That might just be a metaphor for life. Mine has always been: "The positive real roots disappear, or the system does." I actually like yours better; it is closer to common reality.Speakers are usually 8 ohms and amplifiers are usually designed to drive one 8 ohm speaker with its rated output power.
1) One 25W speaker on a 100W amplifier= The speaker blows up.
2) Two 25W speakers in series on a 100W amplifier= Both speakers blow up.
3) Four 25W speakers in series on a 100W amplifier= The speakers survive but sound "boomy and muddy" since resonance damping from the amplifier is poor.
If two or more speakers are connected in parallel then the amplifier might blow up.
Do the simple math:What happens if you keep paralleling the speakers? Let’s say you got it down to 0.1 ohm. It’s just a thought exercise.
The amplifier in the system that I was referencing is used primarily for speech, and occasionally for singing, never at a loud level. That amplifier is part of an 8 channel mixer board and is used only because it is on hand and paid for and so could provide the number of inputs needed. I mentioned the power versus load impedance only to show that in many amplifiers power delivery depends a lot on load impedance, and so there was a way to connect the speakers that would be safe. And remember that not everybody can hear that 0.01% distortion in a 35dB violin solo.A solid state amplifier does not use an output transformer so the power output depends on the load impedance.
A "400W" amplifier might produce 400 peak Watts at a horrible 10% clipping distortion. Then its real output power is 200W at 10% clipping distortion or 160 real watts at low distortion.
If a solid state amplifier produces 400W into 2 ohms then its output into 4 ohms is probably about 225W and its output into 8 ohms is probably about 127W.
Four 8 ohms speakers in series are 32 ohms and the output power in each one will be only about 10W.
Since we don't know if the amplifier's rated 400W is peak or very distorted then the power in each speaker might be only 5.6W.
The speakers will have no resonance damping produced from the extremely low output impedance of the amplifier so they will sound like bongo drums, not electric guitars.
No audio power amplifier is 100% efficient. If it is electrically or thermally overloaded then it blows up or it protects itself by shutting down. Most IC audio power amplifiers protect themselves from abuse.Well it depends on how efficient the amplifier is :j. If the amplifier is 100% efficient there should be no problem as long as your power supply can support it. Like I said it’s just a thought exercise.
unfortunately there's no hint of impedance - there are , what i don't have - the 2Ω speakers then 4Ω , 8Ω , 16Ω , 32ΩI use 4 25 watt speakers
