Yes a lot has been written about the passive/active debate.
In a nutshell, the math (on which all electronics is based) goes against you when you run a passive system. The Lightspeed is no exception. You can improve the situation slightly by using setups that operate at lower impedances, but then your source has to support that operation, which is not something universal to say the least.
OTOH active line sections with marginal design will be easily beaten by a passive setup. So if you want to boil it down, on the cheap use passive, if you want the best you will have to go active.
