What would the ideal speaker sound like?
 

We respectfully quote Robert Harley in Issue 229 of The Absolute Sound:

Let’s indulge ourselves for a minute and imagine that we could conjure up the ideal loudspeaker without regard to physics or the limitations of today’s technology. Our fantasy allows us to specify the transient speed of a full-range ribbon, but with the weight behind those transients provided by moving-coil drivers. We’ll take the transparency of an electrostatic with the dynamic contrasts and ‘jump factor’ of a horn design. Since this is all wishful thinking, we can specify no horn colorations to go with the horn-like sense of immediacy and dynamic verve. We’re free to order up the visceral bass weight and body of a large ported enclosure accompanied by the dynamic agility, textural resolution, and pitch definition provided by a small sealed enclosure. And while we’re at it, our dream speaker will exhibit no box coloration, have high sensitivity, and be an easy load for a power amplifier.

Do Bob’s Amazing Line Source speakers approach this idel?  Many listeners — and happy, satisfied owners — think so.
