Summary: I purchased this to compliment by B&W 685's. it more than did the job. I had it set at about half power, and it was perfect for both music and movies, with an emphasis on movies. For the price I highly recommend this subwoofer. It is worth every penny.
Summary: I really like the velodyne quality. I have had one impact 12 for a few years in my media room. I just decided to upgrade my living room so I got rid of the Bose and went with another impact 12. I would have given it five stars but this product wasn't working out of the box. When I opened the speaker box I found that velodyne hadn't connected the speaker inside of the box. Other than that it is still a great product. I stand by this brand.
Excerpt: Great on movie soundtracks. Using the Impact-12 in a 15x20 room. It took about 2 weeks to break in but after that time frame and a bit location testing it works well. I also purchased the Impact-10 for another smaller room. Had them side by side during the break in period. The Impact-10 is very close in output to the Impact-12 and may be fine for most people. The Impact-12 goes just a little lower but not by much.
Summary: I have owned a Klipsch LF-10 sub, Velodyne HGS-12 sub, Paradigm PW-2200 sub. and a Velodyne DD-15 subwoofer. I purchased this subwoofer because of my experience with Velodyne subwoofers. This sub. was a terrific addition to my sons Klipsch HT-500 / Yamaha Reciever combo. purchased for my sons room. The Velodyne easily tripled the bass output and quality over the base subwoofer that Klipsch sells with the HT-500 set.
