Power Range

Power range is the range of input power in watts RMS that a loudspeaker is designed to handle. While using an amplifier within this range ensures the nominal performance , inputting a power that is higher than the max wattage can result in a damaged speaker.

BP-9040 and R700 has the same power range of 50-300 watts.

Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters such as Impedance, sensitivity and system efficiencies.

Input Type and Bi-Amping / Bi-Wiring

R700 features Post posts which make bi-amping or bi-wiring possible. BP-9040 has a 5-Way post, RCA which doesn't feature bi-amping/bi-wiring.
