M Series

Overview

The M Series models seeks to achieve as many of the performance attributes seen in the X Series as possible at a lower price range. The holographic experience and world class bass control are no problem for the M Series. The M4 Ultra and M3 achieve this high expectation.

M4 Ultra

$ 4,950 USD

In a historic move, the new M4 Ultra will be built to X Series standards of chassis design and quality. The massive 80 lb. structure and X4 Ultra woofers together provide thundering bass and liquid midrange for a new level of realism in the M Series. No expense has been spared in producing the finest M model ever made. Stunning 3D soundstaging and ultra-transparent reproduction await. The new M200 Silk Dome Tweeter renders uppers registers beautifully, without glare or fatigue. The thick aluminum base is machined from Kaiser aerospace grade material for high rigidity.

Introduced in 2019, the M3 Sapphire took what we had learned over the previous 2 decades and drastically upped the ante. The M3 quickly took a dominant position in the open baffle market and pointed the way to a dipolar future. The M3 is a 2.5 way, dipole design with twin 15 inch paper cone woofers. A special wide band treble driver covers the range from 600Hz to 40kHz. The ultra wide band operation offers very integrated and linear music reproduction, with the 3D projection of open baffle bass and midrange, allowing the speakers to disappear into the sound field.
