Hello, I was wondering if anyone is using the Cambridge SoundWorks Newton Series P300HD Powered Subwoofer. Cnet.com gave it great reviews. http://reviews.cnet.com/separate-speakers/cambridge-soundworks-newton-series/4505-7869_7-32117750.html?tag=prod.txt.2 I recently purchased the Outlaw Audio LFM-1 Plus Subwoofer. It sounds awesome but it vibrates a little too much. I have some neighbors and thus need to keep the vibrations down. I also have hard wood floors which I don't think helps. I was thinking the cambridge subwoofer could fix the job and still produce a good base response. Thanks for your feedback. John
