I have the Yamaha RX-V1700 i have brand new fronts and center and 2 new rear surrounds. I am awaiting my sub which is on pre-order. What should at set my receiver at for a setting. LARGE? or SMALL?. What should the crossover be set it also? Because i obviously will be having no sub to output any LFE. I don't want to overload my other speakers with to much bass responsibility. Any suggestions?
