Martin Logan Montis Reserve ESL Series Black Floor Standing Speakers - MTSBLBAD

Introducing Montis, the latest evolution in the MartinLogan Reserve ESL Series. Following in the footsteps of our award-winning flagship hybrid ESL speaker, the Summit X™, Montis blends legendary sound with sophisticated styling. Years in the making, the Montis builds on a number of unique MartinLogan manufacturing techniques and materials; XStat and AirFrame™ technologies, vacuum bonding, MicroPerf stators, a Curvilinear Line Source electrostatic transducer, dipole sound radiation, a low-distortion aluminum-cone woofer, advanced Vojtko filtering, a 24-bit Vojtko™ DSP engine, and 100-Hz level control.


  • Largest Hybrid XStat™ Transducer
    The electrostatic transducer used on the Montis is our largest hybrid electrostatic panel. This large panel size allowed our engineers to lower the crossover point to 340Hz, bringing more of the electrostatic clarity into the critical midrange frequencies.

    The XStat transducer features advanced MicroPerf stator technology giving the latest-generation CLS™ (Curvilinear Line Source) electrostatic transducer almost twice as much exposed diaphragm surface as a traditional electrostat of the same size. This dramatic increase in effective radiating area translates to the highest levels of efficiency and an effortless, unlimited dynamic presentation.

  • 24-Bit Vojtko™ Digital Signal Processing (DSP) Engine
    MartinLogan's dedicated in-house design and engineering team created an extremely precise 24-bit Vojtko DSP engine in conjunction with a powerful 200-watt class-D amplifier to deliver a stunningly detailed low-frequency performance reaching down to 29Hz—uncommon in cabinets this compact. DSP allows complete control and performance optimization over the low pass filters, woofer equalization and limiting functions, all of which are mapped mathematically in the digital domain. Additionally, integrated low-frequency equalization below 100Hz further enhances bass performance by allowing precise tailoring to adjust for individual room acoustics.

  • Advanced Vojtko Filtering
    Proprietary Vojtko filtering technology is utilized for Montis' electrostatic transducer. This audiophile quality network, derived from the CLX, is carefully hand-built using precision point-to-point wiring, polypropylene capacitors, massive air-core coils, and a custom wound toroidal audio transformer—flawlessly preserving micro-acoustic subtleties while effortlessly handling the broadest range of dynamics contained within even the most demanding sonic source.

  • Hand-Rubbed Wood Finishes
    Initial shipments of the Montis will be available in 3 hand-rubbed, real-wood finishes; black ash, dark cherry, and new for 2011, black cherrywood. The new luxurious High-Gloss Black Cherrywood finish has deep cherry undertones and appears almost black in low light, giving them a unique and understated elegance.
