why is that? A sweep from 10hz to 200hz through the lfe channel over 2.5 secs wont hurt a subwoofer just know the limits of your system and dont run a 20hz sine for more than 2 secs to be safe to protect the VC. But as far as a sweep at 100 db or more on subs that can output 115 db is almost a joke unless doing it continuously over and over.
How else does one check out how their systems for compression and output?

There are movies that are more dangerous to subs then a frequency sweep test and SVS subs are very well protected from high level output spikes so its more about keeping heat from destroying the voice coils which takes time to occur in this case.
