Thanks for your reply. My question then becomes, if you set the QS-8 to small, then aren't you basically making the QS-8 and QS-4 equal? I mean, the only difference (other than the efficiency and ohm rating) between the QS-8 and QS-4 is that the QS-8 goes down to 60Hz. So if you set to small, then on most systems the crossover is at 80Hz thereby negating the QS-8's ability to go lower than the QS-4. In effect, wouldn't the QS-4 and QS-8 sound equal if they were set to small, since neither would be able to go below the 80Hz crossover?
