When Legendary Drivers Meet

When most IEM manufacturers develop dual driver IEM’s, they are purposefully fated to be the entry-level, low-tier, and affordable compromise to their more expensive counterparts. For this reason, cheaper, less efficient drivers are selected, put together with less thought on acoustic design, ultimately resulting in an under-performing monitor. Thus, when our team came together to craft the Legacy 2, we dedicated ourselves to achieve the highest performance possible, carefully selecting components, and merging them through months of sonic engineering. 

Bass performance has always been of particular importance to the Thieaudio team, which is the reason why the Legacy series, with its incorporation of dynamic driver woofers, was started. Our team has come a considerable way in developing dynamic drivers, and we are proud to utilize our latest advancements into the Legacy 2. Featuring our new proprietary closed-back 10mm Beryllium dynamic driver, the Legacy 2 takes the biggest leap yet in bass performance. Beryllium drivers have developed a cult-like following in the audiophile community due to the stiffness of this element, which results in extremely quick responses. By using stronger internal magnets and a new acoustic casing design, we have taken this driver to its full potential, producing low-frequency responses beyond anything the Legacy series has achieved so far. 

In selecting the mid-high frequency driver, we have decided to utilize the tried and true legendary balanced armature, the Knowles ED29689. Famed particularly for its performance in popular single-BA driver monitors, the Knowles ED29689 has been widely acclaimed as the foundation of all balanced armature drivers, and still stands today as the most capable and best performing driver. Particular to our interests, the ED29689 features a completely neutral mid-frequency response, accurate mid-treble transition, and a highly resolving treble playback. 

By using similar tuning strategies as those found in our Signature series models, the Legacy 2 has been engineered to produce a powerful sub-bass impact that transitions crisply to the mid-frequencies, which in turn are presented naturally, with minimal coloring. The treble has been tuned to perfectly balance the ED29689’s high calibre treble resolution and the human ears’ preference for high-frequency decay. Through careful selection of the drivers and intricate tuning strategies, we have created the ultimate 2 driver in-ear monitor, that beyond its mere name, is truly a performance-grade monitor for both stage and audiophile use. In no way is the Legacy 2 a compromise, and we are confident that it stands to compete against any competition in the field, regardless of the driver count.
