    Great quality sound! Zero disappointment. Thrilled with the purchase. Worth every penny.

  • Rated 4 out of 5 stars

    Great choice for space constrained

    Needed a center channel that was shallow and this was one of the few available. The sound quality is top notch, my only complaint is I would like a bit more bass. Feels like they could have made this wider and thrown a larger (or more) woofers into it. That said, I now have ML’s all around - Motion 35XTs for front, this for center, 4i’s for surrounds and sub. Combo sounds great overall.
