MartinLogan's Motion series speakers are known for sound that's realistic and immediate without being overbearing or harsh. The Motion 4 bookshelf speaker provides smooth, musical highs, clear mids, and surprisingly rich bass in a compact, elegant-looking package. Equipped with an included wall-mount bracket, this speaker works great in a wide range of applications. Use a pair for stereo music in rooms where you don't want to sacrifice floor space. Or use four of these satellites for your front and rear channels in a high-performance surround sound system.
The distinctive sound of the Motion series starts with MartinLogan's Folded Motion tweeter. Rather than a dome or cone driver, this tweeter uses a pleated diaphragm that works like an accordion by "squeezing" air to create sound. It requires about 90% less excursion than a typical 1" dome tweeter, resulting in quicker response time and much lower distortion. The tweeter's controlled sound dispersion creates a focused soundstage with a real sense of presence. Music sounds amazingly detailed, but smooth and effortless, without a trace of harshness.
A stylish, curved cabinet with a unique folded port
The tweeter is coupled here with a 4" doped paper cone woofer that supplies accurate mids and lows. The Motion 4's eye-catching curved cabinet is finished in classic high-gloss piano black, and it hides a unique folded bass port that helps reinforce the low frequencies and improve sensitivity. This speaker's subtle, modern lines complement just about any décor. If you're mounting it high up on your wall, you can invert it to aim the high frequencies downward toward your listening position.
Be sure you get enough bass
For even better bass — and especially for high-impact home theater — we recommend a powered subwoofer, like one of MartinLogan's excellent models.
