Connecting a hundred 8 ohm speakers or a Pleiades speaker to a 300B single ended class A power amplifier

At your own risk.


Working with high tension (voltage) can be very dangerous.


Take all safety precautions.


Single ended class A amplifiers have the least distortion near to the x axis where most of the music is.


And they give a natural, similar to many processes in nature, "distortion" at the peaks of the signal. This sounds very nice. And this process of treating peaks has similarity to practice of great mastering studios, FM radio station processing etc. Of course the great mastering studios use tube equipment and huge multi driver speakers. If memory is correct an example is the mastering studio of Bob Ludwig.


So why not making the speaker load equal to the tube's internal resistance rather than the x3 rule. Theoretically we will have more of this distortion when the levels are high. And according to the maximum power theorem the power output will be the greatest.


So how about 100 8Ω small full range speakers each with a low reasonant frequency all connected in series for each channel. Each will move a little, so distortion will be low. All of them will make a huge effective vibrating area giving amazing bass.


The 800Ω total impedance will be directly connected between anode and power supply (+), be extremely careful, take all precautions.


Each small speaker is light so the high frequency response will be great too.
