Zu def 4 are they the best speaker made?

I have been a Zu fan for a long time starting with the presence and moving to Definition 3 then to Definition 4.

In my opinion if you like Americana, Rock music
Blues or Bluegrass, then these speakers with the right electronics and room, I really feel like the room matters as much as components.

these speakers lack nothing in my opinion you have great soundstage as well as intimacy and realistic bass.

i have tried a lot of different amps and preamps
But for me as Cobra from this site.  suggested a good 845 amp is a match made in audio heaven!

I'm using a Jhango passive and my 845 is a Larry Moore Monaco with some upgraded parts

Lampizator Dac and transport thru a MacBook Pro with Tidal and it’s simply amazing!!

for vinyl I have a modded table from George Merrill of Memphis Tn, great guy by the way.

and my phono pre is Heed quasar , nothing crazy expensive and I would put it up against anything I have had the pleasure to listen to.

my point is Zu makes a fantastic speaker on top of amazing customer service. But with the right gear they can sound as good as it gets.

i know that’s a bold statement but these speakers are so immediate and life like without any limitations that I can hear but it’s just my opinion.

Check them out for yourself, you may feel the same way.

Bache is posting measurements from 2002 that don't even work right (the speaker was lifted in air despite a downward firing port).

at least use Stereophiles more recent ones:

Keithr@   Position of Speaker dont important for reproduction midbass
Please read https://www.trueaudio.com/st_diff1.htm
This is a problem can be corrected by using  baffle step crossover
or multiply speakers , or using very big baffle

For those of you who are concerned about measurements. . .  The ZuAudio website (About>Downloads) has measurements made in my living room using my pair of Definition 4s; they are part of both the downloadable owner's manual (definition mk.iv owner's manual) and downloadable specs (definition mk.iv ad copy + specs).

I refer to main idea why the most of the single driver speakers
with crossoverless design get issue with baffle step or
Loudspeaker Diffraction Loss https://www.trueaudio.com/st_diff1.htm
it does not matter how the get measurement , especially all manufacture
put it manuals very flat response .  it is very clear if you provide
piano test.  It also explain why is    single or 2 way speakers with
wide baffle ( some vintage) sound better , them new narrow baffle

So, to sum up, ZU Def 4s are the best speakers. Done. This fact does simplify things as I'm sometimes asked, "Garcia, what are the best speakers?" Now I just say, "ZU Def 4s." It's kind of a relief really…now I can move on to other issues I've been neglecting.
