I own both a LFM1-EX and a Sunfire True Subwoofer. I can even take a pic of them side-by-side if you'd like.
The Outlaw is a much better sub, IMO than the Sunfire... not even counting that my Sunfire is dead. The Sunfire failures are a common problem, I should mention. I now power my sub with an external amp, but it is no longer in my living room, the Outlaw rules the roost at my home.
And you are looking at the Jr, not even the bigger Sunfire like I have.
