Actually, the OP wants 56V p-p to each 4 ohm speaker which is 100W that is too much for one LM3886 amp. The applications note shows two amps in parallel (with low value series resistors at their outputs) then the power into 4 ohms is about 110W.
As I told I have taken apart each speaker from an amplifier module containing one LM3886. I want they work in my liner speaker design just like they have done before (i.e while they were connected to said module), Again, I will not get such situation if I put whole speakers in series/parallel.
By put all speakers in parallel the net impedance across the net connection would be 0.4 ohms, It means that using a bridged amplifier out of 2 LM3886's would not be helpful (by using a bridged amplifier out of two LM3886's I can drive a 8 ohms load which is completely useless).
There are 2 methods in my mind (I do not know any reasonable third method yet having the maximum output power for each speaker if needed).
1.feeding each speaker through separate amplifiers.
2.feeding whole speakers connected in parallel (thous having a 0.4 ohms load) through a Parallel amplifier (i.e using several LM3886's and put the output of them all in parallel).
Which method do you think is better please?
P.S Can I use 2 or more power transistors as drivers somehow to honestly be able to connect the 0.4 ohms loads to them without any problem yet getting the maximum of power??
