I think this answers my question, Charles. What I don't know is whether or not the LFR actives are as pin-point as the non-LFR v4.
"Omnidirectional speakers have had a cult following among music lovers ‘in the know’ for years. Why? Because their wide-open 3D soundstage transforms your room into a huge concert venue. Traditionally they have done this at the expense of the pinpoint detail, but now you can have both! By using a Digital Signal Processor (DSP) between the front and rear drivers the LFR series of omnidirectional speakers have both a wide-open 3D soundstage and pinpoint detail."
