The THIEAUDIO HYPE 4 MKII is a complete redesign featuring new Knowles drivers and the Gen 2 IMPACT2 subwoofer system, delivering powerful bass, rich mids, and crystal-clear highs. Handcrafted with precision tuning and a premium modular cable, it offers studio-grade sound and exceptional build quality.
Completely Redesigned for Performance
The HYPE 4 MKII is not just a retuning - it’s a complete redesign from the ground up. Featuring brand new balanced armature drivers from Knowles, second generation IMPACT2 sub-woofer system, and a new engineering approach, the HYPE 4 MKII makes leaps in both tonal and technical performance.
Gen 2 IMPACT2
The HYPE 4 MKII incorporated the latest generation of the IMPACT2 sub-woofer system, which is shared with the Monarch MKIV. Two 8mm composite diaphragm dynamic drivers encased in THIEAUDIO’s proprietary pneumatic acoustic chamber pumps out tight, focused, and deep sub-bass thumps - all while keeping the rest of the frequency range clean and neutral.
Knowles Balanced Armature Drivers
The MKII design was developed from the ground up. Using imported American Knowles balanced armature drivers, the HYPE 4 MKII makes no compromises when it comes to tonal and technical excellence. Two of the latest Knowles RAB series drivers focus on rich and pronounced low-mids, while separate ED-33465 driver layers up on mid-treble frequencies. This crossover strategy significantly enhances imaging capabilities as well as tonal depth in the midrange. A single Knowless RAD-33518 ultra-tweeter has been strategically positioned within the nozzle for an upper treble extension that rivals electroststic and planar drivers.
Premium Modular Cable
The HYPE 4 MKII features our new performance cable, with 7N ultra-OFC copper and silver-litzed wires. With a thick 4-core design, the cables feel as premium as they sound transparent. With a modular plug system, you can swap out between 4.4mm balanced and 3.5mm unbalanced plugs for compatibility with any device.
