How to replace an 8 Ω, 0.5 W speaker with a 8 Ω, 1 W speaker? [closed]

Question

I have a cuckoo clock melody circuit that is connected to the 8 Ω 0.5 W speaker and I want to replace it with the 8 Ω 1 W speaker. When I connected it the output was not that much great as the 0.5 W speaker. What will change do I need to do?

Actually, I want a more brisk and strong sound from my cuckoo melody clock so replacing it with a bigger size and configuration speakers but it looks like the circuit output drive value is lacking to satisfy the required drive value for an 8 Ω 1 W speaker, i.e. (Drive Value) 5.657 V_PP to 8 V_PP.

Kindly suggest a modification for achieving the same.

Here the ORANGE wire is negative and red one is positive output to the speaker

Answer 1

That watt rating is not what the speaker requires or a measure of how loud it is;
it simply tells how much power the speaker can handle without burning up.

So of course two 8 Ω speakers will sound identical in volume if they are equally sensitive, i.e. can produce equal decibels at same power fed into them.

It won't change how much power the circuit can output to speakers.

What you can do is to put a 6 Ω or 4 Ω speaker to get more watts into the speaker, but it is unknown if the source can drive a heavier load.

Another option is to get an 8 Ω speaker with higher sensitivity, to get more decibels at same wattage.

A final solution could be to reverse engineer the circuit to figure out how to get more amplitude out of it, or how to add a separate amplifier if even possible.
