Four woofers and symmetrical coverage for large screens and higher output
MK Sound M90 is the largest M Series model, with four 4-inch woofers, a 1-inch tweeter and symmetrical geometry suitable for centre-channel use.
MK Sound M90 belongs to the M Series and is designed for front or centre channels in systems with large displays and higher output requirements. The two central woofers operate as midrange drivers while the outer pair extends bass output, using separate acoustic chambers to reduce resonances. With 89 dB sensitivity, 4-ohm nominal impedance and recommended amplifier power of 25-200 W, M90 follows the M Series philosophy with greater radiating area and dynamic capability.

- Response extending to about 70 Hz.
- Symmetrical vertical and horizontal coverage.
- Suitable for front or centre-channel use.
- Long profile for large displays.
- Black Satin or White Satin finishes.
Acoustic design
Four 4-inch glass-fibre woofers are divided into anti-resonant chambers and work with a 1-inch coated-silk dome tweeter. Rated response extends to about 70 Hz. The crossover works at two points, 600 Hz and 2.0 kHz, distributing the work between four woofers and tweeter while preserving the symmetry useful in LCR applications.
Role in the system
Vertical and horizontal symmetry allows M90 to serve as a centre speaker while maintaining uniform coverage and matching the front channels. Its greater acoustic output suits larger screens and more dynamic listening than M50 or M70. Wall brackets, screws and supplied accessories match the model's on-wall purpose, allowing a broad front stage without relying on deep furniture or stands.
Crossover and timbre matching
The Phase-Focused network aligns the woofer groups and tweeter to preserve consistent response when the speaker is used in different LCR positions.
Installation and dimensions
The cabinet measures about 80 x 13 x 8.5 cm and weighs about 5.6 kg. The elongated, shallow profile is designed to complement large TVs and screens without taking much room space.
Construction and finishes
Separate chambers reduce resonances associated with slim cabinets and improve control of the four woofers. Available in Black Satin or White Satin.
