A speaker will let you know if it is being abused, the key
is to use common sense. Do not worry too much. Do not
really fear, the speakers or the receiver.
It will take a lot to distort the HTD speakers - they are
not wimpy, and will not easily faint >> Overall, speaker
wattage does not mean a whole lot to me.
The HTD speakers can even be driven with a higher watt
receiver than the Denon receiver. > Most people do not
use, or need all the power that the receiver has.
The HTD Level Three speakers can play seriously loud for
their size, I can play them loud in a 20 X 30 open room,
and play them louder than I care to listen. They also, do
put out a lot of bass, and can/do go lower than 60 hz. HTD
even recommends a 60hz crossover for the Level Three, to
your subwoofer. >>> However most of us, would do 80 hz
to begin with.
The Level Two also has good bass response, and will go
down nicely, to crossover to a sub. They are not a wimp.
