Zu Druid MK IVs vs. Essences

Unless you guys have comments about Essence vs Druid, then why are you posting here? Have you heard either one? If so could you put your comments in a constructive way, vs just arguing the same point for every Zu thread that pops up? Please, give us all a break and allow those of us who want a discussion have it.

Hi,
Docks which particular Zu models have you listened to and with what amplifier? Did the audition take place in your system, dealer showroom or was it at a show? What did you think?
Thanks Much,

>>The floor excuse just doesn't cut it.<<

If you don't understand how Zu's proprietary acoustic impedance model works, and how their full range driver is affected by it, then your assessment of the "floor excuse" is invalid. This isn't a multi-way speaker with a cardboard tube port we're discussing, so it doesn't behave like one. Hear it properly installed and you'll also hear that the speaker doesn't sound like the graph. And certainly no speaker/room combination in normal domestic construction has flat response. The speaker and the room cannot be divorced from one another. Attempts to measure speaker response in a non-interactive room are irrelevant to what you'll hear if the test is conducted with the speaker in a position where one of its critical working elements is removed.

More important, no current production Zu speaker has so completely an unmitigated dependency on being placed on a floor to perform well, though to varying degrees some kind of resting surface is advised.

docks - your claims on the druid response are equivalent to removing the tube port in a 'conventional' speaker, measuring it, then mocking the speaker's response.

Zu complained to soundstage about those measurements BEFORE they were performed, or at least released. Soundstage responded that all their measurements were done according to the same protocols. Nearly a decade and several iterations later, the misleading graphs still haunt the speaker, and I'd argue the entire line.

I owned the Druids and enjoyed them quite a bit, then the Definition 1.5's, Pros, and now the 2's. I'm off the merry-go-round. I hope you can be so lucky some day.

The impedance and frequency plot shows that the Zu Druid is a Paul Voight type design.The notches in the bass are caused by line harmonics cancelling the output from the drivers front. The distance from the floor will make a 3 dB difference at certain frequencies but noway nohow can this explain a 20 dB notch. The erratic response in the midrange is likely due to the whizzer cone.
