Probably not a popular opinion but I have owner a depth and dual Abyss subwoofers. The Depth is one of the best musical subwoofers I have ever heard. I have also owned a couple of SVS subwoofers and they are one of the top of the food chain sub companies for HT. 50/50 mix I would definitely lean towards the dual SVS subs. The Depth really doesn't get much respect around these parts, especially at it's MSRP price range.
