MartinLogan Motion 40 Speaker

The Folded Motion tweeter uses a pleated diaphragm that moves air much faster and with less excursion than a traditional dome. This design significantly reduces distortion and provides a much clearer, more detailed high-frequency response.

Yes, the Motion 40 is compatible with 4, 6, or 8 Ohm rated amplifiers. With a sensitivity of 92 dB, they are relatively easy to drive, though they perform best when paired with an amplifier capable of handling their 4 Ohm impedance.

The dual 6.5-inch aluminum woofers provide a solid frequency response down to 40 Hz, which is sufficient for most music listening. If you are building a home theater system and want deep, cinematic bass for action movies, you may still want to add a dedicated subwoofer.

Yes, the Motion 40 features custom 5-way bi-wire tool-less binding posts. This allows you to use separate cables for the high and low-frequency sections of the speaker if your amplifier supports bi-wiring.

Each speaker measures 42.5 inches tall and 12.8 inches deep. Because they feature a wide 80-degree horizontal dispersion, they are designed to fill a room with sound, but you should ensure you have enough clearance to position them away from walls for optimal imaging.

By using a dedicated 5.5-inch aluminum cone for the midrange, the speaker can focus specifically on vocal and instrument clarity. This prevents the bass woofers from having to handle the midrange frequencies, resulting in a cleaner and more realistic soundstage.
