Tangzu Harmonic Empire Xiao Qiao / XiaoQiao Rock Green Edition

Design Concept

Rooted in the critical point between restraint and explosion in rock music: the green cavity is calm yet full of vitality. The black metal cover is combined with a fluorescent green embossed cover, presenting a restrained yet striking green-black contrast in daylight. In dim light, fluorescent textures emerge like stage lighting sweeping across. 

7N single crystal copper Upgrade speaker wire

The cable uses Furukawa high-purity oxygen-free copper silver-plated material, balancing thick bass and transparent highs. All hardware adopts a custom all-black design. The plug and splitter are printed with the exclusive Xiaoqiao logo — details echo the black metal panel and fluorescent engraved cover of the Rock Edition, creating a unified visual language from cavity to cable.

Acoustic Architecture

The cavity features a composite structure of 5-axis precision-carved aviation-grade aluminum alloy and high-transparency resin. Aviation aluminum is precisely CNC-machined to form a rigid metal frame and acoustic conduit, ensuring resonance control and durability.

0.78mm Dual-Pin Swappable Cable Design

Adopts the mainstream 0.78mm dual-pin swappable connector, compatible with most upgrade cables and Bluetooth modules on the market, leaving ample room for future upgrades. Whether you want to replace the cable to enhance bass texture or connect a Bluetooth module for cable-free freedom, these two small pins accompany your rock journey from entry to advanced level.
