yes, setting them to small just diverts the freq. below the crossover point to the sub.
However, if you set the fronts to large, and change the sub setting in the denon to "lfe+main" then the frequency below the crossover will be played by both the mains and the sub. This will likelly give you too much bass but might be worth trying out.
If the fronts are set to large, and the sub is set to "lfe". then the sub is not used at all for 2 channel music. (unless you are in surround mode and then only the lfe and the low frequency to any small speakers are sent to the sub.)
Ian from axiom stated that any "break-in" happens nearly instanteously.
