Vintage vs Modern speakers.


Most people have wrong belief that modern speaker has more clarity and details than vintage speakers
Recently I got 50 years old Altec A7 which sounds much better than my expectation.

I had kept Lansche 4.1 with plasma tweeter for 16 years which is still regarded as modern speaker.

You judge ths sound of Lansche 4.1 which go down to 20 hz and Altec A7 whcih go down to only 31.5 hz but more robust bass from the following Youtube videos.
Surpising thing is that Altec A7 give as much as details as Lansche 4.1 with plasma tweeter.

Which do you like better between Vintage(1) and Modern (2) judging from the Youtube videos?

Lansche 4.1 is also high efficiency speaker (99db/w spec but real no is around 94db) which can be drive by low power tube SET amp

Thus I am driving two speakers with tube amplifiers.

But they sound slightly different.

Altec with 99db/w efficiency give no strain even if I raise the volume to ear aching level.
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.

The Altec has more immediacy, more presence, more you are there (or is it, they are here?) feel to it.  But then when heard against the Lansche, the Lansche make the Altecs sound a little lean (i.e. not full-bodied) in the timbre department.  The Lansches sound to me as if they would be more forgiving on poorly recorded music.  Fascinating comparison.  Congrats.

Thanks a lot for your kind comment.

You are spot on!

Now I t drive Altec A7 with Rogue Cronu Magnum II fitted with Telfuken and Amperex Nos tubes.

It give more full bodied and relaxed sound.
