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 Next-Level Performance: The HYPE 4 MKII is a full ground-up redesign, combining advanced engineering and precision tuning to deliver superior tonal accuracy, clarity, and immersive soundstage compared to its predecessor.
Gen 2 IMPACT2 Dual Dynamic Subwoofer System: Equipped with two 8mm composite diaphragm dynamic drivers in THIEAUDIO’s proprietary acoustic chamber, it produces deep, controlled sub-bass while maintaining clean mids and crisp highs for a balanced listening experience.
Upgraded Knowles Balanced Armature Driver Array: The HYPE 4 MKII features imported Knowles balanced armature drivers for uncompromising tonal and technical performance. Dual RAB drivers deliver rich low-mids, an ED-33465 driver adds mid-treble clarity, and a RAD-33518 ultra-tweeter extends airy, detailed highs rivaling electrostatic designs.
Precision Tuning and Handcrafted Engineering Excellence: With a 4-way crossover, 4-tube system, and CNC-machined aluminum housing, each unit is hand-assembled and individually quality-checked, ensuring durability, premium finish, and studio-level sound performance.
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.

Enhanced Tuning Approach
The key to THIEAUDIO’s global success has been its attention to tonal balance. We took a step back to assess what characterizes the intersection between studio neutral and musical enjoyment, and have incorporated our new tuning approach into the HYPE 4 MKII. The sub-woofer output is thunderous, with a 9dB output, but with a sharp cutoff at 150Hz, the bass is precise and free from bloating. The midrange features a lush 400Hz hump, while being neutral between the bass and treble cutoffs. This allows the midrange to be naturally warm, without being muddy, while remaining true to a studio monitor presentation. The treble is painstakingly tuned to feature a delayed decay, which allows excellent detail retrieval and upper headroom in the soundstage, while being free of harshness.

Excellence in Engineering
The HYPE 4 MKII is acoustically engineered with a 4-way crossover and 4-tube system featuring 7 separate passive components. Physically, the MKII is constructed from CNC-processed solid aluminum blocks, which are then finished by hand prior to being anodized for a professional look and durability. Each HYPE 4 MKII unit is hand assembled and undergo independent rounds of quality inspections at each manufacturing phase, including individual driver pairing, driver assembly, shell processing, final assembly, and packaging.

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.
