NEW YORK CITY, NY / ACCESS Newswire / June 20, 2025 / THIEAUDIO, a global leader in high-fidelity audio innovation, proudly announces the release of the Monarch MKIV, the latest generation of its legendary Monarch series. Combining technical mastery with user-focused customization, the Monarch MKIV introduces a new era of flexibility, refinement, and acoustic power for audiophiles.
For the first time in Thieaudio's Signature Series lineup, the Monarch MKIV comes with an adjustable tuning switch. Extensive R&D has led to a functional tuning switch that is stylish, easy to use without tools, and has a significant impact on the tuning.
An All-New Tuning Profile
The Monarch MKIV encompasses both tradition and modernity in its tuning profiles.
STANDARD mode returns to a studio-neutral sound, with 10dB of impactful sub-bass and a sharp 150Hz cutoff for fast, clean bass and a neutral midrange. Treble is crisper and more natural than the previous generation, focusing on vocal clarity while smoothing out excessive upper harmonics.
RUMBLE mode loosens the low-mid crossover for fuller bass and thicker mids. Sub-bass is boosted to 13dB, while the 200-500Hz range gains 2dB, enhancing body and texture in bass guitar, male vocals, and instruments-ideal for those craving a richer, more powerful sound.
IMPACT² Dual Subwoofer System
At the heart of the MKIV lies IMPACT², THIEAUDIO's proprietary isobaric subwoofer module. Using dual 8mm dynamic drivers arranged in a pressure-controlled chamber, IMPACT² delivers fast, punchy, and textured bass that enhances musical depth without overwhelming the mids. This unique design offers a sub-bass response that is both impactful and clean, ideal for bass lovers who still crave tonal accuracy.
Refined Treble with Redesigned EST Drivers
To deliver airy highs with greater finesse, the Monarch MKIV incorporates redesigned Sonion electrostatic (EST) drivers, extending treble performance up to 40kHz. A completely re-engineered crossover allows for smoother transitions from balanced armatures to ESTs, removing unwanted harshness and improving treble timbre. The result is a spacious, natural soundstage with heightened vocal clarity and realistic instrument separation.
Premium Grade Aluminum Alloy Shell
The MKIV debuts a CNC-milled Grade 5 aluminum alloy shell, offering superior durability, corrosion resistance, and scratch protection. Despite its robust build, the housing is featherlight and ergonomic, ensuring fatigue-free wear for long listening sessions. It's a blend of form and function designed for audiophiles on the move.
Next-Generation Modular Cable
The Monarch MKIV also includes THIEAUDIO's latest modular cable system, crafted from high-purity silver-plated and oxygen-free copper wires. With interchangeable 3.5mm and 4.4mm plugs included.
