M&K Sound

M&K Sound S300 THX Ultra2 Bookshelf/Stand Mounted Speaker (Each)

THX Ultra2-Certified Reference Monitor • Dual 6.5" Coated Glass-Fiber Woofers • Triple 1.1" Soft-Dome Tweeter Array • Constrained-Layer Double Cabinet • Made in Denmark

THX Ultra2 Reference Performance for Music and Home Cinema

The M&K Sound S300 THX Ultra2 Bookshelf/Stand Mounted Speaker (Each) is a reference-grade monitor engineered to reproduce music, dialogue and cinematic effects with exceptional neutrality, dynamic range and precision. Its dual 6.5-inch coated glass-fiber woofers and vertically aligned triple-tweeter array deliver high output, focused imaging and controlled dispersion for professional monitoring and uncompromising home theater systems.

Handcrafted in Denmark, the S300 uses an advanced box-inside-a-box enclosure with constrained-layer damping to suppress cabinet vibration and lower the mechanical noise floor. Its sealed design, carefully isolated driver assemblies and high-power handling make it equally suitable for left, center or right front-channel use, whether placed on a dedicated speaker stand or securely installed within a purpose-designed theater system.

Highlights & Benefits

  • THX Ultra2-Certified Performance — Engineered to meet demanding standards for output capability, frequency response, dispersion and low distortion in high-performance home theaters.
  • Exceptional Dynamic Range — A 93dB sensitivity rating and recommended amplifier range of 25 to 500 watts support effortless playback at both subtle and reference listening levels.
  • Precise Controlled Dispersion — The vertically arranged triple-tweeter array improves imaging while reducing unwanted reflections from floors and ceilings.
  • Flexible LCR Placement — May be used as a left, center or right front-channel speaker for a perfectly matched soundstage across the front of the room.
  • Handcrafted Danish Construction — Premium cabinet materials, proprietary drivers and carefully engineered internal damping provide long-term durability and consistent performance.

Technology & Design

Dual 6.5-Inch Coated Glass-Fiber Woofers — The rigid, lightweight cones deliver controlled midbass, accurate vocal reproduction and exceptional transient response with reduced coloration.

Triple 1.1-Inch Soft-Dome Tweeter Array — Three vertically aligned high-frequency drivers produce detailed treble, high output and precise horizontal coverage while controlling vertical dispersion.

Constrained-Layer Double Cabinet — The box-inside-a-box enclosure joins two cabinet structures with a non-resonant damping layer to reduce panel vibration and lower the speaker’s mechanical noise floor.

Mechanically Isolated Driver Assemblies — Custom die-cast woofer and tweeter mounting brackets create a rigid connection to the front baffle while isolating the drivers from unwanted cabinet resonance.

FAQ — M&K Sound S300

Is the M&K Sound S300 sold individually?

Yes. This listing includes one M&K Sound S300 speaker. Two speakers are required for a conventional stereo pair, while three may be used for a matching left, center and right front soundstage.

Can the S300 be used as a center-channel speaker?

Yes. The S300 is designed for left, center or right front-channel use. It should remain vertically oriented to preserve its intended dispersion and imaging characteristics.

Does the S300 require a subwoofer?

A subwoofer is strongly recommended for full-range music and home theater playback. The S300’s sealed response is designed for accurate integration with a capable M&K Sound powered subwoofer.

What amplifier power is recommended for the S300?

M&K Sound recommends an amplifier rated between 25 and 500 watts per channel that is stable with the speaker’s nominal 4-ohm impedance.
