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.

Thanks for useful experience of you.

My listeing room (actually living room on the second floor) is large

17ft wide 30ft deep 20 ft high and open to the third floor attic.

That may be the reason why I get good sound from Altec A7.

Lansche also sound well in small space too.

Billie Holiday’s voice sounds warm and sentimental through Altec A7.
     That’s Ella Fitzgerald not Billie Holiday!

Altec A7s need to be in 8-10,000 ft3 room minimum, otherwise the 2K bump will drive you crazy, likewise they really are at their best with a tube amp. Those big 515 woofers kick back a lot of EMF that most solid state amps weren't designed to handle. That back EMF can trigger current limiting, or leak into the feedback loop, neither of which helps sound quality.

But, in their place, and with a proper amp, their dynamics and clarity will amaze you.

Thanks a lot for your valuable opinion.

My room is kind of marginal although it could be regarded as big.

I use only tube amplifiers except driving subwoofers.

Accuphase DG-68 Digital Voicing Equalizer

We hold these truths to be self-evident, that all men are created equal. A great conceptsound enough to serve as the foundation for an independent democratic nation.

www.stereophile.com


It seems that JVS had been fascinated with Accuphase DG-68 Digital Voicing Equalizer .



https://www.accuphase.com/historys/images/dg-28.jpg


I had been usin DG-28 model since 2001.



I set up DG-28 last night after 11PM.


Using the mike, it scans 64 frequencies and then adjust the spectrum in the digital domain.


It has 4 pre sets so that I can choose the adjusted results for 4 different speakers.


Lansche 4.1 tends to sound sweet and warm but after room equlaization, it’s sounds get sharper and crispy.


The result with Altec A7 is very satisfactory.


A7 tend to be a little bit too aggressive in the treble.


I mean it give slight harsh edge from time to time.


But room correction and equalization through DG-28 seems to ameliorate such harsh edge.

After equalization, Heifetz’ s violin sounds warm and full freshed.

But without equalization, his viloin sounds somewhat metallic.

After equalization, the bass seems to be little bit tighter and more extended but not a day and night difference.



To conclude, I am happy with equalization on Altec A7.


The most pronounced effect is to get the treble clean and make violin sounds warm and full freshed.
