Blindfold Speaker testing

your using youtube videos to judge bass response.

im out

murphythecat,

YES! Using youtube to judge anything except, perhaps, appearance makes no sense at all.  On top of that, making any kind of universal judgment based on anything less than extensive personal experience is also nonsense. 

I agree with you that most wide range drivers are best used in multi-way systems.  Such systems, done right, will retain the immediacy and great presence in the midrange while sounding fuller, smoother and more refined than most single driver systems.  I think having the crossovers come into play well outside the heart of the midrange is a big help.

I first used YouTube videos to listen to Koetsu Black Goldline before buying. Let There Be Sound! lists the components used. https://www.youtube.com/watch?v=M4m3UTQkUVU Listening to several of these allowed me to compare this Koetsu with some others, as well as hearing the Herron phono stage.

Here is my system https://systems.audiogon.com/systems/8367 Every single component you see was purchased on the basis of reviews and/or YouTube "auditions". None of this has been brought home for audition. I have never in all that time (now well over 16 years) felt the need to send anything back. Far from it, everything has performed well beyond expectations.

Study this system. When I say every single thing, I mean every single thing. Conqueror tone arm. Verus motor controller. Herron phono stage. Melody amp. Tekton speakers. And a whole slew of tweaks too numerous to mention.

Next I would invite you to read the listener comments.

Finally, you might want to reconsider your use of the word, "nonsense".

I’ll talk for myself. I have owned and heard some of the most reknowned wideband drivers ever built. I do agree they excel in the mids. but every wideband Ive ever had or heard, needed at the minimum a supertweeter for over 8khz and subs crossed quite high.
so while they are magic in the mids, they have no balls nor any super HF. Contrary to you, while I appreciate pure mids, not to the extent that ill accept to have the purest mids without enough bass.

Now we are getting somewhere. 
Someone why has owned and is willing to offer his critique of the strengths and weaknesses of *wide band/FR/High sens silnger drivers*

~~~Excel in the mids~~~
As I've mentioned , my cd/LP collection is all classical. Thus my criterion that a  speaker voices midrange, from say,, 1khz-10khz with the highest possible fidelity. Picking up the subtle nuances spread throughout a  classical recording. 
Actually I can **almost** live with this cheap 4 inch chinese *wide band*, caveat here is ,  needs bass and a  high end 12k+ hz tweeter. 
The bass in the Seas W18's although sens is  low at 87, will work for my needs, =  cello section, kettle drums.
Highs,, well I can find some horn to take care of the 12k+ hz's.  
Its always beeen a  issue to find the midrange section that my classical music requires to note all the tinest nuances within a  full range orchestra. 
Upon experimenting with various cheap chinese single drivers,,seems this design holds the promise to present my classical music like it should be presented. 

This is the purpose of this topic. 
Midrange.
If we placea  curtain over vaious speakers, the higher sens, will come out ahead as most notable in the midrange.
As noted by lonemountain above, where he states **the higher esns will be noted  as a superior image vs the xover/low sens** I am paraphrasing his ideas. 

Again, if the bass is weak in the wide band which  is under consideration , I am prepared to keep the Seas W18E001's as bass.
If the 12K+ hz, I find are rolled off, , again, the Magnovox horn will work out. 

~IF~ the wide band that I am looking at, voices midrange 1K-10K with the fidelity I hope for/expect/demand,,,then  the reseach/testing will have paid off. 
Others may choose to follow my path, or at least consider some of my ideas  and go on their own project to a  **Frankenstein*.
