Since I design and sell subs I'm a little biased. Good LF performance is all about rooms. Once you get under about 200Hz the room really starts to dictate what is going on. Matching subs to main speakers has also traditionally been done horribly. Since the room is having it's way at these frequencies manufactures have been able to punt on designing a proper crossover between the main speaker and the sub.
A tool like the SMS-1 (Velodyne) is a great investment. If your smart, you can also use it's built-in room measurement tools to optimize the placement of your main speakers. You don't get to keep it in the loop but just having the measurement gives you more information about where to best place main speakers. In an ideal world, we would have room measurement and correction for every device and then a system measurement (because once you combine them in the room it changes the in-room response). Typically a one or two notch filters is all that is needed per LF device. Getting the proper measurements and knowing what to correct and how much is the key. Anyhow... just thought I'd chime in.
