Correct ... without a LPF the sub will be amplifying full range, not
an ideal situation, but OK. *Almost* all Powered subs have their own
variable LPF. (normally from 40-120Hz) Some THX subs are permanently
fixed at 80Hz, most will have a phase switch (some have a variable phase),
some allow line-in only (low level), others have speaker in (high level),
many have both.
I use a switchbox that allows me to use the lineouts chained from my
power amps to the sub for music listening, and then I can switch it
to the variable LFE output of my amp for movies. Automatically gives you 2
bass levels without having to adjust the volume levels on the back
of the sub (which is a pain).
Cheers GC
