You might want to ask SVS about the 2 PB-10s; that's alot of room to fill with LFE. Matter of fact, you might also ask if the 20-39 PCi is enough. At the very least, the 25-31 might be a better choice because of the additional headroom it provides.

Also, a warning - the 20-39 PCi is big, I mean REALLY big. Even more so if you keep it in the box. I'm not sure what you are driving to Florida, but if you plan on bringing it back in a car, you better make plans to strap the wife to the hood . If you can get it into the car, there won't be room for much of anything else.
