Vintage vs Modern speakers.

Some folks make the  claim , can't judgea  speaker via YT compression/+ computer cheapo speakers,,guess headphones  would be better,,,but anyway.
Honestly, both have MASSIVE SPL /Soundstage.
My rm is small and I listen at very near field at low/mid SPL, So neither would work for me. But to chime in a  answer, honestly I hear some over hang in the upper bass/low midrange, that notorious section where most speakers get all hung up.
I mean if you like huge GIGANTIC SPL,, soundstage, then yeah either one will work. 
Here give mine a  listen. 
Clean/clear, zero over hang /bloating in neither  upper bass nor low mid section
The upload cam is a cheap Sony, all I could afford.
So suffers from the cheap upload, But you get a  vague idea anyhoot

Be honest, if you don't like it, just say so.
ain't gonna hurt my feelings.

I am happy to have both.

~~~~~~~~~~~~~~~~~~
I morphed both low sens and high sens together, Best of both worlds , separate cabinets  but one   cohesive meshed soundstage.
Best of both designs. 
Could I be happy with only 1 single WBer,
Sure i could,
 Could  I be happy with a  single low sens speaker?
No never again.
 I could not, will not.
But both together, provided the low sens midwoofer is very well behaved. 
This is the caveat, the lone condition. 

I have yet to read the above article, maybe  when i have time will do so.

What I hear in both speakers is called
Resonances
Most folks , as yourself, have absoluetly no issues with resonances.
All speakers have soem degree of resonances. 
Some more, others less. I tend towards the very lowest possible resonances throughout the entire midrange say 200hz-5khz-6khz.
This is where my ears perk up intensive and alert to this mid zone. 
Place you speakers in a  smaller room and then you will be able to more detect  these  resonances = aka The Nasties.

As i say, most audiophiles fall in love with a certain speaker and have no issues with the resonances, they somehwo block these nasties out or just accept the good with the bad. Or they have not heard a spaeker with very low resonances thus have no reference point to compare.
I have past reference speakers thus I know what  designates acceptable level of resonances and what should be a  reject. 
Few speakers qualify for my acceptable level of resonances.

My speaker system still in development has shown extremely low level of resonances and I have futher developments to work out over the comming 6 months. 
It will  be the finest speaker on the planet, within the parimeters of this size and design and in most categories of critque.
If we give points to each quality ina  speakers voice, I think my design will come out top dawg.
Your 2 speakers have more SPL,  and so, you get high points there.
Mine will offer slightly less SPL but will have superior midrange etc etc.
All due to  thanks to recent developements  in WBer  designs. 
No I could not come around to either of your speakers.
