Customer Comment

Steve,

I just finished the subwoofer and it sounds great. I attached a couple of photos so you could see what it looks like. I still have some pictures of the assembly on "roll film" that I have to get developed. I can't say that the amp provides enough power to crack plaster (like theShiva emails clients seem to love) but that isn't why I bought this unit. I have the volume set to about 1/3 and the room still shakes impressively when an explosion goes off. Yesterday, I watched Hunt for Red October and the soundtrack has the deep rumble of machinery going on throughout the submarine shots. This was very nicely duplicated by the subwoofer. My wife wasn't very happy about the concept of a large subwoofer in the living room when I first told her about it but when it was finished she told me to put it out in the room instead of behind the couch. When I get some more photos I will send them to you.
