I always like to harp on the fact that, on-axis, the SPL of a dipole is, at the "dipole peak" +6dB compared to the same driver in a closed box (of any size, e. size modeling. So every 1/3 octave of bass you ask of an Open Baffle speaker demands +6dB which requires 2X the excursion and 4X the power. k. Apr 20, 2016 · One thing to remember.
