    The base works perfectly. Visually it look great as well and is not obstructive or in the way. I love the sound and the overall performance.

    This little sub packs a lot of punch. I have it installed in my home theater and my seats vibrate. Didn't expect so much power from a little box.

    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.

    Blue Tooth fun

    Recently purchased a Martin Logan ESL, which needed help in the lower base range. This ML 800X blended with the ESL, which had only one 8inch woofer. The Blue Tooth remote for the IPhone is alot of fun to use, but can be very frustrating at times as you must close the app, before you turn the iPhone on.

    This sub offers the perfect compliment to our home theater. It's just enough to feel the sound and doesn't bottom out at the real deep lows

    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.

    great for a small room . Quality is great for volume comparison when set to auto. you turn the volume up on sub it starts to sound distorted. It is over priced is my only con for it.

    The app (Martin Logan and ARC) sounded promising

    Still trying to get it integrated with my KEF LS50 Meta speakers, so I might become more sanguine about it. The app (Martin Logan and ARC) sounded very promising, but didn't do much for my set-up. It almost seems like they're more useful for ML's marketing than real world benefits. I've tried also a KEF 10 Kube, which was sounding much better - I might go back to it and return the ML. The quality of the built is NOT that of a $900 sub. One of the feet already came out when I've tried to take it out to change the speaker orientation to front firing. It seems the body is made of cheap particle board, not MDF.
