Hello, I just purchased a SVS 20-39CS+ w/Samson 1000 watt amp. I orginally had a Velodyne CT-120. When I first hooked (before calibration) it up and took a listed I was not impressed like everybody was talking about in this forum. Packaging? Packaging of the sub was first rate. I realized how much effort was put into the box when I opened it for the first time. The amp was also packaged very well and everything was in perfect condition (as it should be), but you can never trust UPS. Hooking it up: I read the directions to the T and it was so easy that my wife could do it. She is not a huge fan of my hobby. I like that you can use speaker wire to hook the sub to the amp. The reason is that you can move the sub anywhere you want. Nice job Tom! Movies Before calibration and actual placement the sub is not that much better than my Velodyne. After calibration? WOOOOOOOWWWWWW!!!!!! This sub really shines and I demoed about 10 movies this past weekend. I put in the Haunting and holy crap! I have never heard or felt bass like that before. This is the only DVD where the clip light flickered (for a 1/4 of second), it stays mostly on the -20dB level. Then I put Jurassic Park III and another Wow!!! When T-rex and the other big one fights or walks, the bass is simply amazing. Overall, movies is where this thing shines. MusicAnother area were the sub rocks. Bass is clean and tight. It never seems to be over-bearing or fatiguing to your ears. Overall, nice addition for my wife's musical tastes. Overall: This sub just keeps rocking and does not disappoint. The bass is amazing but what really gets me is what you feel. My old Velodyne does not come close in this department. Actually most subs do not even come close to putting out the sound pressure that the SVS can. My friends are dying to come over and hear this thing. I told them to get ready to hear/FEEL some bass. Thanks Tom and Ron for all your help with my constant emails. Your work will never go unappreciated on this forum and I now know why. This sub rocks!
