Hi all,
I've got a pair of Vecteure premiere loudspeakers . Those speakers were introduced in early 80.and were designed by Yves Bernard Andrè .  I still enjoy those speaker that look like some little Spica . Those loudspeaker even if are  not the latest word in details provide outstanding image and palpable bass. What really like in those speaker is the "effortless driving factor ". I mean that the amplifier feels always  at home with them . A friend has  told me that Yves Bernard Andrè simply revised the
"the spica design"  but I'm not sure .
I've always wanted to know something more about them but I've never  found any literature . Can someone let me know something about those speakers ? Could be what I've called "the effortless driving factor " nothing less than a good " Crossover"  design ? If so could someone indicate other examples of worthy "crossover design" .
