    Great Atmos height Speakers

    I’m running these for my front and rear Atmos height speakers, love the sound these produce, especially the folded motion tweeters(very clear without being harsh) Great price per performance!

    Great Atmos Speakers

    Basically my same review of the 4i's. I bought these for ceiling Atmos durround speakers. I was a little worried I wouldn't like them as I found a pretty negative review online. These definitely don't sound as good as my Motion 60i's but because these are really for special effects noises they are perfect. They definitely need to be crossed over at 80hz and you have to have a subwoofer with them. They also have a 1/4x20 lug in them as they are designed to be wall mounted. Worked perfect for our needs.

    Great surround speakers

    I use these as my two rear speakers in an Atmos setup. They provide great sound and have allowed me to hear parts of movies and shows that I was missing previously with my old speakers. They are a perfect combination of size, price and performance. I will continue to buy only MartinLogan speakers in the future.
