MartinLogan Motion MP10

Motion MP10 is the shallow two-way speaker in MartinLogan's Motion series: a Folded Motion tweeter and a 14 cm mid-woofer in a cabinet 12.7 cm deep, to stand on a shelf or fix to the wall with the bracket included. It is offered as a pair.

Motion MP10: on a shelf or on the wall

Motion MP10 is among the most versatile models in the Motion series: just 12.7 cm deep, it works as a slim bookshelf speaker or goes on the wall with the bracket provided. On a wall it can be fitted parallel to the surface or upside down, so the baffle looks downwards: the right position when it is installed above ear height, for instance as a surround or effects channel in a home cinema system.

The slim depth is down to the Stealth reflex port, formed in the back so that it does not get in the way of the bracket: according to MartinLogan it permits low-frequency output comparable to a conventional bookshelf speaker of twice the depth. The stated response runs from 81 Hz to 25 kHz within 3 dB, sensitivity is 92 dB and impedance 5 ohms; the suggested amplifier lies between 20 and 200 W.

The drivers are those of the Motion family: a 26 x 36 mm thin-film Folded Motion tweeter in Gen2 Obsidian form and a 14 cm woven glass-fibre mid-woofer, crossing over at 2,100 Hz. The tweeter's waveguide opens output to 90 degrees in both planes, so the sound covers the seating area well whatever the mounting point. The cabinet has a 35.6 x 20.3 cm front and weighs 4.4 kg.
