Does anybody know what is the impedance of a HSN9326A mobile speaker ?

Thanks

Unless its an amplified speaker (I'm not familiar with the model number), there are a few ways you may be able to tell.

Method #1: Open the housing up and look at the back of the speaker. The impedance of most small speakers like are used in these things is usually printed on the magnet.

Method #2: Read the speaker with an Ohm meter. This is not an exact science, as Ohms and impedance are a little different, but it will usually get you somewhere in the ballpark. IIRC, a 4 Ohm speaker will usually read somewhere around 3 Ohms, an 8 Ohm around 6 Ohms, a 16 Ohm around 13-14 Ohms.
