Loads of good advice above get a meter on it first and check the coil is still 4 ohms, no lose cables as stated between socket and speaker coil. it won't be exact 4 ohm as you can only measure ohms not impedance, if that is OK then as above it is probably the moving diaphragm coil that is damaged these can be bought separately. A BW is better than a [b]cheap[/b] Eminence Just looked at the Link, see how small the vented pole piece is and the efficiency, you will need to drive this harder for the same volume, it is 3dB down on the current BW need to double your watts to get back that 3 dB
