maximum power transfer

[bhuvaneshnick]

if u have 8 ohm load resistance(speaker) in series (voltage divider circuit) with another resistor(?)

what resistance do u choose same 8 ohm as load or less or high
i have heard by many to choose same but i dont know reason.plz explain me detially.thank you in advance

A speaker resonates which makes it sound bad. Therefore modern amplifiers DO NOT produce maximum power transfer, instead they are a voltage source with an extremely low impedance of 0.04 ohms or less to damp the resonances of a speaker. Look at Damping Factor in Google.
