i would never, never send a sine wave at -1 or -5 dBfs.
chances are your speakers will break down quite fast, specially the tweeters.
this has nothing to do with crossovers.
sine waves are not the same kind of animal as music or loud movies, they vary continuously in frequency and amplitude, contrary to sines waves.
sine waves are very dangerous IF you don't know what you're doing; they are continuous amplitude waves, and don't let the speaker breathe to cool down.
