Re: op-amp problem

Probably you would need a power amplifier and not a normal Opamp

The small load resistance of the speakers would need a high current handling capability which cannot be provided by normal Opamps...

Re: op-amp problem

Do u want for your speakers,then try op-amp with class AB output stage,they are good for audio applications.

Ru planning to design the opamp or else off the shelf.
