Signature Series

The Signature Series lineup of THIEAUDIO represents the pinnacle of our R&D skill sets, combining both the latest technology and innovative engineering to bring together top of the line IEM’s. The first two Signature Series models, the Monarch and Clairvoyance, were hailed globally as among the best IEM’s on the market. Following this success, we are proud to release two new twins tribrids: the Excalibur and Oracle.

The Excalibur and Oracle utilize the latest driver technology from the Danish manufacturer, Sonion - the Electrostatic (EST) tweeter. The EST driver features an ultralight membrane in a small tweeter chamber that is powered by an independent transformer to extend the in-ear monitor’s treble range up to 80kHz. In reality, the utilization of these drivers effectively enhances the extreme-treble response and thereby provides a protracted treble decay, a more airy atmosphere, and enhanced sound resolution. The correct implementation of EST drivers can make normal balanced armature driver earphones seem dull and lackluster in comparison.

THIEAUDIO Excalibur: The Legend Continues

The Excalibur is a 2EST+2BA+1DD tribrid design IEM, featuring three different classes of drivers matched based on their unique functional properties. In short, the tuning of the Excalibur can be described as “exciting”. Featuring powerful bass and crisp high’s, the Excalibur puts out an incredible sound that makes any genre sound its fullest and best. We recommend the Excalibur to those looking for a fun and enjoyable hifi listening experience.

The subbass and bass of the Excalibur is powered by a new 10mm polycarbonate dynamic driver to produce a deeper and more impactful low-frequency sound distribution. The driver has been further optimized with stronger magnets to increase its speed and response. We have chosen a customized American Knowles DFK series balanced armature (BA) drivers to reduce the total harmonic distortion (THD) in this fundamental region of the frequency spectrum, and because of its excellent pinna gain placement. Combined with our tuning capabilities, we are blown away by the performance of our new BA driver selection, and believe they will be an instant crowd pleaser. More importantly, these BA drivers match perfectly with the tonal characteristics of the Sonion EST drivers, creating a natural synergy that brings out impeccable detail retrieval, spacious soundstage, and an airy atmosphere.

Despite the sonic advantages of EST drivers, their relatively low sound output volumes mean that the tuning requires special engineering to balance out all of the drivers to make the EST drivers heard. Our prior experiences working with these drivers have honed our abilities to precisely calibrate all of the drivers in the system to best bring out the EST drivers. We believe that the Excalibur is among the very few IEM’s in the market that fully takes advantage of the full potential of EST drivers, and you’ll benefit from the crisp treble extension that is incomparable with any other drivers out there.
