"Its bandwidth, narrowed to the essentials compared to "modern" sound transducers, leads to concentration on the essentials when listening. In doing so, the listener does not miss the slightest thing, but rather rapidly falls prey to a degree of sonic magic that must unfortunately be considered extinct, just like the perfect temporal cohesion of this loudspeaker, which degrades the vast majority of current multi-way designs to a sound puzzle with clearly audible interfaces. "
That's my opinion, having some listening experience with WE speakers, too. After hearing them, I've had zero strive towards such modern speaker constructions anymore. They just fail to impress me anymore but on the opposite, scared me with their inability to establish acoustic magic in the experience like the old designs did. Their qualities couldn't be analyzed by measuring them, just by auditioning.
