The words affordable and MartinLogan may appear to be antonyms, and that’s certainly true for the company’s electrostatic speaker offerings. However, its Motion Series speakers combine folded-ribbon tweeters with traditional woofers providing a surprisingly wallet-friendly entry point for the brand. At CEDIA 2017, MartinLogan debuted five new models in the Motion Series: The Motion 2i, 4i, 6i, 8i and SLM X3.
The Motion 2i ($180) and Motion 4i ($250) are bookshelf speakers that are designed to be a good fit for use in a surround-sound system, as freestanding bookshelf speakers, or in wall mount applications. They can even be hung upside down for placement high up on walls, for example when used as height speakers.
The Motion 2i features a 1″ x 1″ Folded Motion tweeter (i.e. AMT for air-motion transfer) and a 3.5″ mid/bass driver. It has 86 dB sensitivity, 6 ohms impedance, and handles up to 100 watts. The rated anechoic frequency response is 115 Hz to 23,000 Hz (+/-3 dB). This speaker measures 4.75″ (W) x 10″ (H) x 4.625″ (D). Meanwhile the Motion 4i ups the tweeter size to 1.4″ x 1″ and uses a 4″ mid/bass driver. It has 90 dB sensitivity, handles 150 watts of power and the impedance drops to 4 ohms. Frequency response is 70 Hz to 23,000 Hz (+/-3 dB) and the 4i measures 5.625″ (W) x 12.625″ (H) x 5.75″ (D).
The Motion 6i ($280) and Motion 8i ($400) are larger models featuring a symmetrical design that are also suitable for use in surround-sound systems. They can be used freestanding, or mounted on a wall. When used on-wall, you can mount them either vertically for left/right/surround channels, or horizontally when used as the center speaker.
The Motion 6i sports a 1″ x 1″ Folded Motion tweeter and dual 3.5″ mid/bass drivers. It has 89 dB sensitivity, 6 ohms impedance, and handles up to 130 watts. The rated anechoic frequency response is 120 Hz to 23,000 Hz (+/-3 dB). This speaker measures 17.5″ (W) x 5.25″ (H) x 4″ (D). 4i ups the tweeter size to 1.4″ x 1″ and uses a 4″ mid/bass driver. The Motion 8i has a 1.4″ x 1″ tweeter flanked by a pair of 4″ mid/bass drivers. Sensitivity is 89 dB, impedance is 4 ohms, and frequency response is 70 Hz to 23,000 Hz (+/-3 dB). This speaker measures 22″ (W) x 6.625″ (H) x 5.25″ (D)
Last but not least is the Motion XLM X3 ($1000), a 3-channel passive soundbar. I don’t currently have access to specs but I’ll share ’em if I get ’em. That’s all for now.
