Lrsky, the field-coil powered Classic Audio Loudspeakers will do the same imaging and detail as the Sound Labs, without horn artifact. The speaker is 98 db and goes from 20Hz to 35KHz. If you search this website look for comments on the speaker from either the RMAF 2008 or T.H.E. Show 2009.
One thing to keep in mind is that most horns will not sound right with transistors- that in fact is where the 'horn sound' myth comes from. For more information see

Field-coils are the dynamic speaker equivalent of the powered Electrostatic Field in an ESL. In essence this gives the driver the same speed that an ESL can exhibit, and for the same reason: the motive field does not sag when the amplifier powers the diaphragm to move.
