I originally bought this subwoofer to listen to some bass heavy music, but it is a shining star in my older home theater setup. I can't say how much I would recommend this woofer at this price point, it has made us enjoy old movies again like we are watching them for the first time.
I spent a good bit of time looking for a new subwoofer on Google (reddit) and the rsl speedwoofer was top of the list. I was looking at simmilar priced kliptch options, but I am very happy I went with the rsl after hooking it up. This thing is built like a brick shit house, and took several minutes to even get it out of the tripple cardboard box it was shipped in.
I will say it gets lost when hooked up to my old house speakers with 15" woofers, but it does a great job of filling in the actual lows vs my house speakers just moving air.
If you're on the fence, buy one, and ask your wife for forgiveness later. I tucked mine in a dark corner and got praises for how much better movies sounded before I was asked for a receipt.
