Polar Response

The enclosure shapes are not just the whims of external design fancy, but combined with the transducer systems to produce an acoustic polar diagram that is a dipole at high frequencies and gradually shifts into an omni-directional pattern for the low frequencies. As a result oif carefully engineering, the polar diagram is very smooth and without any lobing: The reverberant sound field excited by a loudspeaker within a room is in effect the frequency response of the indirect emissions from the loudspeaker: If this indirect, or polar response is not clean and even, then the reverberation heard will be coloured and will add clutter to the overall imaging. A secondary benefit of a good polar response is the reduced requirement for acoustic treatment for the room: normal room reverberation in itself does not reduce the ability to listen accurately, so long as the reverberation is excited in a mimic of the natural trigger, in other words triggered by a smooth and even polar response.
