    I have had this sub for a month now and it has made a difference to the over all sound of movies and some TV shows. Explosions rumble the floor and furniture in action films and bass is plentiful overall. Bought this unit primarily because it works with Anthem Audio's ARC software and as I have an Anthem receiver thought it would be a good fit. Set up was simple, as close to plug and play as you can get. The ARC software picked it up right away. You can also run it without using ARC and there is an app that lets you make adjustments on the fly. Most subs are not much to look at but this unit in gloss piano black is an exception but it does attract dust so beware. At 300 watts it is powerful enough for my small living room. Happy with the purchase especially since it was on sale.

    Amazing sound and build quality! The actual woofer itself is absolutely beautiful! A true work of art. Very small but packs a punch. I love it.

    Based on the description when I was deciding...I thought it had wireless built-in. My fault for not doing better research. It does sound really nice though.. although for the same price I could have gotten the SVS. Would love to do a side by side comparison.

    This is an amazing sub from favorite audio company, especially for the hifi price, and e app connectivity works really well and I never had any issues. May not be perfect for everyone but it was for me.

    Installed as part of a new Home Theater system and the entire package is awesome. My in home consultant was responsive, listened to my objectives and installation was handled by a pro. Exceeded expectations.
