With the Vandy 7s the Thunder will be drawing current above and below
180 hz which is the crossover point between the mid-range driver
and the subwoofer. The sub-woofer amp boosts the frequencies below
the crossover point back to flat and rolls off the subwoofer above the
crossover point. So, as you can see, the current will be limited unless
called upon. Right now I have about 20 hrs on the Thunders. It does
seem to me that the there is greater clarity in the bass region, Above the
the crossover point the midrange will slope up while the subwoofer
slopes down. Below the crossover point the opposite takes place. Break-in will take awhile.
