    Audiophile performance without breaking the bank

    These compact satalite speakers are really just that good fir the price. The folded motion tweeter gives you a crisp and airy sound with tons of detail. The sound stage is very large for this size of a speaker the ported mid bass has great low end that match some of the larger speakers in the martin logan range. If you do consider to purchase these get a subwoofer to help with the lower frequencies. These are a must have for anyone getting into speakers I cant give them any higher praise than that.

    Sweet Little Speakers

    I love the purity of the ribbon tweeters in the Motion 4 speakers. Since I like to feel the bass, I would only purchase them paired with the Martin Logan Dynamo 8 sub for a medium sized living room setting. The high end is delicate and smooth for acoustic music, but still have a decent edge for harder rock. I wouldn't recommend for hip hop styles with explosive bass energy, but if that's your preferred music genre you probably would be looking at this speaker anyway1

    Great for Heights and Good for Surrounds!

    I use these speakers as my surround and heights for my theater. Love the style of them and they do sound great. They lack base, but for surrounds/heights its not too important. They have enough to get the job done thats for sure. I plan on upgrading them soon though. I'm going to keep them as heights but not as surrounds. For Height/Atmos, theyre perfect!

    ML surrounds

    Was able to find a steal of a deal on an open box pair. They're being used as side surrounds in a ML 5.2.4 configuration. They sound great to my ears. Blend well with my Motion 40 and 50. Install was easy. The bracket they come with doesn't allow you to angle the speaker. Works well in my application still. Seem easy to drive with an older Marantz 6013. Solid build and clean sound as surrounds or fill.
