Ok well I decided to get rid of the perfect and I bought my center channel with it. But I still need a good sub. I am very interested in buying the SVS PC-Ultra. I just dont have $1200 to drop on a sub. I have seen the new shiva kit for $300. That looks pretty cool, then I could get a good $200 amp and be done. But I have already been corrupted by SVS. I have heard how awsome they sound. But I know that they also started with a bunch of DIY sub guys. Now some people tell me DIY is the way to go. Can I get SVS quality in a DIY sub??? Because it does seem like a cheaper route. Plus it would be cool to tell people I built that wonderful sub you are hearing. Well I am just looking for some suggestions, and options for me. If anyone has any ideas please chime in. Thanks again.
