THIEAUDIO Monarch MKIV
Custom Tuning at Your Fingertips
Flagship-level detail meets bone-rattling bass—custom-tuned at your fingertips.
Switch between studio-neutral and basshead tunings whenever you want. For the first time in Thieaudio’s Signature Series lineup, the Monarch MKIV (Mark Four) comes with an adjustable tuning switch. Extensive R&D has led up to a functional tuning switch that is stylish, easy to use without tools, and makes an extensive impact on the tuning. Users can switch between “STANDARD” and “RUMBLE” modes.
Switch between Standard & Rumble Mode
RUMBLE adds an additional 3dB to the entire sub-bass shelf, increasing both the sub-bass and low-mid power. With RUMBLE, the overall tuning profile becomes thicker, warmer, and more powerful. Monarch MKIV’s tuning switch allows users to enjoy both Monarch’s signature neutral tuning, while giving the option to experience the powerful bass slam like that of the Thieaudio Origin.
T6 Aircraft Grade Aluminum Construction
The Monarch MKIV elevates its status by utilizing a premium T6 aluminum alloy shell. Precision CNC engineering achieves our most durable, yet lightweight, shell. Surface hardening also ensures more scratch resistance and corrosion resistance against sweat. Experience the fullness of your music with featherlight comfort in your ears.
An All New Tuning Profile
The Monarch MKIV encompasses both tradition and modernity in its tuning profiles.
In STANDARD tuning mode, the MKIV goes back to its roots by bringing back a studio-neutral tonal balance. The sub-bass dishes out a whopping 10dB of hard hitting bass, but with a sharp 150Hz low-mid cutoff, the bass is fast and precise, allowing for a clean midrange. The midrange has been cleaned up to be more neutral between 150Hz and 1kHz, while the treble is more crisp and natural.
Compared to the previous generation, the MKIV’s treble focuses more on vocal clarity while eliminating unnecessary upper treble harmonics for a smoother and more candid treble extension.
Rumble Mode
In RUMBLE mode, the low-mid crossover is loosened, unleashing a more powerful bass and thicker mids. The sub-bass is boosted to 13dB to enable significantly greater thump and low-end presence. The low-mid range at 200Hz to 500Hz is also boosted by 2dB, giving greater body, depth, and texture to bass guitar, male vocals, and fundamental notes of instruments. RUMBLE is designed for those who love a thicker body in their music and want a more engaging bass.
The Monarch MKIV is meticulously tuned with 9 independent passive crossover components with a passive 4-way crossover network, 4 independent sound tubes, and impedance grounding network.
IMPACT2
The IMPACT2 (“Impact Squared”) is THIEAUDIO’s tried and true subwoofer solution consisting of two latest generation of 8mm composite diaphragm drivers arranged in an isobaric design. The new 8mm dynamic driver focuses on speed and hard-hitting slam for a powerful, yet clean sub-bass thump. The usage of two 8mm subwoofers significantly enhances the power and texture of the bass, while our in-house isobaric chamber design keeps the frequency and pressure constant. This means you can enjoy better quality bass without sacrificing tonal integrity.
Electrostatic Tweeters
The Monarch MKIV completely redesigns EST driver utilization. By more efficiently targeting the treble range of its balanced armature tweeters, the Monarch MKIV can focus the EST tweeters specifically at the 10-40kHz region. This new crossover technique allows smoother treble transition between the BA and EST drivers for a more natural treble timbre, while simultaneously enhancing EST output into the ultra-treble range. The result is a greater treble extension compared to previous generations while sounding smoother and more natural. Enjoy the spacious soundstage, clarity, and air in the sound - more comfortably.
Next Generation of Modular Cable System
The Monarch MKIV comes with the latest iteration of Thieaudio’s modular cable system: Chocolate. Consisting of thick 8 strands of ultra pure oxygen-free copper (OFC) wires and silver plated OFC wires, enjoy cleaner and more fuller audio transmission. The modular plug design allows users to switch between 4.4mm balanced and 3.5mm unbalanced plugs for integration with any audio device.
