Motion B10 Bookshelf Speakers

The new Motion B10 bookshelf speaker uses the 5.5” woven fiberglass midrange with the new Gen 2 Folded Motion Tweeter. This model has a rear-firing port and is set up for single wiring. They have an impedance of 4 ohms with a sensitivity of 92db, which is very high for a speaker of this size.

The B10 is a relatively compact speaker designed to be used in a small to medium-sized room. We found them to produce a very wide and three-dimensional sound stage and like every one of these, with a stupendous top end. The highs are lighting fast but very smooth. You can listen to these for hours without any sense of fatigue. They had the best balance of bass in our testing about 1 foot off a back wall, but in reality, they still do not go very low with a rating of 56Hz. These will make a great main surround speaker or if you pair them with one of the fast Dynamo MartinLogan subwoofers. They can throw out a huge soundstage with the subwoofer adding in that missing last octave. We would, however, not recommend them as a full-range speaker in a larger size room as you will probably find the bass lacking.
