[QUOTE="Shonver, post: 545373, member: 34"] They are closely related. Except that power response is polar response considered over the full range, as opposed to a few frequencies. You can imagine that if you stacked slices of polar response on top of each other (totem-pole style) at points of increasing frequency, you would end up with a 3D representation of how the speaker radiates into space. Speakers are typically designed from on-axis response, which can be designed to be flat. But how the speaker interacts with the room is dependent on its frequency response of-axis. Even if it is uneven off-axis, it is important that the transition from (flat) on-axis be as smooth as possible. Of primary importance here is the matching of polar response between drivers over the crossover region. To achieve this, there are a few approaches: judicious selection of driver size (diaphragm diameter) and acoustic transformation (e.g., waveguides).
