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. 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.\n\n\n\n\nT6 Aircraft Grade Aluminum Construction\nThe 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.\n\n\n\n\n\nAn All New Tuning Profile\nThe Monarch MKIV encompasses both tradition and modernity in its tuning profiles.\nIn STANDARD tuning mode, the MKIV goes back to its roots by bringing back a studio-neutral tonal balance.

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.\n\n\n\n\n\nIn RUMBLE mode, the low-mid crossover is loosened, unleashing a more powerful bass and thicker mids.
