MartinLogan Motion 40i Floorstanding Speaker - (Each) Gloss Black

 

The secret to Martin LoganMotion 40i's outstanding performance lies in its Folded Motion® tweeter, 5.5-inch aluminum cone midrange driver, dual 6.5-inch aluminum cone woofers with a rear-firing bass port, and a proprietary Vojtko crossover network. The next-generation Motion 40i delivers a similar wide-open soundstage, sublime high-end detail, smooth midrange accuracy, and deep bass extension from a new design that improves on the original.  This double woofer design produces vibrant, accurate deep bass performance. Motion 40i delivers the classic broad soundstage of the Motion Series from a newly designed enclosure enhanced by the slightest of modifications, including the drive-stabilizing dust cap design, stiffened motor suspension, and low-mounted woofers to reduce an acoustically harmful phenomenon known as floor bounce. The speaker's enclosure sports a reinforced baffle and a fabric grille. Available in three stylish finishes: Gloss Black, Matte White, and Red Walnut.

A solid mid- and low-frequency foundation

MartinLogan uses aluminum cones for their unique blend of lightness and rigidity. A 5-1/2" woofer keeps those crucial midrange frequencies clear and neutral, so vocals sound almost as if the singer were in the room. Two 6-1/2" woofers ensure the Motion 40i goes plenty low. The rear-firing bass port helps efficiently enhance bass response without adding distortion to this speaker's clean performance.

 

Detail and precision from the Folded Motion® tweeter

Perched above the Motion 40i's midrange woofer is the source of this speaker's impressive high-frequency performance — MartinLogan's acclaimed Folded Motion tweeter. Its pleated diaphragm works similarly to an accordion by "squeezing" air to create sound. Because it requires almost 90% less excursion than the typical 1" dome tweeter, response time and distortion are drastically reduced. The diaphragm's increased surface area also provides wide, yet controlled sound dispersion to create a realistic and highly accurate soundstage.

 

Unique crossover network

Motion Series speakers feature proprietary Vojtko™ crossovers, named after MartinLogan's chief audio technologist, Joe Vojtko. "A Vojtko crossover isn't so much a set of design requirements as it is a philosophy," the company explains. Each speaker's drivers are carefully selected or designed to operate within an intentional frequency range and specific performance parameters. That allows the crossover networks — built from high-quality capacitors and resistors — to be clean and uncomplicated.
