Looking for excellent sound without taking up much shelf or floor space? The MartinLogan Motion® 4i offers a powerful combo of musical performance and compact design. Use a pair as part of a stereo music system, or grab as many as you need for a MartinLogan surround sound system.

One of the reasons the Motion 4i sounds so good is its Folded Motion™ tweeter. This unique, accordion-style design is quick, accurate, and very smooth. You'll enjoy clear, natural sound throughout its frequency range. 

Since this speaker is relatively small, you may want to pair it with a powered subwoofer for deeper bass — especially for home theater applications.
