I want to generate a low freq movement for this loud speaker coil by using a function generator sine output. With the function generator I can generate a sine wave between 0.2Hz up to 100Hz with amplitude up to 2Vpp which is enough for my purpose. I want the coil move between 0.2Hz up to 100Hz.
But the thing is the loud speaker coils passes high currents. So this could be done by a big expensive audio amplifier with many stages. In my case I'm not interested in audio quality noise ect. but just the crude movement of the coil.
60 W 8 Ohm are the specs for the speaker.
I think that means at 60W the coil will pass from the formula P = I^2 x R --> I = 2.7 Ampere rms current which for a sinusoidal wave a sine with +/-3.8 Ampere amplitude.
Can a single push pull stage like shown here with two power MOSFET work for the purpose? If I'm in correct path, what MOSFET parameters should I look into?
