I have decided to upgrade my 7 year old subwoofer and I have narrowed down the list to two contenders and I am hoping for a little input from forum members. I was hoping to get a sub that can play at least 20 hz and one that will add some more feeling and impact. I was also hoping to find one for under $750 but I could go a little higher if I had to, and right now I see the HSU has their VTF-3 MK2 for around $700. I was also looking at the SVS PCi series. Have there been any direct comparisons for these two companies? I know that SVS has a strong following here on the forum and I do not want to upset the apple cart, I am just looking for the most bang for the buck (Literally). My room is small and the SAF is not a factor, tube or box does not matter. Any help will be greatly appreciated.
