-backward openings and are horn-shaped to drive the port smoothly and efficiently. This design reduces port noise at high amplitude and prevents the leakage of low-order internal standing waves from the port, eliminating adverse influence on the woofer bandwidth and producing a clear, quick response mid-low frequency range sound characteristic. The bi-directional (forward-backward and left-right) layout of the port openings cancel vibration force within the enclosure, reproducing deep and powerful bass sounds.

5) SILENT6 Enclosure to Reduce Unwanted Cabinet Resonance

For high strength and low resonance, TAD uses the SILENT enclosure that combines a highly rigid birch plywood frame with an MDF (medium density fiberboard) outer panel with high internal loss. A 4 mm thick steel panel covers the left and right sides of the cabinet to further prevent unwanted resonance. TAD also analyzed internal standing waves in the enclosure to select and effectively place optimal acoustic absorbing materials, contributing to the elimination of internal standing waves, which would adversely influence the sound imaging and sound field.

6) Isolated Network Filter to Minimize Interference

The design isolates the network filter assembly for CST (tweeter/midrange) and the woofer to minimize interference. The CST filter uses a PP film capacitor, a noninductive resistor, an air-core coil, and other carefully selected parts, while the 16-cm woofer filter uses a low-loss core coil with excellent magnetic properties, as well as a low-loss electrolytic capacitor, a non-inductive wire-wound resistor, an air-core coil, and other carefully selected parts, to reduce resistance caused by series insertion as much as possible. All these devices result in the reproduction of undistorted, clear sound and a fluent sound field.

Each components value was determined to optimize the acoustic output, energy, impedance, and other characteristics, providing slope characteristics that optimize the response and phase characteristics.
