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.
A design by John Hilliard, Altec Lansing Voice of the Theatre systems originally targeted movie theaters. The entire series was gradually expanded for use in general sound reinforcement and later converted in extreme high-end audio segments for hi-fi home use. Dorsey knows cinema sound inside...

After reading the above article, I had decided to go for active bi amplification without using internal network.
I use Lyngdorf 2170 which has speaker output, analog output and digital output with highpass or lowpass options.
I set the highpass at 500hz on digital output and going through my dac and integrated amp to drive treble horn.
Initially, I had tried to use speaker output of Lyngdorf 2170 with lowpass at 500hz to drive bass unit of Altec A7.
But bass sound is lagging behind the sound from treble horn.
Thus I had used analog output with lowpass at 500hz to Crown XLS 2502 which drive
bass unit of Altec A7.
But bass sound is still lagging behind the sound from treble horn.
Then I had used analog output with lowpass at 500hz to Rogue Cronus Magnum II which drive
bass unit of Altec A7.
Now it is working fine with treble horn.
Many people may think that SS amp sounds faster than tube amp but it is on the contrary.
I had used Telefuken ECC 83 and Amperex ECC 82 in Rogue, but after replacing Amperex with GE 12bh7a tubes, Rogue sound more robust on bass.
After getting rid of internal network, Altec A7 sounds more transparent with clean details.
Since I am happy with sound out of Altec A7 after active bi amping, I retired Lansche 4.1 to attic on the third floor.
Please note that I had been using Lansche 4.1 since 2006 after buying it new at 50k$.
P. S. ticking noise is from my chair while I reord the music sitting in the sofa.
