A39 – It is often assumed that excessive amounts of power are required to drive a dipole woofer, because of the necessary 6 dB/oct acoustic roll-off equalization and additional boost required for drivers with Qts below 0.5. In fact, equalization does not change the power requirement. It is a driver’s cone excursion for generating a desired SPL which determines how much output voltage and current an amplifier must be able to provide. I will illustrate this with an example example for two drivers, a Peerless 10″ XLS 830452 and a Seas W26FX001, when driven from amplifiers with 180 W and 60 W into 8 ohm specification. Go to the Power amplifier limited SPL for a dipole woofer page to find the results. See also a related analysis of SPL limits for a closed box woofer .
