No one mentioned time coherence. Quads got me interested in coherent speakers more than ½c ago.
Vandersteens are pretty good. Maggies can be if set up properly. Spice TC-50 on stands with sub in a good room can transport you.
Tri-amped, time corrected Eminent Tech LFT-8b w dual subs are outstanding! 😉
With 650 wpc, they will make you duck in the finale of the 1812 or have you stomping along with Queen’s "We Will Rock You". Jaqueline du Pre and YoYo Ma live here!
Small string ensembles in a good room are extremely rich in coherent harmonics.
Speakers plastered on a flat plate are never going to cut it.
