Only 58lbs?

Was checking out the specs for the LFM-1. Was surprised to find that it only weighs 58 pounds. Now, I don't have much experience with different subwoofers, but that doesn't seem very heavy to me. My center channel speaker weighs nearly that much. Would a sub that is only 58lbs have problems when pushed to extreme SPLs? Would it vibrate too much or worst case actually move around a bit?

I don't think that ~60 pounds is all that light for a sub. My mains are close to 70 pounds, but they are also almost three feet tall. There are a number of powered box subs weighing around 60 pounds or less. SVS's cylinder subs weight a lot less (I couldn't find any numbers, but having moved mine around some I'd guess it's comparable to a Model 1050 -- 35 pounds, maybe 40 tops). It shouldn't be a problem at all if the cabinet is solidly built.
