Absolutely love this subwoofer and having two isn't two much. I owned a 12" Polk prior. I own a complete Martin Logan speaker system. I waited 2 years for any of the Martin Logan to go on sale. Great Magnolia room Tech support and advice.

I am blown away by this subwoofer. So immersive and lifelike, that I almost feel like I’m at the movie theatre. Don’t be fooled by the wattage, it packs a definite punch...a great investment!

A good value for the money. The sub completes our sound system by adding a good bottom (base) to SACDs and movies.

Within a year, the sub stopped performing and the speaker had to be replaced. It broke with only minimal use at low volume and made a constant humming. I called the manufacturer and they sent me a new speaker which was very easy to install. Problem was fixed and it was not an internal electrical issue.
