Red Aniline Dye


Incomparable ESL Precision

Ascent expresses the unique MartinLogan language of form and function. It embodies the look and break-through technology of its sibling—Prodigy—in a sculpted cabinet that is sleek, compact, and beautifully finished. Its all new design leverages both the MartinLogan CLS (curvilinear line source) electrostatic technology and our long experience in hybrid speaker system design. Ascent maintains controlled dispersion—for minimal room interaction—while providing outstanding dynamic range, imaging, and detail.
